SILICON (IV) IODIDE

Description

Silicon Iodide is the iodide of silicon. It is a precursor to silicon amide. It is also applied in the manufacture and etching of silicon in microelectronics. Selective area regrowth of silicon-doped GaAs has been successfully achieved by chemical beam epitaxy (CBE) on dry etched trench structures. Silicon tetraiodide is useful for the above process in abrupt to manipulate metal-semiconductor field effect transistor (MESFET) and heterostructure field effect transistor (HFET). Silicon iodide can also be reduced as the source to form pure silicon and hydrogen iodide.
