  Porous ceramic chuck table  is a so important part in semiconductor equipment such as silicon wafer processing. Porous Ceramic Vacuum Chucks  are widely used as important components of equipment in silicon wafer, semiconductor compound wafer, piezoelectric ceramic, glass, LED, semiconductor package component substrate, optical component thinning, cutting and so on. The advantages include the following: Strong permeability: Uniform air permeability and water permeability to ensure the uniform stress and firm adsorption of the silicon wafer, so that it does not slip during the grinding process. Compact and uniform structure: Due to the dense and uniform  microporous ceramic , the chuck table is not easy to adsorb silicon powder abrasives and is easy to clean. High strength: No deformation during grinding, to ensure that the silicon wafer is uniformly stressed at all points during grinding, and is not easy to edge breakage and debris. Long service life: The surface sh...

The range of Innovcera porous ceramic filters is made from aluminum oxide and silicon carbide. The strong, uniform porous ceramic has 40-50% open porosity with a tortuous pore structure and is available in pore sizes ranging from 1 to 100 microns. Maximum Temperature Up to 1000C for porous ceramic, limited only by sealants, gaskets and/or hardware materials. Corrosion Resistance Porous ceramics are resistant to most acids, except for Hydrofluoric Acid and Phosphoric Acid. In alkaline solutions, porous ceramics are resistant up to pH9. It is also resistant to organic solvents. The sealants, gaskets and/or hardware materials used, may be the limiting factor in certain fluids. Cleanability Porous ceramic is cleanable by a variety of methods, depending on the type of contaminant to be removed. Methods include spraying, brushing, backwashing, oven firing, dilute acid cleaning, solvent cleaning, steam cleaning and ultrasonic cleaning. Porous ceramics are used for: Ceramic Vacuum Chucks Cera...

Vacuum chucks are used in the thinning, dicing, cleaning, handling, and other processes of semiconductor electronic chips, like wafers. Why choose microporous ceramic vacuum chucks? 1. During the polishing and cleaning process of wafers, polishing liquid and water mist enter the working table, causing corrosion. And the microporous ceramic vacuum chucks resist corrosion. 2. The microporous ceramic vacuum chuck has no environmental pollution such as light, heat, and electromagnetic, unlike the rubber or other materials vacuum chuck. And the rubber or other materials vacuum chuck will be in direct contact with the surface of the item, so it is very easy to wear. Therefore, the porous ceramic has high temperature resistance and chemical corrosion resistance, light structure, and electrical insulation. So it is the best choice for vacuum chuck. 3. With its special porous structure, the microporous ceramic has very small holes and can be machined to very precise flatness. Combined with...
