The yield rate of the Snapdragon 8 Gen 1 chip produced by Samsung is only 35%
Yesterday, it was reported that the management of Samsung Electronics decided to investigate the low yield rate of advanced process chips (5nm/4nm/3nm). The content includes whether there is any wrong information in the process yield report submitted in the past and whether the funds used to improve the yield rate of advanced processes have been effectively used.
From the 5nm of the Snapdragon 888 to the 4nm of the Snapdragon 8 mobile platform, Qualcomm has suffered greatly. In the past period of time, it has often been reported that Qualcomm hopes to redistribute orders for high-end Snapdragon chips to TSMC, and the yield problem is one of the main reasons. According to The Elec, the current yield rate of the Snapdragon 8 Gen1 chip is only 35%, and the Exynos 2200 yield is even lower, which is very bad. It is said that the higher yield of the Snapdragon chip is due to the fact that Qualcomm has executives and technicians stationed in the Samsung wafer foundry, and the production is constantly revised. In contrast, TSMC’s N4 process yield exceeds 70%, which is enough to make Qualcomm excited even without considering performance and energy efficiency issues.
Due to Samsung’s long-standing yield problems in advanced technology, coupled with the resulting delayed delivery time, which led to a shortage of supply, forcing Qualcomm to prefer to pay extra to TSMC to add orders, rather than continue to wait for Samsung to ship. It was previously reported that Qualcomm hopes to launch a Plus version earlier this year to replace existing chips. It is to launch TSMC’s 4nm chips as soon as possible to get rid of supply and performance issues.
