Silicon(IV) Iodide (I4Si) Powder Applications:

Silicon(IV) Iodide (I4Si) Powder is used as a precursor to prepare Silicon(IV) amides. It finds application in the manufacture and etching of Silicon(IV) 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.
