Field: Semiconductors (Electrical engineering)
Classification: CPC H | IPC H

Claim 9:
10. A structure for a lateral bipolar junction transistor, the structure comprising:
a substrate including a well;
a first terminal including a first raised semiconductor layer;
a second terminal including a second raised semiconductor layer;
a base layer positioned in a lateral direction between the first raised semiconductor layer of the first terminal and the second raised semiconductor layer of the second terminal, the base layer having an overlapping arrangement with the well; and
a dielectric layer positioned in a vertical direction between the first terminal and the substrate, the second terminal and the substrate, and the base layer and the substrate,
wherein the dielectric layer includes a recess aligned with the well, the recess penetrates partially through the dielectric layer, and the base layer includes a portion inside the recess.
