It is probable that most people have come across and even used silicon wafer in their day to day lives. It may not have been deliberate; however, for people who have used devices such as computers and smartphone, they have certainly used this equipment.
Silicon Wafer! What is it?
Prime-grade silicon substrate is a material used for producing semiconductors, which can be found in all types of electronic devices that perks up the lives of people. Silicon comes second as the most common element in the universe; it is mostly used as a semi-conductor in the technology and electronic sector.
Most individual have had the opportunity to encounter a real silicon wafer in their life. The super-flat desk is refined to a mirror-like surface. It is also made of subtle-surface irregularities which make it the flattest object globally.
It is also extremely clean, free of pollutions and micro-particles, qualities that are essential in making it the perfect substrate materials of the contemporary semi-conductors. There are various methods utilized in silicon fabrications counting the horizontal gradient freeze process, vertical Bridgeman method and the pulling method.
All through the growth process dopants can be included to amend the purity of the silicon wafer depending on its manufacturing purpose. The pollutants can alter silicon electronic properties which are essential depending on the reason of its production.
Some of the silicon dopants that can be added throughout the growth procedure include aluminium, boron, nitrogen, indium, and gallium. A semi-conductor can be regarded as either deteriorates depending on the level the silicon wafer was, when the dopants were added. Visit Alpha Nanotech to obtain supreme quality research material.
