2012/3/8· The wafers were initially cleaned in piranha (H 2 SO 4:H 2 O 2 in the ratio of 2:1) at 120 C for 20 minutes and rinsed in DI water. The native silicon oxide layer was then removed by immersing the wafers in a classical BOE solution for 30 seconds.
Silicon Carbide is a synthetic electric furnace products, crystalline silicon carbide exits in a low temperature form (cubic) and high temperature form (hexagonal). The basic materials for production of silicon carbide are high purity quartz sand, petroleum coke thoroughly mixed and charged into furnace.
Appliion note: Analyse silicon carbide (SiC) with the inVia Raman microscope The properties of silicon carbide are highly dependent on its crystal structure (it can exist in many polytypes), on the quality of the crystal, and on the nuer and types of defects present.
Silicon carbide ceramics with little or no grain boundary impurities maintain their strength to very high temperatures, approaching 1600 C with no strength loss. Chemical purity, resistance to chemical attack at temperature, and strength retention at high temperatures has made this material very popular as wafer tray supports and paddles in semiconductor furnaces.
