Understanding the Silicon Wafer

Are you looking to buy silicon wafers? Here are some important points that you need to consider while buying a wafer product. You must consider the quality of material being used to fabricate, diameter of the wafer and resistivity.  

Type of Silicon Wafers:

The wafer type depends on the conductivity requirements. Wafers carry a particular charge and commonly referred to as either N-Type and P-Type.

• N-type Silicon Wafers: Silicon wafers that have more electrons in their current carriers are negative charges and referred to as N-Type.
• P-type Silicon Wafers: When Silicon wafers are missing electrons from their current carriers, they have a positive charge, so they are P-Type.

Charges on the silicon wafers is given by the addition of dopants. P-type silicon wafers are produced by doping with boron. It produces positively charged silicon wafers. Doping with  Phosphorous, Antimony, and Arsenic produces N-Type wafer  carry  a negative charge on the surface.

Dopant and its effect on Resistivity:

The Dopant is an impurity that is added to the silicon during the production process. A dopant  functions by altering the chemical properties of the silicon wafer. Therefore, resistivity of a silicon wafer greatly depends upon the Dopant and the amount in which it is doped.

Property of Resistivity:  

Resistivity refers to the current flow and electron movement in the silicon. Depending on the purpose of the wafer, the resistivity needs to be altered through doping. The resistivity is decreased by adding more dopants to the silicon. Materials that have been heavily doped used to have lower resistivity.

Understanding Wafer Size:

Silicon Wafer Pricing is an essential element in the realization of integrated circuits production and manufacturing. Increasing the wafer size requires a lot of investment. Silicon wafer manufacturing technologies were re-engineered to achieve the necessary increase in the wafer size. In the last few years, wafer size has increased from 1 inch wafers to300mm i.e. 11.8 times larger. Many manufactures are working on a clear plan to increase the wafer size to1.5 times larger than 300mm. A larger wafer diameter enables producing more semiconductor devices from a single waferto enhance the productivity and efficiency. 

Important Points to Consider Before Buying Silicon Wafers

The Wafer is a thin semiconductor material made up of silicon crystal used in fabrications of the integrated circuits. Similarly, you will be able to find solar wafers that are mostly used for the solar panels that are installed on top of the roofs. Solar wafers have the ability to attract the light and heat from sunlight and produce electricity. This is the main reason, why a lot of people are installing the wafers in their offices and homes.

Using solar wafers you can produce your own electricity. Most of the people find it difficult to buy a good quality silicon wafer from their area. If you are one of them, researching on the Internet could be the best option. You can go through various websites from which you can choose the finest silicon wafer.

However, before buying wafers for your solar panels online, it is very important to perform a careful research. Also ensure that you are obtaining the right quality product. There are many websites that are providing wafers online, but not all of them can provide you a good quality product. Only buy from well established and reputable silicon wafer suppliers.

Therefore, before buying the wafers, it is very essential to perform a small background research of the silicon wafer supplier and make sure you are receiving high quality for the money you invest. You can also compare and choose the best wafer as there are many products of different companies available online. This is also one of the amazing benefits of buying wafers online.

Furthermore, you can compare the prices and choose the best according to your budget. In case, if you are not able to get the right wafer according to your requirement, taking the assistance of an expert could be the best option. As they will consider your needs, budget and help you in choosing the right silicon wafer.
