Wafers 3 In 1 Machine

In electronics, a wafer (also called a slice or substrate) is a thin slice of semiconductor, such as a crystalline silicon (c-Si), used for the fabrication of integrated circuits and, in photovoltaics, to manufacture solar cells. The wafer serves as the substrate for microelectronic devices built in and upon the wafer.Wafer fabrication equipment uses mainly physical and chemical processes to create minute, multi-layer cir- cuits on round silicon wafers. While various types of equipment are used for performing these microscopic processes, most of these products can be grouped into several broad categories.
