As we all know, since entering 5nm, everyone has complained about Samsung's process is not good, with low yield, high power consumption and high heat generation. And also gave various examples to prove it.
, such as 5nm Snapdragon 888, is known as the Fire Dragon. Then the 4nm Qualcomm Snapdragon 8Gen1 is also a Fire Dragon. At the same time, because the yield rate was too low, it was rejected by and Qualcomm . Finally, Qualcomm transferred the order to TSMC to produce Snapdragon 8+.
The Snapdragon 8+ produced by TSMC is also a 4nm process, but it is obviously more powerful than Snapdragon 8Gen1, with lower power consumption and less heat.
According to media reports, the yield rate of Samsung’s 4nm process is only about 35%. Later, it was revealed that at 3nm, although Samsung adopted more advanced GAAFET transistor technology, the yield rate was even lower, only 10-20%, which was appallingly bad.
Therefore, customers are no longer willing to calculate orders based on the number of wafers, and are only willing to calculate based on the number of imported chips. Because the yield rate is low and the cost is too high, IC manufacturers cannot resist it.
So Samsung’s yield rate is so bad, what about TSMC’s? Recently, some media disclosed a page of TSMC's PPT content. It shows that the N3E process is progressing very well, with an average of more than 80%.
If true, it means that TSMC’s yield rate is 4 times that of Samsung. Under the same conditions, if Samsung produces one chip, TSMC can produce 4. This gap is too big. I wonder if Samsung will notice it. Envy, jealousy and hatred?
Samsung has always wanted to surpass TSMC in the foundry field. Especially when it came to 3nm, it took a breath and took the lead in mass production. It also adopted GAAFET transistor technology. It just wanted to be one step ahead of TSMC and then slowly expand its advantage. , eventually surpassing TSMC.
But judging from the current yield rate, Samsung still has a long way to go, and there are still many areas to work hard on. After all, the yield rate is so different, isn't it obvious who the customer will choose? According to TSMC's information,
uses a 3nm process. The power consumption of is reduced by 34% and the performance is increased by 18%. The density of transistor can also be increased by at least 18%. It will be fully mass-produced next year. When compared with Samsung, who is more powerful? .
