What are the inner semiconductors?
Inner semiconductors are a pure form of elements that usually have four valence electrons. A special process can be done to make internal semiconductors negative (n) type or positive (p) type semiconductor. The use of p and n-type semiconductors include bipolar connecting transistors (BJT), field effect transistors (FET) and rectifiers controlled by silicon (SCR). Both silicon and Germanium are elements of four valence. Silicon is a common material for semiconductors, although Germanium is also used for high -frequency applications. The difference between silicon and germanium is that the decrease in the front voltage in Germanium is about 0.2 V) compared to 0.7 V V in silicon.
In the production of internal semiconductors, silicon melts at a very high temperature in an inert gas or vacuum. Theeral melted material looks very much like molten glass. Through a process called cultivation, a rotating grower slowly attracts the molten silicon into the inner silicon material in the form of a rod by about a few PAlci on average.
Inner silicon materials, called undeveloped semiconductors, internal semiconductors (I) or internal semiconductors, are little useful for the electronic industry. The useful form of silicon is the result of adding special elements known as dopants, in a process called doping, where they add dopants such as phosphorus or boron, while silicon is still melted. When the phosphorus is added to silicon, the extra electron makes a nemkerk -type semiconductor. Special techniques such as the surface acoustic wool (SAW) are used to cut very hard material, such as silicon doped phosphorus.
Silicone wafers generated by slicing can be deployed on the X -axis and then on the Y axis, resulting in a huge number of Nemis semiconductors.Masonry is also produced and are ready for the assembly process. At this point, the inner semiconductors were transformed into external semiconductors. The simplest set of type P type is a positive negative (P-N) junction known as a diode that is a one-way valve. The P-N connection, which was generated by contact of the N and P-Type semiconductor, now has a special characteristic known as one-way conductivity.
