Patent ID: 11887981
Assignee: SEMICONDUCTOR COMPONENTS INDUSTRIES, LLC
Field: Semiconductors (Electrical engineering)
Classification: CPC H | IPC H

Claim 0:
1. An apparatus comprising:
a semiconductor layer of a first conductivity type;
a lateral bipolar device disposed in the semiconductor layer; and
an isolation trench disposed in the semiconductor layer in a base region of the lateral bipolar device, the isolation trench being disposed between an emitter implant of the lateral bipolar device and a collector implant of the lateral bipolar device, the emitter implant and the collector implant being of a second conductivity type, opposite the first conductivity type, the isolation trench having a depth in the semiconductor layer that is greater than a depth of the emitter implant in the semiconductor layer, and greater than a depth of the collector implant in the semiconductor layer, wherein the isolation trench is not disposed between the emitter implant and a base implant disposed in the semiconductor layer.
