Silicon Wafer Production and Specifications

After dicing, the wafers are lapped on both sides in order to i) remove the surface silicon which has been cracked or otherwise damaged by the slicing process (e.g. grooves by the wire saw) and ii) thinned to the desired wafer thickness. Several wafers at a time are lapped in between two counter-rotating pads by a slurry consisting of e.g. Al 2 O 3

Wafer (electronics) - Wikipedia

Wafers are formed of highly pure, nearly defect-free single crystalline material, with a purity of 99.9999999% (9N) or higher. One process for forming crystalline wafers is known as the Czochralski method, invented by Polish chemist Jan Czochralski. In this process, a cylindrical ingot of high purity monocrystalline semiconductor, such as silicon or germanium, called a boule, is formed by pulling a seed crystal from a melt. D

Silicon Wafer Manufacturing Process - Silicon Valley ...

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.

Chemical vapor deposition (CVD) oxide is a linear growth process where a precursor gas deposits a thin film onto a wafer in a reactor. The growth process is low temperature and has a much higher growth rate when compared to thermal oxide. It also produces much thinner silicon dioxide layers because the film is deposted, rather than grown.
