Electrostatic chuck

Electrostatic chucks and ceramic heaters can be produced by sintering materials with metallic electrodes arranged in the ceramics.
We produce electrostatic chucks and ceramic heaters catering to user needs by utilizing several material technologies. We can also provide services for the development and experimental production of electrostatic chucks and ceramic heaters according to region of use such as plasma and electron beam environments.


(1) Electrostatic chuck with heater (ESC/Heater)

【Material: AIN (Aluminum nitride)】

  • We achieve a wide temperature region and sufficient absorption force by controlling AIN volume resistivity.
  • Excellent temperature uniformity facilitated by a highly flexible heater design.
  • No time deterioration of electrodes is expected due to integrally sintered AIN and electrodes.
  • Using our bonding technology, we can produce electrostatic chucks with hollow structures or ceramic shafts.

(2) Electrostatic chucks (ESC)

 【Material: Al2O3(Alumina) 】

  • ・Our sheet lamination technology brings excellent thermal uniformity on the ceramic surface.
  • ・Metal contamination can be reduced by using high-purity alumina.
  • ・The product has excellent durability in halogen gas plasma environment.

 【Material: Thermal sprayed Al2O3

  • Our original alumina spraying technology delivers finely formed insulation layers.
  • We can produce at lower prices than alumina plate type chucks.
  • Products have higher durability than inexpensive film type chucks.

(3) Ceramic heater

 【Material: AIN (Aluminum nitride)】

  • We achieve excellent temperature uniformity of ±0.3% by using AIN having high thermal conductivity
  • We own characteristics inspection facilities such as IR cameras and TC wafers.
