三星：5nm EUV工艺的挑战：良率低
-韩国媒体报道-
韩国媒体：INFOSTOCK日报
在三星晶圆厂确认的有关5nm工艺的信息。
5nm工艺的成品率：
“三星铸造公司（Samsung Foundry）生产的5纳米工艺的成品率”已证实“尚未达到开始大规模生产的目标值”。
根据INFOSTOCK日报：
5nm EUV工艺的成品率尚未达到50％。
我们正在竭尽全力提高产量。
但是，他说并没有重大进展。
它还报告如下。
三星研究部门开发了另一种生产方法。
产量提高的前景一直保持不变。
但是，采用计划B的决定已被推迟。
根据报纸
“一般来说，使用DRAM时，目标产量是90％或更高。”
他说：“对于系统LSI，目标良率在70％范围内。”

Samsung Electronics has not obtained the yield in foundry pre-processing
The possibility of the first quarter loss –
[Infostock Daily=Senior Reporter Kim Jong-hyo]
While major decisions have been delayed due to the absence of Vice Chairman Lee Jae-yong, the semiconductor foundry division of Samsung Electronics is facing challenges.
The company has not been successful in achieving the yield of the system LSI semiconductor pre-processing in production.
According to the sources and information collected by Infostock Daily,
Samsung Electronic foundry
is not exceeding the target yield of the next-generation 5-nano semiconductor in production.
An official familiar with the internal affairs of Samsung Electronics said,
“The yield of 5-nano system semiconductor pre-process does not exceed 50%. Our team is making all-out efforts to obtain the yield, but we are not making much progress.”
The official said,
“the Samsung Semiconductor Research Institute has achieved the target yield by applying a groundbreaking production method. As an alternative, proposals to adopt a new production method are made, but the executive decision is being delayed.”
In general, DRAM target yield is more than 90%, but the target yield of system LSI is in seventies.
Even if the foundry business has the orders at record level, the profit is declining as production increases due to increase of production costs driven by the low yield rates.
The low yield
is also affecting the overall profits of the division, and It raises the possibility of a loss in the first quarter.
Samsung Electronics stated, “There is no problem with the yield of the 5-nano system LSI pre-process.”
