On the other hand, the process developed by Union Carbide Co., shown in Fig. 2, uses silane (SiH 4) as a source of polycrystalline silicon.As in the case of the Siemens process, Si MG is produced via metallurgical reduction of SiO 2 and C. Both Si MG and silicon tetrachloride (which is recirculated from the following step) are hydrogenated in a fluidized bed reactor to produce chlorosilanes

Thin film polycrystalline silicon carbide (poly-SiC) doubly clamped microtensile specimens were fabricated using standard micromachining processes, and precracked using microindentation. The poly-SiC had been deposited on Si wafers by atmospheric pressure chemical vapor deposition, a process which leads to residual tensile stresses in the poly-SiC thin films; we measured the residual stress

Another strategy to suppress the blistering is to incorporate carbon (C) into the film and form polycrystalline silicon carbide (poly-SiC x) films [25,26]. It not only can effectively suppress the blistering, but also promote the device photoelectrical properties with improved passivation quality and optical response in the infrared band [27,28].
