Samsung Foundryで、5nmプロセスの情報を確認した。

5nmプロセスの歩留まり率:

「Samsung Foundryで生産されている5nmプロセスの歩留まり率」が、「量産を開始する目標値に未だに達していないこと」を、確認したと報じた。

INFOSTOCK DAILYによると:

  1. 5nm EUVプロセスの歩留まりは、50%に達していない。
  2. 生産歩留まりをあげるため、全力で取り組んではいる。
  3. しかし、大きな進展がない状況と述べたという。

また、次のようにも伝えている。

  1. Samsung研究部門が別の生産方式を開発した。
  2. 歩留まり向上のめどは、立ってはいる。
  3. しかし、プランB採用の決定が遅れている。

同紙によると、

「一般的にDRAMでは、90%以上が目標歩留まり」である。

「システムLSIでは、70%台が目標歩留まり」としているという。

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.”
