Microchip fabrication is a complex and intricate process that involves the creation of tiny electronic circuits on a semiconductor material, typically silicon. The process is crucial for the production of modern electronics, including computers, smartphones, and other devices that have become an integral part of our daily lives. In this blog post, we will provide an overview of microchip fabrication, its history, and the various steps involved in the process.
A seed crystal is dipped into molten silicon and slowly pulled out, forming a large cylindrical crystal called an ingot . microchip fabrication pdf
Packaging and testing are final steps in microchip fabrication. Packaging involves encapsulating the microchip in a protective casing, while testing involves verifying the functionality of the microchip. Microchip fabrication is a complex and intricate process
Lithography and patterning are critical steps in microchip fabrication. Lithography involves creating patterns on the wafer using light, while patterning involves transferring the patterns onto the wafer. A seed crystal is dipped into molten silicon
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.
