All in all, the manufacturing of chips requires the use of many raw materials, of which silicon is the core, and other materials are selected for the specific requirements of the chip. At the same time, different manufacturing processes and design schemes also have an impact on the raw materials used.
Chips are microelectronic devices composed of a variety of raw materials, the main raw materials include: Silicon wafer, Photoresist, Mask, Metal Film, Chemical, Packaging Material, etc. These raw materials go through a series of processing and treatment before they can be composed of the final chip product.
Chip raw materials are mainly monocrystalline silicon, the nature of silicon is to do semiconductor, high-purity monocrystalline silicon is an important semiconductor material. P-type silicon semiconductor is formed by adding a trace of Group IIIA element into monocrystal silicon. A small amount of group VA element is added to form an N-type semiconductor. The P-type semiconductor and the N-type semiconductor are combined to form a p-n junction, which can be made into a solar cell.
These doped chemical elements are also raw materials for making chips, forming different types of semiconductors to meet the needs of integrated circuit components, small but very important, such as gallium arsenide doping.
