TSMC's wafer price hike reflects the tightness of supply


Tuesday, September 21, 2021

The prolonged IC shortage, which is expected to last till 2022, is the major driving force for wafer price hikes in the foundry industry, from most second-tier vendors during the past 1-2 years to Taiwan Semiconductor Manufacturing Co. Ltd (TSMC) recently. With the latest notices to its customers, TSMC will raise its wafer prices across the main nodes mainly from the beginning of 2022. The company has maintained its wafer prices for quite a long time when compared with its smaller competitors. The change in its pricing strategy from 2022 implies not only stronger market demand going forward, but also that the capacity tightness will persist in the next few quarters.

Aside from the market mechanism, the new price strategy also protects foundries from both short-term and long-term uncertainties, such as double-booking effect (massive order cancellation), supply chain disruptions (increase in shipping cost) and geopolitical complexities, which may affect their production margins/profits.

We have seen wafer price hikes from second-tier vendors since 2020, especially in the matured nodes if we define them as the technology geometries at 22/28nm and (numerical) above. The price increases were 25-40% over the base of Q1 2020 and are likely to see another 10-20% hike in 2022. Relatively, wafer price hikes in advanced/leading-edge nodes below 10nm are milder, while we could see an average of 5% increase for 7/6nm nodes as per TSMC’s latest quotes for 2022. In Exhibit 1, we show the prices for various nodes for leading foundries during 2020-2022.

As we can see, matured nodes have seen wafer price hikes for almost a year, with the price gap in some nodes (like 28nm vs 40nm) narrowing driven by a higher percentage of price hike from smaller foundry players like UMC and SMIC, which enjoyed strong profit boosts during H1 2021.

How to forecast wafer prices beyond 2022? It is largely subject to the demand and supply outlook on major IC products in each node. We have conducted an analysis of all matured nodes in our report published on August 26. In our view, while the ongoing global IC shortage will begin easing from late 2021, especially in DRAM/NAND, logic ICs fabricated in mainstream/matured nodes in the foundry will remain in a tight position and will not reach the demand-supply balance until mid-2023. For foundry customers (fabless and IDMs), the impact of supply shortage weighs much greater on their business compared to the 10-20% increase in wafer cost, which they might pass to their end customers (device ODMs/OEMs).

Impact on smartphone demand after wafer price hike

Logic ICs (the chips largely fabricated in foundries for smart devices) account for 30-40% of the total BoM (Bill of Material) cost depending on the selling price. Assuming other component and assembly costs are stable moving into 2022, logic IC price increases will be added to the total product cost for smartphone ODMs/OEMs. Analyzing this impact, we conduct a sensitivity check for different price segments of smartphones under different percentages of price pass-through from logic IC vendors. For example, in high-end/premium models, if all vendors (from AP processors to power management chips) pass wafer price increases to OEMs, the smartphone cost increase from logic ICs is about 12% in 2022, demonstrated in the upper-left cell in Exhibit 2.

We conclude that the percentage of total smartphone IC price increase has a greater impact on low-end smartphone models since the chips from matured nodes (such as PMIC in 8-inch fabs, display TDDI from 90-65nm, and AP/SoC from 28-12nm) account for a larger portion of BoM in this segment. In the optimistic case for smartphone OEMs, the IC vendor might absorb half of the incremental cost, but we do not expect this to happen in early 2022 if smartphone IC supply stays tight.

What are the implications for the smartphone industry in 2022? While it is still early to judge the overall impact on shipments due to higher component prices, the cost pressure on OEMs appears more unfavourable in the mid-end segment under severe competition. This year, for instance, mid-end 5G smartphone sales have failed to meet expectations in China, and the situation may possibly get worse next year. In case of another 10% price hike without any meaningful feature upgrade, smartphones in the mid-end segment may lose the battle to cheaper 4G and 5G models in many emerging markets. In developed countries and China, on the other hand, OEMs would prefer to promote more flagship/premium models, which generate higher sales dollars. We also expect 4G smartphone prices to increase, as OEMs are able to pass through the IC cost increase to end devices. As a consequence, the effect of wafer price increase might be negative on smartphone shipment growth but positive for the industry ASP (and net positive for the total market dollar size) next year.
