Analysis of Semiconductor 8 Major Processes and Leading Companies
Semiconductors are the core components of electronic devices, and their manufacturing process requires extreme precision and advanced technology. The production of semiconductor chips involves Wafer Manufacturing → Oxidation → Photolithography → Etching → Ion Implantation → Deposition → Metallization → Packaging & Testing in eight major steps. This article provides an in-depth analysis of the principles, latest trends, and competitive landscape of these eight major semiconductor processes. 1. Wafer Manufacturing Process Overview This process involves producing silicon wafers, which serve as the foundation of semiconductor chips. Raw Material: High-Purity Silicon (Si, 99.9999999%) Czochralski (CZ) Method : Silicon is melted and grown into a monocrystalline ingot Slicing the Ingot to form wafers Surface polishing and cleaning to remove impurities Wafer size : Currently, 300mm (12-inch) wafers are dominant, with discussions on 450mm wafer development Key Companies & Marke...
