Product Details
Hydrogen bromide, like hydrogen chloride, belongs to the family of hydrogen halides; however, its chemical properties differ due to the introduction of the bromine atom, giving it a unique niche in high-end manufacturing. In the electronics industry, hydrogen bromide’s primary application is also in semiconductors. Dry etching Link, especially for Silicon and Germanium Etching of materials. Compared to hydrogen chloride, hydrogen bromide typically exhibits a slower etching rate and... Higher selectivity This means that when etching the target material, it exhibits lower aggressiveness toward the mask layer or other underlying materials, thereby achieving finer processing with less damage—a feature that is particularly important in advanced manufacturing processes. Moreover, hydrogen bromide is an important chemical intermediate widely used in the pharmaceutical industry for synthesizing a variety of drug molecules, and in fine chemistry for producing bromine-based flame retardants, dyes, and pesticides. Its core value lies in offering etching solutions that are more selective than those provided by hydrogen chloride, as well as unique bromination reaction pathways.
