Semiconductor processes are a critical part of modern electronics. They are used to create the transistors and integrated circuits (ICs) that power everything from smartphones to cars to medical devices. Understanding semiconductor processes is essential for anyone who wants to work in the electronics industry.
What is Semiconductor Process?
Semiconductor process is the sequence of steps used to create transistors and ICs. The process begins with a silicon wafer, which is a thin slice of silicon crystal. The wafer is then coated with a layer of oxide, which is used to protect the silicon from contamination. Next, a layer of photoresist is applied to the wafer. The photoresist is then exposed to ultraviolet light, which hardens the exposed areas. The unexposed areas are then removed, leaving a pattern of oxide on the wafer. This pattern is used to create the transistors and ICs.
