The basic structure of a Light Emitting Diode (LED) is an electroluminescent semiconductor device, widely used in home and industrial lighting, outdoor display, automotive and mobile applications. The LED industry is mature. Manufacturers are seeking new and innovative solutions to improve performance and reduce cost, enabling new applications. Vital Thin Film Materials (VTFM) is uniquely positioned to support this effort.
VTFMs in-house recycling and refining services guarantee stable supply with consistent quality due to tight control over the starting raw materials and subsequent sputter target production steps (VIM, HP, HIP, etc.). This creates a unique position for VTFM to support customers with a closed-loop recycling service of spent targets, thereby reducing cost of ownership. VTFM has established a target ‘leasing’ program for many metals and precious metals, based on target utilization rates or crediting accounts for the returned metal value according to daily prices, less recycling fees.
Standard LED sputter target and evaporation materials include Al, Ti, Ni, Ag, Au, Pt, W, WTi and ITO depending on the application and process.
