Semiconductor manufacturing is a complex process that involves the use of various techniques to modify the properties of semiconductor materials and create semiconductor devices. Two important concepts in semiconductor manufacturing are doping and diffusion, which play a crucial role in determining the performance and functionality of semiconductor devices. In this article, we will delve into the concepts of doping and diffusion, their significance in semiconductor manufacturing, and the advancements made in these processes.
Doping is the process of intentionally introducing impurities into a semiconductor material to alter its electrical properties. This is achieved by adding specific elements, known as dopants, to the semiconductor material.
