12 inch Silicon Wafer Prime Test Dummy Wafers
Silicon wafer is a material used for producing semiconductors, which can be found in all types of electronic devices that improve the lives of people. Silicon comes second as the most common element in the universe; it is mostly used as a semiconductor in the technology and electronic sector.
There are various methods used in silicon fabrication counting the horizontal Bridgeman method, horizontal gradient freeze method, vertical gradient freeze, vertical Bridgeman method and the Czochralski pulling method.
The Silicon wafer is the main element in integrated circuits. Simply put, integrated circuits are a composite of a variety of electronic elements that are brought together to perform a particular function.
Silicon is the key platform for semiconductor gadgets. A wafer is just but a thin slice of the semiconductor material that acts as a substratum for microelectronic devices fitted in and above the wafer.
