Contamination at TSMC fab reportedly ruins thousands of NVIDIA GPU wafers
An incident at TSMC’s Fab 14 B might lead to some GPU shortages additional down the road. According to Taiwanese information website ETtoday, a chemical contamination at the fab resulted in at least 10,000 faulty wafers, which might considerably impression many of its prospects.
The wafers have been reportedly contaminated by unqualified uncooked supplies, and TSMC has stopped utilizing this batch of materials and notified all affected prospects. In a press release to the Nikkei Asian Review, the corporate stated that it “found a cargo of chemical materials used within the manufacturing course of that deviated from the specification and can impression wafer yield”.
The drawback impacts TSMC’s wafers for 12nm and 16nm merchandise, which NVIDIA depends on for its Pascal and Turing GPUs. NVIDIA is just not alone although, and cellular chip producers like Huawei and Mediatek use these wafers as nicely. AMD’s upcoming 7nm merchandise just like the Radeon VII shouldn’t be affected, however the firm does use the affected processes in its Xbox One X and PS4 Pro chips.
Companies already face difficulties in getting sufficient wafers to make their semiconductors, so a set again on this space might lead to manufacturing delays and provide shortages. It’s not but clear if this can have an effect on provide to shoppers, however it would most likely depend upon the extent of the issue and the way rapidly it may be resolved.
However, TSMC appears assured that will probably be in a position to make up for the misplaced floor. It informed The Inquirer that it expects that almost all of the affected wafers could be made up in Q1 2019, with the rest being made up within the second quarter.
