Product Description
1.what is silicon wafers and it's application:
A silicon wafer is a material essential for manufacturing semiconductors, which are found in all kinds of electronic devices that enrich our lives.
Silicon wafer is the most common material and widely used for a varity of high-tech industries, including integrated circuits, detector or sensor device, MEMS fabrication, opto-electronic components, and solar cells.
Silicon wafer is a very thin round disk cut from high-purity silicon. A round silicon ingot is sliced to thicknesses of approximately 1mm. The surfaces of the resulting disk are polished carefully, then it is cleaned, resulting in the completed wafer. Silicon wafers are made from high-purity silicon, and are the material of semiconductor devices. These wafers can also be fabricated with a SEMI notch or one or two SEMI flats.
2. Manufacturing a Silicon Wafer
Growing a silicon ingot can take anywhere from one week to one month, depending on many factors, including size, quality and the specification. More than 75% of all single crystal silicon wafers grow via the Czochralski (CZ) method.
