Assignee: PRISMATIC SENSORS AB
Field: Semiconductors (Electrical engineering)
Classification: CPC H  G | IPC G  H

Claim 15:
16. A method for constructing an X-ray sensor, said method comprises the steps of:
providing a plurality of detector diodes on a surface region of a material substrate;
providing said material substrate with a junction termination surrounding said surface region; wherein said junction termination is constructed by:
providing a guard adjacent said surface region;
providing a field stop outside of said guard;
arranging at least two field limiting rings, FLRs between said guard and said field stop, where a first FLR is arranged at a distance Δ1 from the guard selected from the interval [4 μm; 12 μm], a second FLR is arranged at a distance Δ2 from the first FLR selected from the interval [6.5 μm; 15 μm], wherein the distance Δ2 is larger than the distance Δ1.
