1,1947 65438+In February, a research group composed of shockley, Bardeen and bratton of Bell Laboratories developed a point contact germanium transistor. The appearance of transistor is an important invention in the 20th century and a pioneer of microelectronics revolution.
In 2.20 16, a team of Lawrence Berkeley National Laboratory broke the physical limit and reduced the most advanced transistor manufacturing process from 14nm to 1nm, thus completing a major breakthrough in the field of computing technology.
Extended data:
1, transistor, whose real name is semiconductor triode, is a semiconductor device with two PN junctions inside and usually three extraction electrodes outside. It has the function of amplifying and switching electrical signals and is widely used.
2. Triode is a semiconductor device for controlling current. Its function is to amplify a weak signal into an electrical signal with a large amplitude, and it is also used as a contactless switch.
3. Transistors promoted and brought about the "solid-state revolution", which in turn promoted the global semiconductor electronics industry. Because transistors completely changed the structure of electronic circuits, integrated circuits and large-scale integrated circuits came into being.
4. The transistor has the function of current amplification, the essence of which is that the transistor can control the big change of collector current with the small change of base current, which is the most basic and important characteristic of the transistor.
