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. Not just any sand scraped off the beach can be used ...

After the wafers have been sliced, the lapping process begins. Lapping the wafer removes saw marks and surface defects from the front and backside of the wafer. It also thins the wafer and helps to relieve stress accumulated in the wafer from the slicing process. After lapping the silicon wafers, they go through an etching and cleaning process.

· The semiconductor manufacturing process starts conceptually from raw sand which is purified into melted silicon. The melted silicon is shaped into high purity silicon ingots, which are then cut into thin wafers. The wafers are polished to mirror smoothness, then carefully cleaned, covered with a protective oxide coating, then with photoresist material, and finally exposed to EUV light from a ...

Steps to Make Silicon Wafers. When we talk about what is silicon wafer made of, we are talking about the thin membrane that is used to hold the wafer intact until the time it's used in electronics. The silicon, or glass, is very pure. When device production is first started, the silicon contains a normal impurity level of less than one percent.
