Tsmc lost $ 550 million because of contaminated wafers
Table of contents:
A few weeks ago we told you about a problem in one of TSMC's factories, in which tens of thousands of wafers had been contaminated by the use of low-quality materials. This forced the company to temporarily close the factory, generating delays of all kinds, and very important, since TSMC manufactures chips for companies like Nvidia, MediaTek, Huawei and even Apple.
TSMC announced millionaire losses due to thousands of defective wafers
TSMC has come out to communicate what the impact of these failures was, announcing that they have lost $ 550 million in wafers thanks to a bad batch of photoresist material that was delivered to them by one of the company's suppliers.
At this time the TSMC 12/16 nm wafers are believed to be affected by the defective materials, impacting the wafers on Fab 14B. It is unknown which products were affected by these defective materials, although TSMC's 12nm process is known to be used to create the latest series of Nvidia's Turing graphics cards.
To ensure high levels of product quality, TSMC has had to discard more wafers than expected, although the company claims that the wafers that were discarded in the first quarter will be offset in the second quarter. Fortunately, the manufacturer found that demand in the first quarter was higher than expected, adding an estimated $ 230 million in additional revenue in the first quarter. This partially compensates for the loss of $ 550 million.
TSMC has revised its revenue estimates for the first quarter of 2019, reducing its revenue projections from $ 7.4 billion to $ 7.1 billion. The company's gross margins will also decrease by a few percentage points.
TSMC is currently the world's largest chip maker, trusted by many major PC companies, including AMD and Nvidia.
