The most critical step. A light-sensitive liquid called photoresist is applied to the wafer. Ultraviolet (UV) light is then shone through a mask (a blueprint of the circuit), transferring the pattern onto the wafer.

This ingot is sliced into thin discs called wafers (typically 200mm or 300mm in diameter), which are polished to a mirror-like finish. 2. Core Fabrication Steps (The "Front-End") microchip fabrication pdf

A seed crystal is dipped into molten silicon and slowly pulled out, forming a large cylindrical crystal called an ingot . The most critical step

Microchip fabrication is a complex and fascinating process that has revolutionized the electronics industry. The process involves several steps, including design, mask creation, wafer preparation, lithography, etching, doping, metallization, and packaging. Despite the challenges faced by microchip manufacturers, advances in microchip fabrication have led to the development of smaller, faster, and more powerful microchips. This ingot is sliced into thin discs called
