Wide Bandgap Materials Doping
Our wide bandgap semiconductor doping services support advanced materials including SiC, GaN, and diamond for high-power, high-temperature, and next-generation electronic devices. We provide precise control of dopant species, dose, and depth profiles to meet demanding device requirements. Compared to conventional silicon processing, wide bandgap materials require specialized implantation, activation, and defect recovery strategies. Our processes are engineered to address challenges such as lattice damage, activation efficiency, and surface stability, ensuring consistent electrical performance. We support both N-type and P-type doping approaches for research, prototyping, and advanced device development. Our workflows are optimized for reliability and repeatability across high-voltage, high-frequency, and next-generation semiconductor applications.

Process focus areas
How wide-bandgap doping projects are approached
Material-specific dopant and implant planning
Wide-bandgap materials respond very differently from silicon, so implantation conditions, species choice, and damage considerations must be selected accordingly.
Electrical target review
The required outcome may involve channel engineering, contact region formation, carrier compensation, or target sheet resistance, all of which affect the doping route.
Activation and damage recovery integration
Wide-bandgap doping is inseparable from the activation strategy. High-temperature annealing, surface protection, and lattice recovery are essential parts of the full process path.
Device-structure compatibility
Implant windows, epitaxial layers, surface condition, and later metallization or passivation steps must all be considered to avoid integration failures.
Technical considerations
Key parameters for wide-bandgap doping
| Parameter | Typical consideration | Engineering note |
|---|---|---|
| Substrate platform | SiC, GaN, diamond, and related advanced materials | Each platform has distinct activation and damage behavior |
| Dopant type | N-type or P-type depending on device objective | Dopant choice affects thermal and electrical pathway |
| Implant profile | Single or multi-energy implantation | Used to tune depth and concentration distribution |
| Activation difficulty | Often more demanding than silicon | High-temperature recovery is commonly required |
| Surface protection | Capping or protective process options may be needed | Important during high-temperature annealing |
| Epitaxial compatibility | Implantation into or through epi structures may require careful review | Layer integrity must be preserved |
| Device relevance | Power switching, high-voltage, high-temperature, and harsh-environment devices | Doping must be tied to real device architecture |
Typical platforms and objectives
Typical applications
SiC power electronics
Doping strategies for high-voltage and high-temperature SiC device structures.
GaN device development

Engineering considerations
Wide-bandgap doping is not just a matter of implanting a dopant species. The material system, damage tolerance, activation difficulty, surface protection, and full thermal cycle must all be evaluated together. Strong results come from treating implantation, activation, and device integration as one connected process path.
