In this modern era, electronics relies so much on semiconductors. It is clearly evident the fact that the technology today is increasing. These materials can either be elements or compounds that can conduct or resist electricity. Unimaginable figures of modern equipments are very much dependent on using semiconductors because this class of modern equipment would not work without the benefits from the semiconductor parts. The unique capacities exhibited by these materials are quite interesting. Apart from the transferring energy, the semiconductors can control the current flow direction, produce light, and convert thermal energy. Due to their unique characteristics, the electronics industry prefers the use of these materials. Considering the current technological level of the man-made devices, the use of semiconductor technologies has become a necessity.
The Background of Semiconductor
Before semiconductor became the most important part of every electronic device, it has undergone several manufacturing processes. Certain alloys, germanium, silicon, silicon carbid, gallium arsenide, and some organic compounds are the major raw materials. These materials may be compromised by impurity, creating an extreme precision throughout the whole process of requirement. Take note that there is a wide range of uses in such components. Aside from the most popular electronic devices, it has the power to build logic gates, oscillators, microprocessors, power devices and MOSFET. Such applications include the foundation of a wide variety of analog, digital, and mixed-signal circuits. Such circuits become the individual units that make up several equipments, which makes the operations possible.
The Equipments Built By Semiconductors
As for the equipments that comprise with these components, there are numerous. Such equipment includes desktop, laptop computers, cellular phones, digital measuring devices, television, cameras, automobiles, and many more. When talking about the advanced technology, a semiconductor makes it possible to produce and generate nanocircuits, which are specialized circuits whose size are measured in the nanometer scale.
Classifications of Semiconductors
There are classifications of semiconductors. They are the Two-terminal, three-terminal, four-terminal, and multi-terminal. All of them are the existing categories. Laser diodes, photocells, LEDs, rectifier diodes, solar cells and VECSEL are examples of two-terminal devices. On the other hand, ordinary transistors, thyristors and silicon-controlled transistors are three-terminal devices. Examples of four-terminal devices is the magnetic field sensor. For multi-terminal devices, integrated circuits, charge-coupled devices, RAM, microprocessors and ROM. Without using semiconducting devices, it goes without saying that the current industrial and electrical products cannot function. The most common of such devices are diodes, transistors and sensors. Diodes are the components that enable the majority of the current to flow in one direction and not the other. When stimulated by some physical input, emission of low voltage electricity is a characteristic of sensors. Thermocouples, optical sensors and motion detectors are several variations of the sensors. On the other hand, transistors are the components that have the capacity to regulate the amount of current flowing, same goes as to what the water valves do.
To maintain the current level of technological progress that every mankind has achieved, using these components is absolutely important.
