Diffusion, Thin Films & Implant

CMOS and Bipolar technologies fabrication on 4" wafers.

PiN diode processes with low leakage characteristics and Low Noise JFET processes are also fabricated.

  • Diffusion up to 1250C (using SiC furnace tubes) with expertise on maintaining high bulk silicon lifetime during processing.
  • P type (Boron) doping processes either by Boron Discs, BBR3 or Boron Implantation.
  • N type (Phosphorous ,Arsenic and Antimony) doping processes either by furnace (phos only) or implant
  • LPCVD polysilicon for gate electrodes, resistors (to 1000 ohms/sq), poly to poly capacitors,  trench fill, and sacrificial layers for MEMS. Low temperature option to ensure smooth surfaces.
  • LPCVD Nitride for LOCOS, capacitor dielectrics, MEMS membranes and Masking layers
  • PECVD (low temperature) Oxide, Oxynitride and Nitride for inter level dielectric (ILD), circuit passivation, stress controlled (tensile and compressive) for thin membrane MEMS applications, and as sacrificial layers for MEMS.
