What is a silicon chip used for?What does it have to do with semiconductors.What are the components on the PCB board with silicon?
But a good silicon chip is not available. Because the bare silicon wafer is not easy to damage and difficult to connect. This is a process of binding, the so-called binding is bound to use a very fine gold wire from the silicon chip lead wire, received on the metal pipe, and then use the non-conductive plastic to bind the chip sealed. We generally see transistors, chips, etc. are packaged, you simply can not see the inside of the core. Of course is also useful in metal or ceramic chip shell, such as the two or three level of some high power tubes, military grade components etc., but because the metal and ceramic package cost is relatively high, so most of the circuit or engineering plastic package.PCB is a printed circuit board, is what we call the board. The copper wire and the welding of various components and chips. The manufacturing of printed circuit board, you should check the information bar, then I talk today what also don't want to do
However, in order to manufacture semiconductor components and integrated circuits (IC). Pure silicon wafers have to be created and then used in a variety of processes, such as etching, doping, etc., to make conductive semiconductor circuits on silicon wafers. This process can achieve the level of precision represents the level of semiconductor manufacturing processes, such as the computer's CPU is the number of microns with the manufacture of technology. Because the process is more precise, in the same size of silicon, can make a number of more circuits, that is to achieve a higher degree of integration. At the same time, because the distance between the circuit is small, the length of the wire is short, the required working voltage is lower, the power consumption can be reduced, and the operating speed can be increased.
This problem may be more profound understanding of microelectronics.I am learning communication, simply say my understandingPure silicon wafer conductivity is relatively weak. But the incorporation of trivalent impurities or pentavalent after a carrier (free electrons or holes) and semiconductors. The electrical conductivity of semiconductors and the type of doping, the concentration and process. Knowledge of semiconductor doping analog electronic circuits on the textbook.
