Claim 0:
1. 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 the base layer comprising silicon-germanium;
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; and
a device layer comprising silicon, the device layer positioned on the dielectric layer, the device layer including a first section, a second section, and a first opening disposed in the lateral direction between the first section and the second section, and the first opening penetrating fully through the device layer,
wherein the first raised semiconductor layer is positioned on the first section of the device layer, the second raised semiconductor layer is positioned on the second section of the device layer, and the base layer is positioned inside the first opening in the device layer.
