Abstract
A semiconductor device includes a substrate; a collector including a buried layer within the substrate, a first well region over a first portion of the buried layer, and a first conductivity region at least partially within the first well region; a base including a second well region over a second portion of the buried layer and laterally adjacent to the first well region, and a second conductivity region at least partially within the second well region; an emitter including a third conductivity region at least partially within the second conductivity region; an isolation element between the first and the third conductivity regions; a conductive plate on the isolation element and electrically connected with the first conductivity region. The buried layer, the first well region, the first and the third conductivity regions have a first conductivity type; the second well region and the second conductivity region have a second conductivity type.
