How is silicon grown

WebIn 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. It undergoes many microfabrication … WebOxide growth appears to be faster on (111) oriented silicon when compared to (100) oriented silicon. In fact, in [ 122] it is shown that the (111) and (100) orientations represent the upper and lower bound for oxidation rates, respectively. All other silicon orientations lie between these extrema.
