Semiconductors are materials which have monumental impact on human life. In every device that we use, semiconductors can be found everywhere – in microprocessor ships or transistors or any essential device which we used in our everyday life. In the semiconductor manufacturing industry there are several big players. It has become a multi-billion dollar industry today. In our day-to-day life we use lot of such appliances or products which have semiconductors as his or her main component – from microwave to microprocessor chips to transistors to computers. In computers that are life to many of us have these semiconductors at their heart. Most of the semiconductors were created from silicon, that’s why silicon is soul from a computer.

Amongst all semiconductor manufacturing devices, diode will be the simplest one. It is a principal part of all semiconductors which are found in the fabless engineering industry or another industry. The most commonly designed components like ASIC designs, integrated circuits and microprocessor production, everywhere silicon could be the major ingredient. Another important component is germanium which can be specifically utilized in transistors and various other electronic devices. It is employed in various industries including fiber optics and infrared optics. It is also used in polarization catalysts, solar cell applications etc. Another very popular semiconductor is Gallium arsenide. It is a III/ V semiconductor and it is extensively utilized in the manufacturing of devices like microwave frequency integrated circuits, infrared light-emitting diodes, monolithic microwave integrated circuits, solar cells, laser diodes, plus the creation of optical windows.

While developing the silicon semiconductor devices, fabrication is really a major process. It involves various important steps. Crystal preparation could be the first step which initiates the task. In this process a single crystal of silicon is evolved into an excellent cylindrical shape. Then SiC Schottky diodes is done where solid cylinder of silicon is cut which has a diamond saw blade uniformly. Then thin film generation is conducted where physical or electrical isolation between two adjacent layers is or wafer is prepared for doping and lithography stages. Here Lithography is often a process where patterns on materials are engraved. Then a major step is carried out where high precision flat metal parts are designed, that’s also referred to as chemical milling. Furthermore, doping is conducted where we add impurities into an extremely pure semiconductor. This process aims to modulate the electrical properties of a semiconductor. Finally, metallization is conducted where material is treated and combined which has a metal. This completes the process.
