Patent ID: 7989328

Claim:
A method of forming regions of a P-I-N diode comprising: providing a semiconductor body; providing first and second doped bodies adjacent and running along opposite sides of the semiconductor body, the first and second doped bodies containing a dopant of a first selected conductivity type; providing a third doped body overlying the semiconductor body, the third doped body containing a dopant of a second selected conductivity type opposite the first selected conductivity type; diffusing dopant of the first selected conductivity type from the first and second doped bodies into the semiconductor body to form a first region of the first selected conductivity type in the semiconductor body, the first region of the first selected conductivity type in the semiconductor body making up part of a P-I-N diode; diffusing dopant of the second selected conductivity type from the third doped body into the semiconductor body to form a region of the second selected conductivity type in the semiconductor body, the region of the second selected conductivity type in the semiconductor body making up part of a P-I-N diode; and diffusing dopant of the first selected conductivity type from the first and second doped bodies into the semiconductor body to form the first region and a second region of the first selected conductivity type in the semiconductor body, the second region making up part of a P-I-N diode.
