Description

Disilane is a highly reactive, gaseous silicon hydride compound with the molecular formula Si₂H₆. It serves as a critical precursor in the deposition of high-purity silicon-based thin films, enabling precise control over material properties. This compound is essential for manufacturers in the semiconductor and advanced materials sectors, particularly for applications in chemical vapor deposition (CVD) and atomic layer deposition (ALD) processes.

Application

• Semiconductor Manufacturing: As a silicon source for the chemical vapor deposition (CVD) of silicon, silicon carbide (SiC), or silicon-germanium (SiGe) thin films.
• Photovoltaics: Used in the production of amorphous or microcrystalline silicon layers for high-efficiency solar cells.
• Advanced Coatings: Enables the creation of hard, wear-resistant silicon-based coatings on various substrates.
• Optoelectronics: A key precursor for depositing silicon-containing layers in light-emitting diodes (LEDs) and other optoelectronic devices.
• Research & Development: Employed in laboratories for synthesizing novel silicon compounds and materials research.
• Nanotechnology: Facilitates the controlled growth of silicon nanowires and other nanostructures.

Quality Control

Our Disilane is produced and handled under stringent quality protocols to ensure high purity and batch-to-batch consistency, meeting the exacting requirements of the electronics industry. Each lot is analyzed using advanced gas chromatography (GC) and mass spectrometry (MS) techniques. A comprehensive Certificate of Analysis (COA) detailing purity, impurity profiles, and moisture content is provided with every shipment.

Storage

Preserve in a tightly closed, specially designed cylinder under an inert atmosphere (e.g., nitrogen or argon) in a cool, well-ventilated area, protected from light. Due to its highly volatile and gaseous nature, store away from heat, sparks, open flames, and oxidizing agents. The container temperature should not exceed 30°C (86°F).
