Vacuum pump in electronic semiconductor industry application

The electronics and semiconductor industries are revolutionizing our lives, enabling us to enjoy the pleasure and comfort of science and technology. Vacuum equipment plays an extremely important role in the production process of electronic products and semiconductor equipment. In view of the special production requirements, it is necessary to select suitable vacuum equipment. Vacuum products are mainly used in the following fields of electronics and semiconductors:
Electron accelerator, photoelectric device, electronic material, X-ray tube, crystal oscillator, relay, laser, ion implantation equipment, ion etcher, chemical vapor deposition equipment, physical vapor deposition equipment, molecular beam epitaxy equipment, integrated circuit packaging, other semiconductor application equipment.
After tracing back to the industry, dry screw vacuum pump can be divided into three categories: production vacuum (medium and high vacuum); cleaning vacuum (rough vacuum); process vacuum (rough vacuum). Different types of fields require different vacuum pumps.

Vacuum for production mainly reduces the air in the working space and keeps the working space clean through high vacuum. The main types of vacuum pumps used include dry pump (dry screw vacuum pump, claw pump) and molecular pump and its units. The vacuum equipment used in production is larger in quantity and smaller in power per unit.
Cleaning vacuum mainly uses negative pressure and atmospheric pressure difference for liquid or particle removal or transportation. This kind of application mainly uses water ring pump and multi-stage centrifugal fan. Because of low vacuum, multi-stage centrifugal fan is more used. Vacuum source is a part of its system.
Process vacuum mainly uses negative pressure adsorption to carry or clamp workpieces. Dry pumps such as screw pumps, claw pumps, water ring pumps, rotary vane pumps and micro-oil screw pumps are common vacuum equipment in process vacuum.
