Each freshcut silicon wafer is less than 200 microns thick – similar to a heavy piece of paper. These wafers must be carefully handled, inspected and cleaned before further processing. The next step is to reduce the reflectivity of the wafer from about 30% to 10% through a chemical surface texturing process that creates tiny pyramids on the wafer's surface.

Get Price1. Semiconductor wafers are made of silicon which is the secondmost common element on the Earth (just after oxygen) and it's the seventhmost common element in the entire universe. 2. As the sand used to produce the semiconductor wafers has to be a very clean, most of the sand used for these processes is shipped from the beaches of Australia.
Get PriceAnswer (1 of 3): There are 3 major steps in this process: 1. Getting the raw material, high purity silicon, used to make chips First one must refine silicon from quartz or silicon dioxide. Sand is basically quartz or silica (both are the same mineral SiO_2). See: Marko Sokolich's answer to .
