Core Advantages Of Porous Ceramic Vacuum Chuck
Extreme temperature resistance
Long-term working temp 1600°C; thermal shock ΔT ≥ 500°C.
Precision micro-porous adsorption
Porosity 30–70%, pore size 1–50 μm; vacuum adsorption ≥ 0.08 MPa for ultra-thin wafers.
Corrosion & wear resistance
Resists pH 1–14 & plasma erosion; HV10 2200–2800; service life 3× of graphite chucks.
Ultra-high flatness
≤ 0.005 mm after precision grinding.
Key Applications Of Porous Ceramic Vacuum Chuck
1.Semiconductor & Electronics
- Wafer bonding / temporary bonding: flatness ≤0.005 mm for 12-inch wafer thinning.
- Lithography thermal management: temperature fluctuation ≤±0.1°C.
2.Photovoltaic & New Energy
- PERC/TOPCon solar cell sintering furnace: 1600°C, breakage rate ≤0.01%.
- SiC epitaxial tray: metal impurity ≤1 ppm for MOCVD/MBE.
3.Laser & Precision Machining
- High-power laser cutting chuck: resists laser ablation ≥1 kW/cm².
- 3D printing substrate: porous ventilation reduces powder adhesion.
4. High-Temperature Industrial Equipment
- Sintering furnace setter: creep resistance, load ≥50 kg/m² at 1600°C.
- Vacuum brazing fixture: resists Ag-Cu-Ti solder; reusable ≥1000 cycles.
