Porous SiC Vacuum Chucks
Semicorex porous SiC vacuum chucks are the highly specialized ceramic fixtures meticulously manufactured from high-performing porous silicon carbide ceramics, which engineered specifically for the firm adsorption and precise positioning of semiconductor wafers. By choosing Semicorex porous SiC vacuum chucks, you will gain higher production efficiency and consistent product yield.
As the high-precision processing fixtures, Semicorex porous SiC vacuum chucks utilize the principle of vacuum adsorption to achieve nanometer-level precision, particle-free cleanliness, and stress-free clamping. They are the indispensable components applied extensively in high-end semiconductor manufacturing, and their performance directly affects product efficiency, yield, and overall cost.
Working principle of porous SiC vacuum chucks
The porous SiC ceramic plate in Semicorex porous SiC vacuum chucks features numerous micron-sized pores, which enable the vacuum adsorption function of the vacuum chuck. During operation, the back of the porous SiC vacuum chuck is connected to the vacuum pump. And then air between the vacuum chuck and the wafer is drawn out via micron-sized pores, creating a negative pressure area. It is this consistent and uniform negative pressure that allows the semiconductor wafers to be evenly clamped and precisely secured in place.
Advantages of Semicorex porous SiC vacuum chucks
1. Excellent durability for the high hardness and wear resistance of SiC ceramics.
2. Remarkable chemical stability and resistance to corrosion from most strong acids and alkalis.
3. Reliable electrical insulation properties and antistatic performance.
4. Exceptional high-temperature resistance and thermal shock resistance.
5. Consistent and secure clamping performance benefiting from the uniformly distributed microporous structure.
6.Special lightweight configuration for their low-density porous SiC materials.
7.Extreme surface flatness and parallelism, delivering nanometer-level positioning precision.
Applications of Semicorex porous SiC vacuum chucks
Featuring multiple advantages, Semicorex porous SiC vacuum chucks are extensively applied in the state-of-the-art semiconductor manufacturing processes, such as wafer thinning, wafer dicing, wafer grinding, and wafer testing. Their superior clamping performance enables semiconductor wafers to be fixed firmly and securely to porous SiC vacuum chucks, significantly preventing surface scratches and dents of wafers resulting from inconsistent and unstable negative pressure.
