In semiconductor processes, electronic grade hydrogen bromide is used as a surface cleaner, etchant, dopant, and source of hydrogen atoms.

Used for diffusion, doping, dry etching and other processes in silicon semiconductor devices and integrated circuits for the electronics industry.

Mainly used as epitaxial, deposition gas, amorphous silicon carbon growth, bonding photoresist, etc., Propene is a key gas for semiconductor manufacturing.

It is mainly applied to plasma-enhanced chemical vapor deposition processes.

Mainly used in chemical vapor deposition CVD and doping process improvement, in some semiconductor process links, acetylene can also be used as a protective gas.

Mainly used for epitaxy and deposition.
