In the previous issue, we introduced the wafer preparation process (link). Silicon ingots and wafers Today, we will continue to discuss the manufacturing process of chips (die). This stage is the most challenging part of the chip manufacturing process. I will try to explain it in a simple and understandable way, and I hope everyone … Read more
Source: Fresh Date Classroom Original Author: Little Date Jun This article mainly introduces the process of chip manufacturing. Oxidation First, on the wafers that have been cut and polished, we need to perform an oxidation step. The purpose of oxidation is to form a protective film (oxide layer) on the fragile surface of the wafer. … Read more
