Why Power Chips Need Edge Termination
Electric field lines crowd naturally at the sharp curved perimeter edges of power dies, which would cause premature breakdown at 20–40% of the bulk rating.
Edge termination engineering uses lightly doped P-type rings (FLRs) and junction termination extensions to spread the electric field gradually to the die edge.
- Why Power Chips Need Edge Termination: Primary process parameter dictating vertical voltage blocking, specific on-resistance, and power device efficiency.
- Process Window Optimization: Maximizing lithography, plasma etch, oxidation, and deposition margins across 200mm/300mm power fabs.
- Defect Mitigation: Eliminating killer crystallographic dislocations, trench micro-scalloping, and gate dielectric pinholes.
- Vertical Conduction: Minimizing substrate and drift layer series resistance to minimize conduction power losses (I²R).
Field-Limiting Rings (FLRs) & JTE Implantation
Edge termination engineering uses lightly doped P-type rings (FLRs) and junction termination extensions to spread the electric field gradually to the die edge.
Channel-stop N+ rings at the outer die perimeter prevent depletion regions from reaching the saw street, preserving high-voltage isolation.
- Field-Limiting Rings (FLRs) & JTE Implantation: In-situ optical emission spectroscopy, real-time RF match monitoring, and automated high-throughput wafer transfer.
- Thermal Budget & Junction Profiling: Preserving abrupt source/body junctions and ensuring high-temperature stability during back-end processing.
- Field Crowding Prevention: Rounding trench corners and tailoring termination guard rings to achieve ideal 1D planar breakdown voltages.
- Yield Impact: Direct correlation between unit-step uniformity and functional high-voltage power die per wafer (DPW).
