Product Description

Silicon Wafer
Silicon single crystals are commonly used as substrates for 3-5 μm mid-wave infrared optical windows and filters. The processing of micrometer-scale optical silicon wafers encompasses various stages such as material growth, cutting, polishing, coating, and dicing. The quality, delivery time, and price are strictly controlled throughout these processes.

A silicon wafer is a crucial material for fabricating integrated circuits. Through photolithography, ion implantation, and other techniques, integrated circuits and various semiconductor devices can be manufactured on silicon wafers. Characterized by high purity, high density, and large scale, silicon wafers are sheet-like objects made of silicon.   

Single-crystal silicon is a single crystal form of silicon, a relatively active non-metal element with a nearly perfect lattice structure. It plays a significant role in enhancing the performance of integrated circuits. Larger diameters allow for the fabrication of more integrated circuits on a single wafer, resulting in higher manufacturing efficiency. This is crucial for producing integrated circuits and semiconductor devices with complex circuitry.
