Figure 1 shows that since 1998, only the automotive and communications end-use segments have gained marketshare.
Driven by the global explosion of smartphone demand, the communications market almost doubled its share of the IC market from 18.5% in 1998 to 35.0% in 2020.
Automotive’s marketshare increased from 4.7% in 1998 to 8.7% in 2019 before falling back to 7.5% during 2020.
The automotive share of the total IC market has never been greater than 9.0% while the communications share of the IC market peaked at 37.2% in 2013.
In 2020, the communications IC market was 4.7x the size of the automotive IC market.
In many cases, automotive ICs represent only a small portion of an IC supplier’s total sales. (At TSMC, the world’s largest foundry, automotive applications have never accounted for more than 5% of its sales.)
Producing automotive ICs does not typically require leading-edge technology—many non-memory automotive ICs continue to be manufactured on 200mm wafers—but it does require strict adherence to rigorous reliability and testing requirements and a commitment by the IC manufacturer to supply a customer’s long lifecycle needs.
It is also worth noting that automotive IC end-users are notorious for being tough negotiators, oftentimes leaving slim margins for the automotive IC supplier.
Despite the current automotive IC shortage, the ASP for many automotive IC products has remained fairly constant. For example, the ASP for automotive application-specific ICs was $0.96 in 2020 (15% less than the total ASIC market ASP last year) and only $0.95 in 1Q21.
Many IC industry headlines have recently focused on the shortage of automotive ICs, but given its relatively small size, strong growth in the automotive segment is not expected to significantly lift the growth rate of the total IC market this year. In fact, the 1Q21/1Q20 automotive IC market grew 23%, the same rate as the total worldwide IC market.
