Samsung Electronics Vice Chairman Jay Y. Lee (second from right) looks at an EUV machine during his tour of ASML's plant in October 2020 Samsung Electronics' de facto leader Jay Y. Lee is heading to the Netherlands next week to visit ASML Holding NV, the world's only producer of extreme ultraviolet light (EUV) scanners, key in producing advanced chips.The Netherlands is the first destination for Lee's business trip, about two weeks after the parent Samsung Group unveiled its largest-ever, five-year investment plan of 450 trillion won ($355 billion), larger than its $400 billion in assets. His trip scheduled for June 7 to 18 also comes shortly after the world’s top memory chipmaker replaced about 10 higher-ranking executives in the semiconductor division on June 2 to hold them accountable for the lower-than-expected yield of its new mobile application processor, the so-called brain of a smartphone.On the same day, Lee’s legal representative notified the Seoul Central District Court of his business trip in the following two weeks to postpone a hearing over his alleged involvement in a controversial merger between Samsung C&T Corp., the group's de facto holding company and Cheil Industries Inc. back in 2015.Responding to a judge asking “if the trip to the Netherlands is to discuss the supply of EUV scanners,” Lee’s attorney answered in the affirmative.The court approved postponing his hearing.It will be Lee’s second official visit to ASML headquarters in less than two years. Back in 2020, he toured the Dutch company's plant to discuss the supply of the lithography machine. Samsung Electronics' Lee (second from left) at an ASML plant in the Netherlands in October 2020 PREREQUISITE FOR BOOSTING CHIP PRODUCTIONEUV scanners can draw more elaborate and detailed patterns on semiconductor wafers, with short wavelengths equivalent to one-14th of conventional argon fluoride (ArF) technology. The lithography machine also simplifies the chip manufacturing process by cutting the number of photolithography processes required to create fine circuits.But its supply is limited to about 40 units per year since it takes two years to produce one scanner, while costing 200 billion to 300 billion won ($160 million-$240 million) per unit. Further, the halted production of optical lenses by Carl Zeiss due to supply chain disruptions further delayed the production of EUV scanners. ASML relies on the German supplier for the core component for EUV lithography machines.Amid the prolonged chip shortage, chipmakers around the world are competing to secure EUV scanners to expand their production lines. The world’s largest foundry maker Taiwan Semiconductor Manufacturing Co. (TSMC) has more than 100 EUV scanners. But Samsung has only 15 units of the lithography machine, although it plans to overtake TSMC by 2030.“To draw up plans on production lines, securing the relative equipment should come first,” said an industry insider.“In order to compete with TSMC, Samsung needs to win in the competition to procure EUV scanners.” In particular, Samsung needs to sign a EUV scanner supply deal within the year for its second foundry plant to be built in Taylor, Texas. The plant is poised to be operational in the second half of 2024. Samsung Electronics' Exynos chips REPLACEMENT OF CHIP EXECUTIVESOn Thursday, Samsung undertook an unexpected personnel reshuffle, involving 20 employees. Notably, it replaced 10 executives, including the flash chip development chief and the foundry business head.The reshuffle is related to the world’s largest smartphone brand’s mobile application processor chip under development. The chip, dubbed Exynos, was supposed to be used for its latest handset model, Galaxy S22, early this year.But its low yield forced Samsung to turn to Qualcomm’s Snapdragon processors for the Galaxy S22 model, except for the handsets shipped to Europe. The mishap was a hard lesson for Samsung that even superior design doesn't work without an advanced process system and pushed the company to focus on upgrading its chip design and process systems in the second half of this year, according to industry watchers.Also, Lee's meeting with visiting Intel Corp. Chief Executive Pat Gelsinger early this week is expected to present a new opportunity for Samsung, they said. By Shin-Young Park and Ji-Eun Jungnyusos@hankyung.comYeonhee Kim edited this article.
