三星良率低到逼迫高通換供應商 - 工程師

Samsung set out on an ambitious plan to bolster its chip business by producing
semiconductors for other companies. However, one of its largest clients – Qu
alcomm – is now reportedly seeking the services of TSMC due to Samsung Foundr
y’s low yield.

A report by The Elec (via SamMobile) states that Qualcomm is even asking TSMC
to make a portion of its 4nm Snapdragon 8 Gen 1 chipset. This is despite Samsu
ng Foundry being listed as the sole manufacturer of the chip when it was first
announced. The decision barely comes as a surprise given that Samsung Foundry
’s yield for the Snapdragon 8 Gen 1 was only 35%.
高通決定把一部分包莖1訂單分出來，即使一開始號稱三星是獨家供應商。
考慮到晶片良率不到35%，這個決定也沒這麼意外

What this also means is that Qualcomm will partner with TSMC for its upcoming
3nm SoCs. The report adds that the Exynos 2200 has an even lower yield than th
e Qualcomm chip. So Samsung clearly has a lot of thinking to do.
其實三星自家的Exynos 2200良率更低

According to a source quoted by The Elec, Qualcomm executives and technical pe
rsonnel were physically present at Samsung Foundry’s units to oversee the pro
duction of the Snapdragon 8 Gen 1. This explains why Qualcomm’s chip witnesse
d a better yield than Samsung’s own Exynos 2200. But Qualcomm’s decision to
move to TSMC indicates that the yield troubles couldn’t be fully resolved.
為了搶救良率，高通其實有派長官和技術人員現場到三星的fab去盯場，這也解釋了為什
麼高通的晶片良率比三星自家的高。決定換供應商應該是發現良率問題無法解決

Last year, tech giant NVIDIA shifted orders of its new 7nm GPU to TSMC due to
Samsung’s yield issues. Moreover, the global chip shortage has brought enormo
us pressure on suppliers to meet demand. The low yield further adds to the com
pany’s woes. As for corporations like Qualcomm or NVIDIA, supply is everythin
g. So they’re left with no option but to make alternate arrangements.
