Semiconductors: The Groundwork of Electronic Devices?

When talking about material that embraces the art of conductivity, it is the semiconductor. In fact, the electric conductivity in these materials is due to the fact that flowing electrons which are the magnitude between that of an insulator or the conductor. All of the devices that are made from the semiconductor material are the foundation of modern electronic which includes computers, radio, home appliances and all electronic devices. The Semiconductors, which are found in the transistors and microprocessor chips has made a huge impact in our world today.

Know the Basics

Silicon is the material used as a semiconductor in the microprocessor transistor and chips. Have you heard about ‘Silicon valley’ or ‘Silicon economy’? These two places were both derived from the world silicon, which are the heart of any electronic devices. Silicon is a very common element in sand and quartz. Scientifically speaking, if you look at silicon in the scientific way, for example, in the periodic chart you will find silicon has aluminum on one side, on the top, Carbon and below it is the germanium. These 3 material Germanium, Silicon and Carbon have a unique property in their structure of electrons where each has 4 electrons in the outer orbit, and having electrical conductivity, which is greater compared to that of insulators but are less than good conductors, and are used especially as a base material for electronic devices and computer chips.


When it comes to a very good conductor of electricity, metals are the very reason on why they usually have ‘free electrons’ that can easily move between electricity and atoms involve the flow of electrons. Silicon crystals, on the other hand, look metallic, but take note that it is not metal. The silicon’s outer electrons are involved in perfect covalent bonds, so they don’t move around. Basically, the pure silicon is an insulator and little electricity that flows through it. This structure of electrons can be changed is called a doping process. The process of doping means adding impurities in a controlled manner to Silicon. The amount of dopant or impurity added to an intrinsic Semiconductor determines the conductivity level of the Semiconductors. Because of these properties, the Semiconductors is helpful in making electronic devices so that their conductivity can be modified easily as required through doping.

Opportunity for Investors

According to the current statistics, the semiconductor industry has grown and is expected to grow to a greater extent in future. However, this figure is just an average estimation, if the sales growth of each company is analyzed, there will be a more commendable growth being observed. All in all, the performance of the semiconductor industry has remained exceptionally well. The demand and supply for the stocks of this industry has proven or shown an upward trend, which is verified by the sector’s industrial growth.

When it comes to the electronic devices,  semiconductors are the groundwork because they are the heart of the computer and the core of every electronic devices. So, don’t overlook its importance!

Semiconductor Technology: The Backbone of Its Classifications

Modern day by day living of human beings rely on the use of semiconductor parts. You may disagree in most part, but you will eventually discover that semiconductor has done the right thing. To those who disagree, they do not know what it is all about. Typically, semiconductors have essential roles in the areas of modern electronics because they are present in all traditional and digital devices, such as the mobile phones, tablets, cameras, computer, and radio production. To understand more about semiconductor technology, you must first identify its classifications.

Sophisticated equipment and gadgets will become available because of the consistent inventions being done. Such inventions have become possible – Thanks to the continuous scientific advancements. Unless they possess electrical conductivity, semiconductors will not function. Between that of an insulator and conductors, the conductivity often takes place. Upon understanding this, you will automatically have the background that revolves around the world of semiconductor technology. This might sound fundamental, but it needs lots of principles behind it. In this regard, it pays to know the different types of semiconductor that are critical in the businesses.


Intrinsic Semiconductor

Known as the purest among semiconductor classifications, Intrinsic semiconductors are comprised of thermal materials, which are capable of reducing covalent bonds while freeing some electrons. Part of its work is for the supplementation of electric component conductivity. In most cases, where the covalent bonds lose their electrical and electrons abilities of the semiconductor gets affected.

Extrinsic Semiconductor

Just like the doors and the windows, where there are exit and entrance. If there is a known intrinsic category of semiconductor, there is also an extrinsic. Unlike the intrinsic version, extrinsic semiconductors depend heavily doped or particles, known as a doped semiconductor. The additional particles being placed play a huge role in changing the conductivity qualities of each electrical component. One example of extrinsic semiconductors is the device that makes use of the usual semiconductor part, which is called a silicon. Test Contactor Through a process known as covalent bonding, each atom of silicon allots 4 categories of valence electrons. If silicon will be substituted by 5 valence electrons of phosphorous, 4 of the covalence electrons will be placed together while the remaining 1 will be free.

Extrinsic Semiconductors – N-Type and the P- Type

Extrinsic classifications come in 2 sub-classes. These types are regarded as the P-type and N-type semiconductors. As for the P-type semiconductor, it works the opposite functions with that of the N-type. This clearly shows that it adapt a semiconductor technology where the holes are the majority carriers, while the electrons function as minority carriers. As for the N-type in extrinsic semiconductor, holes and electrons are present. The P-type semiconductor as majority carriers, while the N-type plays as minority carriers. This shows that the concentrations of electrons are higher than that of the holes.

A semiconductor is a small, yet the most important element in the world of technology. Before understanding how semiconductors works, it pays to take a glimpse of understanding the classifications.
