Week In Review: Semiconductor Manufacturing, Test


GlobalFoundries filed suit in U.S. District Court in New York against IBM, accusing it of unlawfully disclosing IP and trade secrets to IBM partners, including Intel and Rapidus, potentially receiving hundreds of millions of dollars in licensing income and other benefits. The European Union released a €43 billion ($47 billion) plan for jumpstarting its semiconductor manufacturing industry,... » read more

Mixed Outlook For Silicon Wafers


Silicon wafers are a fundamental part of the semiconductor business. Every chipmaker needs to buy them in one size or another, such as 200mm, 300mm and others. Silicon wafer vendors produce and sell bare or raw silicon wafers to chipmakers, who in turn process them into chips. So what’s in store for the silicon wafer market? Sungho Yoon, senior research manager at SEMI, sat down with Se... » read more
