Do you understand semiconductor equipment

Release date:2022-06-24

Semiconductor devices are electrical devices manufactured using semiconductor elements. A semiconductor refers to a material whose electrical conductivity is between that of a conductor and an insulator at room temperature. Semiconductors are widely used in radios, televisions, and temperature measurement. For example, a diode is a device made of semiconductors. A semiconductor is a material whose conductivity can be controlled, ranging from insulators to conductors. Semiconductor equipment includes laser marking machine, laser inkjet printer, packaging machine, pure water machine, etc.

Classification of semiconductor materials Semiconductor materials can be roughly divided into the following categories according to their chemical composition and internal structure:

1. Compound semiconductors are semiconductor materials composed of two or more elements.

2. Amorphous semiconductor material Glass used as semiconductor is a kind of amorphous amorphous semiconductor material, which is divided into oxide glass and non-oxide glass.

3. Elemental semiconductors are germanium, silicon, selenium, boron, tellurium, antimony, etc.

4. Organic Inductor Materials There are dozens of known organic semiconductor materials, including naphthalene, anthracene, polyacrylonitrile, phthalocyanine and some aromatic compounds, etc., which have not yet been used.
