2022 Обзор отрасли производства полупроводниковых пластин
2022 Обзор отрасли полупроводниковых пластин Полупроводниковая кремниевая пластина является носителем для производства чипов, also known as silicon wafer because the raw material is silicon.After planning and management-free silicon refining, purification, monocrystalline silicon production, wafer forming and other processes, it can enter the subsequent links such as chip single-channel etching, which is the most important pre-process for chip manufacturing.The concept mainly includes: companies that develop and manufacture semiconductor wafers, silicon wafers and polished wafers.Classified by processAccording to the type of...
