wafer grinding equipment

HY-WT9230 is developed for ultra-hard brittle semiconductor materials up to 12 inches. Built with dual air-bearing spindles and a high-precision grinding Z-axis, it supports fully automatic mirror thinning with high efficiency and damage-free processing. Equipped with a porous vacuum chuck and ultra-fine feed control, the machine ensures superior flatness and thickness uniformity for semiconductor wafer thinning processes.

The HY-ST3005 handles 4–12 inch hard brittle semiconductor substrates for high-precision back thinning. Iteratively upgraded for superior accuracy and long-term stability, it features premium core assemblies (hydrostatic air-bearing grinding spindle, high-precision wafer spindle, high-rigidity large-diameter rotary table) and high automation for mass production of silicon and compound semiconductor wafers.

The HY-ST3002 handles 4–12 inch wafers for precision thinning and grinding of hard brittle semiconductors. Fully upgraded with mature processes, it features enhanced accuracy and stable long-run performance, with refined automatic thinning architecture and premium key parts: hydrostatic air-bearing grinding spindle, hydrostatic air-bearing wafer holding spindle, high-rigidity large-diameter rotary table.
