美光簽署意向書收購銅鑼廠區 並與力積電展開策略合作關係
本次收購將新增約 30萬平方英尺的記憶體無塵室空間
美光科技（Nasdaq: MU）和力積電簽署獨家意向書（Letter of Intent, LOI），將以總價 18 億美元現金收購力積電位於台灣苗栗縣銅鑼的 P5 晶圓廠。此收購案包含一座現有300mm （12 英吋） 晶圓廠無塵室，面積約為30萬平方英尺，將進一步強化美光的定位，以因應全球對記憶體解決方案日益增長的需求。此意向書旨在建立美光與力積電在美光DRAM晶圓後段組裝製程（post-wafer assembly processing）的長期合作關係，並協助力積電精進其既有利基型 DRAM 產品線。
美光全球營運執行副總裁Manish Bhatia 表示：「此次策略性收購現有前段製程無塵室，將與美光目前在台灣的營運互補，使我們提升產能，在需求持續超越供給的市場中更好地服務客戶。銅鑼廠區與美光台中廠區相鄰，也將促進我們在台灣營運的整體綜效。」
該交易預計將於 2026 年曆年第二季完成，並需在完成協議簽署及取得必要的監管核准後進行。交易完成後，美光將取得力積電銅鑼廠區 P5 晶圓廠的所有權，並將分階段導入設備，逐步提升 DRAM 產能 ; 力積電則將於特定期間內轉移銅鑼的營運。美光預期，此收購案將自 2027 年下半年起，為其 DRAM 晶圓產能帶來顯著貢獻。
此項收購與美光持續推動的全球擴產計畫相輔相成，展現美光積極投資以滿足客戶長期需求的決心。
Micron Signs Letter of Intent to Purchase Tongluo Site, Begin Strategic Partnership with PSMC
Acquisition to add 300,000 square feet of memory cleanroom space
Micron Technology, Inc. (Nasdaq: MU) has signed an exclusive Letter of Intent (LOI) to acquire Powerchip Semiconductor Manufacturing Corporation’s (PSMC) P5 fabrication site in Tongluo, Miaoli County, Taiwan, for total cash consideration of US$1.8 billion. The acquisition includes an existing 300mm fab cleanroom of 300,000 square feet and will further position Micron to address growing global demand for memory solutions. The LOI also aims to establish a long-term relationship between Micron and PSMC for Micron’s post-wafer assembly processing and to support PSMC in its legacy DRAM portfolio.
“This strategic acquisition of an existing cleanroom complements our current Taiwan operations and will enable Micron to increase production and better serve our customers in a market where demand continues to outpace supply,” said Manish Bhatia, executive vice president of global operations at Micron Technology. “The Tongluo fab’s close proximity to Micron’s Taichung site will enable synergies across our Taiwan operations.”
The transaction is anticipated to close by calendar Q2 2026, following the closure of deal agreements and the required regulatory approvals. Upon closing the transaction, Micron will assume ownership and control of the P5 site to equip and ramp up DRAM production in phases, with PSMC relocating its Tongluo operations over a specific time. Micron expects this acquisition to contribute to meaningful DRAM wafer output beginning in the second half of calendar 2027.
This acquisition complements Micron’s ongoing global expansion plans as the company invests to meet long-term demand from its customers.
