Because of the nature of its CoWoS chip packaging expertise, costs for synthetic intelligence (AI) chips manufactured by the Taiwan Semiconductor Manufacturing Firm (TSMC) are anticipated to extend within the coming months, based on a information report from Taiwan. Sturdy curiosity in AI chips from massive American expertise corporations equivalent to NVIDIA and Microsoft has supplied TSMC with a lot wanted orders through the ongoing downturn within the semiconductor business.

Nonetheless, one key constraint in TSMC’s chip fabrication course of is the packaging expertise that’s wanted for AI chips. TSMC has sometimes relied on CoWoS for its merchandise which are geared towards shopper use, and since an AI chip is incomplete with out packaging, the chip maker has to steadiness its chip fabrication and chip packaging capacities to make sure that it may ship merchandise to prospects in a well timed method.

Upstream Provide Chain Prices Due To Elevated Demand Can Make TSMC’s AI Chip Extra Costly

Whereas it is creating some information as of late, TSMC’s CoWoS (Chip on Wafer on Substrate) packaging expertise has been obtainable to prospects for fairly a while now. Work on 3D packaging, with applied sciences equivalent to Wafer on Wafer (WoW) and Built-in FanOut (InFO) has been happening with Apple for years, with a number of the packaging applied sciences being a part of the iPhone 7 in 2019.

CoWoS is a expertise that permits TSMC to stack a number of chip dies collectively and enhance their efficiency by putting them collectively on a silicon interposer. This interposer is, due to this fact, one of the crucial essential uncooked supplies for your entire course of, and it’s packaged on prime of a circuit board by way of bundle balls.

A report from Taiwan’s United Day by day Information (UDN) means that the rise in costs of those interposers will ultimately drive up the prices of AI chips made by TSMC because the chip maker’s provide chain expands its manufacturing capability.

Owing to the sturdy demand for AI merchandise, TSMC is investing billions of {dollars} into upgrading its packaging capability. The agency introduced a $2.89 billion funding into a brand new chip packaging facility in Taiwan in July, and recent business studies recommend that by 2024 finish, the agency is aiming to develop its packaging capability to 30,000 wafers per 30 days. TSMC has positioned orders for brand new packaging machines, and the worth enhance for the AI chips stems from the capability improve.

Based on business sources quoted by the UDN, TSMC procures the interposers for its CoWoS chips from United Microelectronics Company (UMC) – Taiwan’s second largest contract chip producer. UMC and ASE Group are anticipated to be the largest beneficiaries of the bump in demand for TSMC’s CoWoS merchandise, and so they have already obtained the primary batch of orders. The 2 corporations are at the moment producing and delivery these merchandise as TSMC rushes to fulfill the primary wave of information middle and different AI orders earlier than the present fiscal yr ends.

Trade studies additionally recommend that as a result of massive inflow of orders, UMC has already entered right into a scorching manufacturing run. By maintaining in thoughts the rising orders, the agency additionally plans to double its manufacturing capability for these merchandise. Interposers for the CoWoS expertise are produced in a UMC facility in Singapore, with the present capability sitting at 3,000 items. UMC plans to broaden this to no less than 6,000 items, and TSMC can be reported to outsource a few of its orders to ASE if its personal manufacturing traces turn out to be strained.
