Diffusion Sources for silicon doping | Saint-Gobain Boron Nitride

Diffusion Sources for Silicon Doping

PDS® Products P-type (Boron Nitride) and N-type (Silicon Phosphate based) offer low cost, in-situ and non-toxic diffusion sources for silicon wafers. PDS® Products eliminate the trade-off between throughput and uniformity.

PDS Products for silicon doping | Saint-Gobain Boron Nitride

All grades of PDS® Products are available in diameters up to 200 mm.  Use of PDS® Products enable the users to change sources diameter with little or no change in the diffusion process.  Furthermore, Saint-Gobain Advanced Ceramics Boron Nitride offers unparalleled technical guidance based on over 40 years of experience in diffusion technology.

Features & BenefitsDiffusion Carrier | Saint-Gobain Boron Nitride

  • Extreme flexibility that allows applications for many device structures, thereby eliminating capital expense in device conversion.
  • Improved yields and uniformity across the wafer, across a run and from run-to-run.
  • Precision chemical principles for predictability and repeatability through the controlled introduction of diffusion tube atmosphere.
  • H2-injection modulates the partial vapor pressure of the B2O3-HBO2 system for P-type, creating excellent uniformity and controlling the damage simultaneously for a low temperature process.
  • Non-toxic sources and safe to use.
