1. Introduction
Silicon (Si) is a non-metallic element that is between metal and non-metal. With properties of both metal and non-metal, silicon can act as a semiconductor material, and it is the dominant material in semiconductor industry. As a semiconductor material, silicon has many advantages. So, what are the advantages of using silicon as semiconductor material?
2. Advantages
● Rich resource
Silicon is the second most abundant element on Earth, and it has a wide existance in rock, sand and soil, making it easy to obtain, so its cost is relatively low.
● Excellent chemical stability and thermal conductivity
Silicon has extremely high chemical stability at room temperature, and it is not easy to react chemically with other substances, this can protect semiconductor devices from erosion. Meanwhile, silicon has high melting point, and good thermal conductivity, which ensure silicon work stably at higher temperature.
● Suitable conductivity
The conductivity of silicon is between that of conductors and insulators, with a moderate band gap (about 1.12 electron volts). This property enables silicon to support the flow of charge and limit the leakage of current, and then the stability and operational reliability of the device are guaranteed.
● Mature processing technology
After years of development, processing technologies of silicon have become very mature. They includes: purification, doping and etching, etc. These mature technologies provide technical support for large-scale production of silicon-based devices.
● Good doping ability
The crystal structure of silicon makes it easy for other elements to be incorporated into it. By adding a small amount of other elements (such as boron and phosphorus) into silicon crystal, the conductive property of silicon can be changed. Doped silicon is called impurity semiconductor, which has significantly improved conductivity and it is suitable for manufacturing various high-performance semiconductor devices.
3. Summary
In a word, silicon has become the first choice of semiconductor materials due to its unique advantages. With continuous improvement of doping technology and processing technology, people can better utilize the advantages of silicon as a semiconductor material to manufacture high-performance semiconductor devices that meet various needs.
