Advantages of Alumina Wafer Carrier

· Alumina wafer polishing carrier is made of 99.6% or more high-purity ultra-fine alumina powder, which is fired in a high temperature environment after molding. It is resistant to high temperature, wear and corrosion, and has no pollution to the wafer during grinding.

· The surface accuracy of the alumina wafer polishing carrier is high, and the flatness of the 800mm diameter disk can be controlled within 1.5 microns, which is conducive to improving the polishing accuracy of the wafer.

Applications of Alumina Wafer Carrier

Alumina wafer polishing carrier can be used as a carrier part in thinning, grinding and chemical mechanical polishing (cmp) processes for semiconductor wafers such as silicon wafers, gallium arsenide wafers and silicon carbide wafers
