Facts About Silicon Wafers

While most people use silicon wafers every day, they may not know it. It is incredibly present in the world, actually being the second most prevalent mineral in the world and the seventh most prevalent in the known universe. It is widely used as a material acting as a semiconductor and is mostly used in the industries of technology and electronics.

There are many different methods of fabricating the silicon including two different freeze gradient methods, two different Bridgeman methods and a method known as Czochralski pulling. During any of the growth processes, the purity can be changed to accommodate the intended purpose by adding substances known as dopants. The reason impurities are intentionally added is that they change the electrical current of the silicon. The most popular of the impurities are gallium, boron, aluminum, and indium. The higher the level of doping, the more conductive the thin silicon wafers will be. Silicon which is lightly doped is known as extrinsic whereas silicon that is more heavily doped is known as degenerate.

Thin silicon wafers are so important because they are responsible for powering the electronic devices that are in use today. Everything from microwaves to computers to automobile electronics use some form of silicon to function as a semiconductor. While there have been other substances which have been tested to function as a semiconductor, historically speaking, they have not lasted or been put in widespread use because silicon is by far the most stable.

As you can see, there are many wonderful uses for thin silicon wafers . Their importance in the electronics industry cannot be overstated and they continue to be modified and streamlined so as to achieve better and better functionality. When it comes to the usage of silicon as a manufacturing giant, there is no end in sight.
