Specialized in product

Hydrogen Bromide (HBr) Gas is a highly corrosive, colorless, non-flammable gas with a pungent odor. In the electronics industry, it serves as a crucial etchant for semiconductor manufacturing, offering excellent anisotropy and precise etching control. It is particularly valued for its effectiveness in patterning silicon-based materials and high-k dielectrics, enabling the production of advanced microelectronic devices.

HBr gas is one of the key process gases in plasma etching for semiconductors. It is characterized by high etch selectivity to photoresist masks and silicon, making it indispensable for defining critical features in silicon, polysilicon, and silicon-germanium alloys, as well as for sidewall passivation to achieve vertical etch profiles.
