Description

Antimonous Hydride, also known as stibine, is a highly volatile, gaseous inorganic compound of significant industrial interest. Its primary value lies in its role as a critical precursor in the semiconductor and electronics manufacturing sectors for the deposition of antimony-containing thin films. This product is essential for industries involved in advanced materials science, doping processes, and specialized chemical synthesis. We supply high-purity Antimonous Hydride CAS NO 7803-52-3 to meet the stringent demands of global research and high-tech production.

Application

• Semiconductor Manufacturing: Used in chemical vapor deposition (CVD) and metalorganic chemical vapor deposition (MOCVD) processes for doping silicon and depositing III-V compound semiconductors.
• Thin Film Deposition: Serves as a key precursor for creating antimonide-based thin films used in infrared detectors, lasers, and high-speed transistors.
• Chemical Synthesis: Acts as a specialized reducing agent and antimony source in the synthesis of novel organometallic compounds and advanced materials.
• Fumigant Production: Historically used in the formulation of certain fumigants, though modern use is highly regulated and specialized.
• Research & Development: Employed in academic and industrial laboratories for studying the properties of hydrides and developing new electronic materials.
