What is a Wafer in VLSI

Posted on February 27, 2023June 17, 2025 By vlsifacts 1 Comment on What is a Wafer in VLSI

A wafer is a thin slice of semiconductor material, typically made of silicon, that serves as the substrate for the fabrication of integrated circuits in the field of VLSI. During the fabrication process, the wafer undergoes a series of processes such as doping, lithography, etching, and deposition to create the desired patterns and structures for…
