China’s domestic lithography sector is entering another phase of internal restructuring, with AMIES Technology consolidating industrial assets originally spun out from Shanghai Micro Electronics Equipment (Group) Co., Ltd. (SMEE). Corporate filings and Shanghai Securities News show that AMIES has acquired 100% of Shanghai Weiyao Industrial Co. for CNY228.5 million (US$32.5 million), replacing SMEE as the sole shareholder. The transaction completes SMEE’s exit from Weiyao while keeping the asset within the SMEE-origin corporate structure.
