Assignee: TAIWAN SEMICONDUCTOR MANUFACTURING COMPANY LTD.
Field: Semiconductors (Electrical engineering)
Classification: CPC H | IPC H

Claim 18:
19. An integrated chip, comprising:
a substrate comprising a first semiconductor material;
a second semiconductor material disposed on the substrate, wherein the first semiconductor material is a different semiconductor material than the second semiconductor material;
a passivation layer disposed on the second semiconductor material;
a first doped region having a first doping type, the first doped region extending through the passivation layer and into the second semiconductor material, wherein the first doped region has a top that is vertically above a top of the second semiconductor material and a bottom that is vertically above a bottom of the second semiconductor material; and
a second doped region having a second doping type, the second doped region extending through the passivation layer and into the second semiconductor material.
