Ultra-precision Semiconductor Wafer Grinder

HY-WT9530 is fitted with 2 air-bearing spindles and 3 vacuum chuck tables for hard brittle substrates up to 8-inch. Operators only need to load cassettes manually, while the machine completes full automatic cycles including rough/fine grinding, cleaning and recovery. Post-grinding TTV≤1.5μm with excellent flatness and surface roughness, suitable for backside thinning of various semiconductor wafers.
