Description

Tetrakis(Dimethylamino)Tin CAS NO 1066-78-0 is a highly volatile organotin compound that serves as a versatile precursor in advanced materials synthesis. Its significance lies in its role as a volatile, reactive source of tin for chemical vapor deposition (CVD) and atomic layer deposition (ALD) processes, enabling the creation of high-purity thin films. This product is essential for manufacturers and R&D facilities in the semiconductor, electronics, and specialty glass coating industries seeking precise and efficient tin oxide deposition.

Application

• Precursor for Tin Oxide (SnO2) thin film deposition via Chemical Vapor Deposition (CVD) and Atomic Layer Deposition (ALD).
• Manufacturing of transparent conductive oxides (TCOs) for touch screens, flat-panel displays, and solar cells.
• Production of gas sensor materials, where tin oxide films are used for detecting various gases.
• Catalyst and reagent in specialized organic synthesis and polymer chemistry.
• Surface coating applications for anti-reflective and low-emissivity (Low-E) glass.
• Research and development of next-generation electronic and optoelectronic devices.
