Semicera Energy Technology Co., Ltd. is a leading supplier specializing in wafer and advanced semiconductor consumables. We are dedicated to providing high-quality, reliable, and innovative products to semiconductor manufacturing, photovoltaic industry and other related fields.Our product line includes SiC/TaC coated graphite products and ceramic products, encompassing various materials such as silicon carbide, silicon nitride, and aluminum oxide and etc.At present,we are the only manufacturer to provide purity 99.9999% SiC coating and 99.9% recrystallized silicon carbide. The max SiC coating length we can do 2640mm.
GaAs substrates are divided into conductive and semi-insulating, which are widely used in laser (LD), semiconductor light-emitting diode (LED), near-infrared laser, quantum well high-power laser and high-efficiency solar panels. HEMT and HBT chips for radar, microwave, millimeter wave or ultra-high speed computers and optical communications; Radio frequency devices for wireless communication, 4G, 5G, satellite communication, WLAN.
Recently, gallium arsenide substrates have also made great progress in mini-LED, Micro-LED, and red LED, and are widely used in AR/VR wearable devices.
