Semiconductor scarcity: How the automotive {industry} can succeed



In the course of the earliest days of the COVID-19 disaster, automotive headlines targeted on the large drop in automobile demand. However for greater than a yr now, issues have shifted to the availability facet. Though automobile orders have surged to surprising heights, a scarcity of automotive semiconductors is forcing OEMs to shut manufacturing traces or take away some well-liked options, akin to heated seats, from their choices.

We first explored the automotive chip scarcity in a Could 2021 article, noting {that a} fast repair was seemingly inconceivable. The state of affairs has worsened since then, and the latest drop in automotive revenues is essentially occurring as a result of OEMs and Tier 1 suppliers can’t procure ample portions of chips and should delay automobile manufacturing. Whereas producers of laptops, white items, and different gadgets have additionally minimize manufacturing due to semiconductor shortages, the repercussions within the automotive {industry} have been extra extreme. Some premium OEMs have been in a position to safeguard earnings with selective manufacturing and gross sales methods designed to optimize margins. This technique, nonetheless, could lead to a scarcity of lower-margin automobiles and will trigger excessive fluctuations in demand for automotive chips.

Russia’s invasion of Ukraine has launched additional uncertainties to each the semiconductor provide chain and automotive demand. As an illustration, Ukraine provides 25 to 35 p.c of the world’s purified neon gasoline, and Russia provides 25 to 30 p.c of palladium, a uncommon metallic used for semiconductors.


One other wrinkle: many semiconductors are transported by air, however transport prices have considerably elevated whereas obtainable delivery quantity has dropped. And one more drawback: OEMs have been unable to acquire important automobile elements, akin to wiring harnesses, and have lowered their manufacturing volumes in response, which has added much more uncertainty by lowering demand for some semiconductor-based elements.

Given the continuing instabilities within the semiconductor provide chain, the automotive {industry} ought to take into account refining its technique. Firms can begin by specializing in the implications of three important actions that type the muse for strategic scarcity administration: the creation of sturdy expertise maps, dependable short-term demand planning, and steerage for long-term demand planning.

Components behind the escalating challenges in semiconductor provide

Greater than two years into the pandemic, the hole between chip provide and demand has widened throughout all semiconductor-enabled merchandise. Whereas gross sales of all shopper items plummeted within the first half of 2020, and automotive gross sales dropped precipitously—as much as 80 p.c in some areas—demand rebounded greater than anticipated later within the yr, continued to develop in 2021, and stays sturdy in the present day. The high-tech sector, particularly, has seen gross sales volumes improve, partly due to adjustments wrought by the COVID-19 pandemic. The expansion in working from residence, as an illustration, has contributed to a better demand for wi-fi connectivity and PCs. These market shifts have rippled again to have an effect on demand for semiconductors and different elements. Throughout virtually all industries, the demand for semiconductors in 2020 and 2021 exceeded prepandemic forecasts (Exhibit 1). And this implies automotive OEMs and Tier 1 suppliers are more and more competing with corporations in different industries for chips.


Overall demand for semiconductors continues to increase.

Though the chip scarcity is affecting many industries, the automotive sector has some distinctive traits that exacerbate the issue. As an illustration, many OEMs and Tier 1 suppliers observe a “simply in time” manufacturing technique through which they order semiconductors and different automobile elements near manufacturing to optimize stock prices. When automobile gross sales fell in early 2020, OEMs and Tier 1 suppliers decreased their chip orders, leaving them low on stock when demand started to get better. Firms in industries that don’t observe a just-in-time ordering method have been in a greater place, particularly since some had secured additional capability when automotive gamers canceled or lowered their orders.

On the demand facet, automotive corporations have way more complicated and customized merchandise than corporations in lots of different industries. In consequence, they could have extra issue predicting their semiconductor wants, and demand could fluctuate. On prime of this, the automotive {industry} should observe stringent security necessities that necessitate using particularly validated semiconductors and outlined manufacturing amenities alongside the entire worth chain.

Amid all of the uncertainty, demand for automotive chips is rising steadily as automobile electrification, superior driver-assistance techniques (ADAS), and connected-car options turn into extra well-liked.

The rising chip scarcity is prompting the automotive {industry} to order surplus semiconductors—about 10 to twenty p.c greater than wanted—to make sure stock and safeguard manufacturing. This “bullwhip impact” has been documented throughout numerous industries for a few years. In 2022, as an illustration, OEMs and Tier 1 suppliers are anticipated to put orders for sufficient automotive chips to outfit about 120 million new automobiles, however annual automobile gross sales are forecast to be about 83 million.


Firms throughout industries are additionally inserting extra advert hoc orders, usually at an unusually excessive common gross sales worth. The brand new ordering developments don’t present fast reduction, given the lengthy manufacturing occasions for chips, and so they introduce further uncertainty into the semiconductor provide chain.

The necessity for options

As we famous in our earlier article, no short-term options exist for the automotive semiconductor disaster. The lead occasions for chip manufacture common a minimal of 4 months if capability is out there and no growth is required; in any other case, it is going to seemingly take a minimal of 18 months (Exhibit 2). Rising manufacturing would possibly appear to be the plain reply, but it surely takes greater than three years to construct a brand new fab and ramp up wafer manufacturing. Lead occasions for manufacturing gear have additionally elevated over the previous two years as a result of COVID-19 sophisticated provide chains, making growth much more tough.


Lead times for semiconductor production can exceed four months.

The semiconductor provide chain was already underneath stress earlier than the pandemic. COVID-19, mixed with latest challenges associated to energy outages, pure disasters, and geopolitical uncertainties, has solely intensified the issue. After carefully analyzing the {industry}, together with these latest provide and demand developments, we’ve got concluded that the semiconductor scarcity will seemingly persist in chosen expertise nodes for a minimum of the subsequent three to 5 years. The continued scarcity is partly a results of long-standing structural elements, akin to inadequate capability, however the latest conduct of automotive corporations—overordering and growing inventory ranges—can also be contributing to the issue (Exhibit 3).


A combination of structural issues and crisis reactions has led to semiconductor shortages.

For nodes better than 90 nanometers (nm), that are in excessive demand within the automotive {industry}, the scarcity is prone to persist for 2 causes. First, the semiconductor {industry} is unlikely to deal with the structural causes for this scarcity, as a result of mature nodes have low revenue margins. Second, some finish clients recognize the enticing worth level of mature nodes and have a restricted incentive emigrate to decrease node sizes, due to the extra growth and qualification prices, in addition to the restricted availability of R&D workers.

For wafers from 22 to 65 nm, the scarcity is not going to absolutely resolve over the short- to midterm, however it might reduce if semiconductor corporations improve their provide, as anticipated. Total, nonetheless, it’s tough to foretell the dimensions of the demand–provide hole for particular merchandise on this group, given the excessive heterogeneity of machine varieties and applied sciences.

An up to date method: Sustainable management rooms and an intensified long-term technique

As corporations ponder the semiconductor scarcity, they’re contemplating each their short- to medium-term wants, in addition to their long-term resiliency and survival. Our earlier article described some methods which can be applicable for each intervals, and we’ve got refined them to replicate latest expertise.

Many OEMs and automotive Tier 1 suppliers have already established management rooms that mix workers from procurement, provide chain administration, and gross sales to assist be sure that they’ve a ample provide of semiconductors. Whereas these groups have developed some efficient options to handle the fast provide–demand scarcity, they usually lack the required instruments, expertise, or capability to handle it over the midterm and develop strategic options. To treatment the commonest issues, corporations can undertake a number of actions (Exhibit 4).


Several factors may complicate the creation of a technology road map and planning, but solutions exist.

Stronger expertise street maps

In lots of instances, corporations create unclear expertise street maps that don’t actually outline their semiconductor wants. As an illustration, the street maps could comprise restricted insights concerning the semiconductor content material in next-generation merchandise or fail to account for all elements affecting semiconductor provide and demand, such because the influence of custom-vehicle orders.

Creating stronger expertise street maps will permit Tier 1 suppliers (or doubtlessly OEMs within the case of sure elements, akin to central computer systems) to extend transparency, permitting the businesses to steer their product growth extra strategically. They might determine to reengineer chips, maintain discussions collectively with the OEMs to determine alternatives for drop-in elements, or collaborate with OEMs to scale back variations within the large-volume discrete and analog gadgets throughout completely different automobile elements (thereby lowering variations in demand ensuing from custom-vehicle orders).

Improved short-term demand planning

Along with strategically designing merchandise, OEMs and Tier 1 suppliers can present better transparency about short-term automotive chip demand to semiconductor suppliers. In different industries, akin to digital gear, producers and suppliers share details about demand and provide throughout the complete provide chain, which helps floor potential issues earlier than they escalate. If one provider seems to be having issue getting the elements obligatory for its merchandise, the producers know that this delay will ripple again to have an effect on them. Traditionally, the automotive {industry} has not required this end-to-end transparency, due to its market energy and regular progress, and OEMs and Tier 1 suppliers haven’t but achieved this. To achieve the specified degree of perception, OEMs and suppliers can use a generally agreed upon nomenclature, akin to a shared definition of chip households and expertise nodes, in demand forecasts.

If one provider seems to be having issue getting the elements obligatory for its merchandise, the producers know that this delay will ripple again to have an effect on them.


OEMs and Tier 1 suppliers that put money into data-driven processes and automatic instruments will enhance the standard of their end-to-end planning course of. Some have already taken steps on this path by offering ready-to-use dashboards for monitoring merchandise alongside the availability chain, however many extra alternatives stay throughout features. Gross sales, for instance, might use superior analytics to forecast required demand. And manufacturing might use digital instruments that assist allocate semiconductors to the appropriate areas, fairly than making advert hoc selections, to maintain automobile manufacturing on monitor. Groups may use danger cockpits to scale back the possibility of surprising semiconductor shortages. These steps may help deal with many points that now intrude with chip provide, akin to an absence of perception concerning the semiconductor content material of next-generation merchandise.

Higher end-to-end planning alongside the availability chain, mixed with better use of data-driven processes, will make OEMs and Tier 1 suppliers throughout the automotive {industry} extra dependable and doubtlessly most well-liked companions. These actions may also allow strategic contractual levers, akin to long-term take-or-pay commitments by Tier 1 suppliers, that can improve the probabilities for strategic partnerships between semiconductor suppliers and automotive gamers.

Higher short-term planning may also assist OEMs and Tier 1 suppliers type extra strategic relationships. As they work collectively, OEMs ought to do not forget that demand estimates could also be inaccurate and take steps to mitigate dangers or share the burden with their Tier 1 suppliers. As an illustration, a contract would possibly state that an OEM will decide to utilizing a selected chip expertise 18 months prematurely. It might provide the OEM some restricted flexibility to change the order and the choice of switching to a unique expertise till six months previous to cargo. To make such preparations work, OEMs should specify the precise elements wanted (fairly than the automobiles being manufactured), since this immediately interprets into demand for semiconductors.

Improved transparency alongside the entire provide chain, together with provide–demand matching, is a prerequisite for having OEMs and Tier 1 suppliers implement midterm inventory-management methods that can cut back danger. This stock administration can permit Tier 1 and semiconductor suppliers to substantiate that they will fill orders as a result of the availability–demand evaluation provides them extra transparency and permits them to allocate chips to potential clients earlier.

Improved long-term demand planning

Moreover short-term demand planning, OEMs and suppliers might construct a long-term perspective on demand. It will permit them to contemplate collectively investing in initiatives involving mature nodes. Alternatively, each teams could codevelop semiconductors in superior or modern nodes. These methods will permit them to share the monetary burden whereas enhancing the availability of low-margin or extremely modern applied sciences.

Even after OEMs and Tier 1 suppliers enhance their technique, management rooms could turn into semipermanent options within the automotive {industry} till the semiconductor disaster is resolved; corporations ought to subsequently develop some long-term expertise methods for staffing them. Many staff have been juggling a number of priorities and coping with surprising challenges because the pandemic started, and asking them to serve on a management room crew might sound overwhelming in these circumstances. To cut back the burden, automotive corporations can create environment friendly management room processes and instruments that streamline duties. They will additionally guarantee a secure influx of expertise by asking completely different staff—both present workers or new hires—to take part on the crew, permitting different staff to rotate out.


OEMs and Tier 1 suppliers have shortly moved into firefighting mode to take care of the short-term chip scarcity, however much more decisive motion is important, particularly because the state of affairs is prone to persist far into 2023. Taking a tough have a look at inside processes, contract conventions, and product options will go a great distance, as will better transparency and cooperation with semiconductor suppliers. These OEMs and Tier 1 suppliers which can be keen to experiment and examine inventive options could acquire the best benefits.
