Description

C&D Semiconductor 8838A 6" Wafer Alloy Annealer H2/N2 Watlow 988 115V

Floor-standing wafer alloy annealer for 6-inch (150mm) semiconductor processing. Used for ohmic contact formation and alloy annealing in semiconductor fabrication with hydrogen/nitrogen gas mixture capability.

Specifications & What's Included

  • Model: 8838A / 8838 VP; 6.5-inch annealing hot plate
  • Process gases: H2/N2 (10/90), compressed air, nitrogen with pump-out capability
  • Watlow Series 988 process controller
  • Dwyer 4-channel rotameter flow meter bank (LPM Air)
  • 24 VDC solenoid valve bank (Fluid Dynamics Inc.)
  • 115V AC, single phase, 15A, 60Hz
  • Mobile with caster mounting; stainless steel enclosure

Applications

Wafer alloy annealing equipment is used in semiconductor manufacturing for ohmic contact formation and metallurgical processing of silicon wafers. Operates with controlled gas atmospheres to achieve precise thermal profiles. Commonly found in semiconductor fabs and processing facilities for device fabrication workflows.

Condition: Used
This C&D Semiconductor Services 8838A 6-inch Wafer Alloy Annealer has been inspected and is in good condition. It was pulled from a working environment where it was actively in use and functional. The stainless steel cabinet shows surface scuffs and smudging consistent with normal fab environment use. The hot plate, dome lid assembly, Watlow Series 988 process controller, Dwyer rotameter flow meter bank, solenoid valve manifold, and internal wiring all appear intact and complete. Gas hazard labels are present and legible. The unit rides on locking casters and the lower access bay is open, showing plumbing and wiring in organized condition. Please view our photo set and contact us if you have any questions.
