Porous SiC ceramics are ceramic material that are fired at high temperatures and have a large number of interconnected or closed pores inside. It is also known as a microporous vacuum suction cup, with pore sizes ranging from 2 to 100um.


Porous SiC ceramics have been widely used in metallurgy, chemical industry, environmental protection, biology, semiconductor and other fields. Porous SiC ceramics can be prepared by foaming method, sol gel method, tape casting method, solid sintering method and impregnation pyrolysis method.

VeTek Semiconductor's porous SiC ceramics play the role of clamping and carrying wafers in semiconductor production. They are dense and uniform, high in strength, good in air permeability, and uniform in adsorption.


They effectively address many difficult problems such as wafer indentation and chip electrostatic breakdown, and help achieve the processing of extremely high-quality wafers.

Working principle of porous SiC ceramics: The silicon wafer is fixed by the vacuum adsorption principle. During processing, the small holes on the porous SiC ceramics are used to extract the air between the silicon wafer and the ceramic surface, so that the silicon wafer and the ceramic surface are at low pressure, thereby fixing the silicon wafer.


After processing, plasma water flows out of the holes to prevent the silicon wafer from adhering to the ceramic surface, and at the same time, the silicon wafer and the ceramic surface are cleaned.

There are several high requirements for porous SiC ceramics:


1. Strong vacuum adsorption

2. Flatness is very important, otherwise there will be problems during operation

3. No deformation and no metal impurities


Therefore, the Air absorption value of VeTek Semiconductor's porous SiC ceramics reaches -45KPA. At the same time, they are tempered at 1200℃ for 1.5 hours before leaving the factory to remove impurities and are packaged in vacuum bags.


Porous SiC ceramics are widely used in wafer processing technology, transfer and other links. They have made great achievements in bonding, dicing, mounting, polishing and other links.
