Top Silicon Wafer Manufacturing Companies in the World

A semiconductor company can either manufacture silicon wafers or design chips manufactured by some other company.

What is a semiconductor?

A Semiconductor can be defined as a material that has the characteristics and ability to conduct a small amount of electrical current in a controlled manner. Semiconductors have much lower resistance to the flow of electrical current in one direction than in another. Diodes, transistors, and many photovoltaic cells contain semiconductive material. The electrical conductivity of a semiconductor can be controlled over a wide range, either permanently or dynamically.

Material Used to Manufacture Semiconductors

There are several materials that are used to make a semiconductor. The basic requirement of a semiconductor material is that it should not be a very good conductor of electricity, nor should it be a very bad conductor of electricity. Its properties can be changed by adding or removing atoms. Silicon is the most widely used semiconductor material. Few other materials used in making semiconductor are germanium, gallium arsenide, and silicon carbide.

What is a Silicon Wafer?

A wafer is a thin piece of semiconductor material, normally silicon crystal. These wafers are used to fabricate integrated circuits (ICs) and other microdevices. Silicon wafers are available in a variety of sizes ranging from 25.4 mm (1 inch) to 300 mm (11.8 inches).
