The entire semiconductor manufacturing process can consist of hundreds of steps. The ultimate goal is to get hundreds of copies of an integrated circuit on a single wafer. While we aren’t going to get into the hundreds of steps, we will take a look at some of the more integral steps in the wafer manufacturing process.
The first step in the semiconductor manufacturing process is the production of the actual wafer. The wafer is a thin, round slice of a semiconductor material, usually silicon. During this process, purified polycrystalline silicon, created from sand, is heated to a molten liquid. The wafer is then processed through a series of machines. During that time, it is ground smooth and chemically polished to a mirror-like luster.
After the wafers are processed, they are then ready to be sent to the wafer fabrication area. From there, they are used as the starting material for manufacturing integrated circuits. The fabrication process takes place in a clean room. It involves a series of principle steps described below. Typically, the fabrication process takes anywhere from 10 to 30 days to complete.
