General description

Dichlorosilane (DCS) is a halogenated silicon based precursor that facilitates the growth of a variety of silane based films such as silicon oxide, silicon nitride, silicon carbide, and epitaxial growth of silica.

Application

DCS is widely used in the synthesis of a variety of silicon-based materials, which find applications in the development of organic electronics based devices, including OFETs, MEMS, NEMS, MOSFETS, and lithium-ion batteries.
