Complementary metal oxide

Complementary metal-oxide-semiconductor (CMOS) complementary semiconductors (CMOS), like CCDs, are light-emitting semiconductors that record light in a scanner. At present, CMOS photosensitive devices are mainly applied to a small number of business card scanners and document scanners. The manufacturing technology of CMOS is not different from general computer chips. It is mainly made of semiconductors made of silicon and germanium so that they can coexist on the CMOS with N (with & nash; electricity) and P (with + electricity) levels. For semiconductors, the currents produced by these two complementary effects can be recorded and interpreted by the processing chip as images. However, the disadvantage of CMOS is that it is prone to noise. This is mainly due to the fact that early designs made CMOS overheated due to current changes when dealing with rapidly changing images.
