Quais são os materiais do chip?

The main material of the chip is silicon. Silicon is a semiconductor material with excellent electrical and mechanical properties, making it an ideal material for making chips. High-purity single-crystal silicon can be doped with different elements to form p-type silicon and n-type silicon. These two types of semiconductors are combined to form a pn junction, which is widely used in various electronic devices, including diodes, triodes, thyristors, field-effect transistors, and various integrated circuits. In addition, in addition to silicon, other semiconductor materials are also used in chip manufacturing, such as gallium arsenide and germanium. Gallium arsenide has a high electron mobilidade e é frequentemente usada em dispositivos eletrônicos de alta velocidade; while germanium is mainly used in specific radio frequency and microwave devices. In recent years, researchers have also been exploring new semiconductor materials, such as graphene, which exhibits controllable semiconductor properties after epitaxial growth on silicon carbide wafers, with an electron mobility of up to 10 times that of silicon, and significantly improved computing speed and energy eficiência .
