Diffusion Sources for Silicon Doping
PDS® P-type boron nitride-based wafers offer low cost, non-toxic in-situ diffusion sources for doping silicon wafers. PDS® products eliminated the trade-off between throughput and uniformity.
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 Boron Nitride offers unparalleled technical guidance based on over 40 years of experience in diffusion technology.
Features & BenefitsKey ApplicationsDevices
- 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.
