Description

HCDS is used to grow thin films of Si, SiO2, SiC, Si3N4 by chemical vapor deposition. The advantage to using HCDS is that it can be used at low temperatures; powerful deoxygenating agent; reducing agent; fiber optics, solar energy products; aiding ALD process.

HCDS is predominantly used in semiconductor and solar manufacturing industries. Through chemical vapor deposition (CVD) and atomic layer deposition (ALD) processes, HCDS is used as a precursor for low temperature deposition of thin layers of SiN, epitaxial Si and SiON used in semiconductor manufacturing.

HCDS is used to produce amorphous silicon thin films. HCDS can be utilized as a chemical diffusion barrier to create gate spacers for dynamic random access memory (DRAM) devices.

Sometimes used in the pharmaceutical industry, for the reduction of phosphine oxides.
