What is Silicon Wafer?
A siltron wafer, which is the fundamental material of semiconductor device manufacturing today, is consisted of highly purified silicon.

The raw material of silicon is called Silica(SiO2) and is one of the core elements of the mineral world, making up 27.8% of the earth's crust.

A silicon wafer made of silicon has a wide Energy Band Gap(1.2eV) and can operate at high temperature.

A recently SEMI published report, Silicon Reclaim Wafer Characterization Summary, provides details on the 2007 silicon wafer reclaim for the semiconductor market and provides a forecast to 2010. Seven regions of the world are covered in this report including North America, Japan, Europe, Korea, Taiwan, China, and Rest of World (ROW). Market estimates for reclaim wafers include semiconductor applications including equipment and IC manufacturing markets.

- Japan quake damage cuts silicon wafer supply
Supplies of silicon wafers used to make semiconductor chips could start to run short in May, following the suspension of operations at two major plants hit by the earthquake

TOKYO, March 25 : Supplies of silicon wafers used to make semiconductor chips could start to run short in May, following the suspension of operations at two major plants hit by the March 11 earthquake that devastated large areas of northern Japan.
