Claim Text:
1. A semiconductor structure comprising: at least one first lateral bipolar transistor located atop a first portion of an insulator layer and comprising: an intrinsic base semiconductor material portion of a first conductivity type and having a bottommost surface, an uppermost surface, and two vertical sidewalls oriented in a width-wise direction; a first horizontal semiconductor material portion of said first conductivity type positioned between said bottommost surface of said intrinsic base semiconductor material portion of said first conductivity type and an uppermost surface of said insulator layer; a second horizontal semiconductor material portion of said first conductivity type located directly on said uppermost surface of said intrinsic base semiconductor material portion of said first conductivity type; a first sidewall semiconductor material portion of said first conductivity type located at one of said vertical sidewalls of said intrinsic base semiconductor material portion of said first conductivity type that is oriented in said width-wise direction; and a second sidewall semiconductor material portion of said first conductivity type located at another of said vertical sidewalls of said intrinsic base semiconductor material portion of said first conductivity type that is oriented in said width-wise direction, wherein said first horizontal semiconductor material portion of said first conductivity type, said second horizontal semiconductor material portion of said first conductivity type, and said first and second sidewall semiconductor material portions of said first conductivity type each have a higher dopant concentration than said intrinsic base semiconductor material portion of said first conductivity type and shield any surface of said intrinsic base semiconductor material portion from direct contact with an insulator material, wherein said first conductivity type consisting entirely of an n-type dopant or entirely of a p-type dopant.
