Samsung Fou ndry is only one of the two contract chip manufacturers in the world that is cap able of producing semiconductors on the advanced 5-nanometer (nm) chip process. The efficiency of such processes is determined by what is referred to as a 'yiel d' in the semiconductor industry. A fresh report circulating in the Korean press is now claiming that executives at Samsung Foundry might have fabricated the da ta for 5nm and 4nm yields, in an effort to misplace the funds allocated by the c ompany to improve chip manufacturing efficiency. ***正在調查晶圓代工部門的造假案。***跟GG是唯二能做5奈米以下的晶圓代工廠。而評估晶圓製程的指標在半導體產業叫做良率。有新消息指出***在4奈米跟5奈米存在為了挪用母集團提供來改善良率的資金而造假良率的問題。 The report, which surfaced earlier today in Korea, comes courtesy of Infostockda ily, and it mentions the yields for Samsung's latest chip manufacturing technolo gies, which are the 5nm and the 4nm process nodes. The yield of a chip process r efers to the number of chips in a wafer that meet quality testing standards, and it is a key parameter that is evaluated by foundries through early production r uns before full scale manufacturing kicks off. 今天稍早來自韓媒Infostockdaily的報導提到了***最先進的5奈米跟4奈米製程的良率。良率是指晶圓上能通過測試標準的晶片比例，通常都是在正式量產前的試產階段評估的。 According to the Korean publication, officials at Samsung Electronics are conduc ting an investigation on the whereabouts of the funds that had been allocated to Samsung Foundry for improving its chip manufacturing process yields. This is to determine whether the figures for the yields of the 5nm and 4nm nodes were fals ified in order to create an impression that all is well at Samsung's chipmaking arm when reality would suggest otherwise. 他們指出***的官方高層正在調查用來改善良率的資金去向，好確定是不是存在良率造假的問題。畢竟現實情況是良率與標稱不符。 Samsung and the Taiwan Semiconductor Manufacturing Company (TSMC) are the only t wo in the world that are selling chip products to customers under the 5nm brandi ng. The pair are currently locked in a race to be the first to deliver 3nm produ cts to the market. ***跟GG是唯二能做5奈米以下的晶圓代工廠，而他們正在競爭誰能先搶下3奈米節點。 Infostockdaily quotes an official familiar with the matter at Samsung Electronic s stating that: "Since the delivered quantities is struggled to meet the recent foundry orde r volume, we have doubts about the yield of the non-memory process, which has wa s known to be achieved. The management consulting investigates the claims on the yield of a semiconductor foundry by former and current DS division executives. The consulting will determine whether the claims are false" Infostockdaily引述了***官方的相關人士「因為我們的產量看起來問題很大，我們不得不懷疑邏輯製程的良率。管理層正在調查當初宣稱的良率是不是真實的。」 Reports from the Korean press have already suggested that Samsung's yields for t he 4nm process were shockingly disappointing and might have touched as low as 35 % for San Diego, California chip giant Qualcomm Incorporated's flagship Snapdrag on smartphone system on chip (SoC). This figure implies that out of 100 Snapdrag on chips present on a silicon wafer, only 35 were able to clear the required qua lity control standards. 據他們指出***幫高通代工的SoC良率只有35%，也就是說晶圓上每100顆高通晶片只有35顆能達到測試標準。 These reports have also hinted that Qualcomm has chosen to rely on TSMC for its 3nm chip needs and shifted a portion of its 4nm products to the Taiwanese compan y as well. In addition to Qualcomm, Samsung also manufacturers semiconductors fo r Santa Clara, California graphics processing unit (GPU) designer NVIDIA Corpora tion. 這些報導解釋了為什麼高通把3奈米跟4奈米交給GG代工。除了高通，***也有幫老黃代工GPU 。 TSMC itself is reportedly facing yield problems with its 3nm process, which is s et to enter volume production later this year. Reports of yield fraud at Samsung are yet to be corroborated by other publications, with Infostockdaily being the first to outline the possibility of fund misappropriation. Samsung officials ha ve also stated that the investigation is routine and the situation is premature for disclosing any additional details. 不過GG也被報導預計今年量產的3奈米有良率問題，目前也沒有別的消息來源指出***有挪用資金。***官方也說現在一切都還在調查，下定論還為之過早。 5.心得/評論：***不知道是哪根筋不對，整個流程裡面能混水摸魚的地方這麼多，偏偏要挑一個一翻兩瞪眼沒辦法作弊的來唬爛。垃圾高通也貪小便宜活該被騙，35%良率真的要笑死人，還不知道是把漏電spec放多鬆才能有35%。前幾天寒流我親身體會到S888真的很適合用來暖手。老黃30系列用8奈米逃過一劫，看到高通吃屎下一代也不敢繼續用了 -- ※ 發信站: 批踢踢實業坊(ptt.cc), 來自: 223.139.52.207 (臺灣) ※ 文章網址: https://www.ptt.cc/bbs/MobileComm/M.1645778650.A.B12.html
