Crystal substrates are foundational materials characterized by their highly ordered crystal structures. They are extensively used in the manufacturing of semiconductor devices, optoelectronic equipment, and high-performance microelectronic systems. Serving as both electrical platforms and mechanical supports, crystal substrates not only determine the electrical performance of devices but also influence their structural stability and operational reliability.
Transistors and integrated circuits are made on the surface of a semiconductor chip, and the semiconductor chip here is the substrate (chip). The semiconductor substrate not only plays a role in electrical performance but also plays a role in mechanical support. Chemical substrates show broad application prospects in short-wavelength light-emitting diodes, lasers, and ultraviolet detectors, as well as high-temperature microelectronic devices; for environmental protection, they are also very suitable for environmentally friendly material systems.
