Claim 13:
14. A method of forming a structure for a lateral bipolar junction transistor, the method comprising:
forming a well in a substrate;
forming a first terminal that includes a first raised semiconductor layer;
forming a second terminal that includes a second raised semiconductor layer; and
forming 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,
wherein the base layer has an overlapping arrangement with the well, a dielectric layer is 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, a device layer is positioned on the dielectric layer, the device layer comprises silicon, the base layer comprises silicon-germanium, the first raised semiconductor layer is positioned on a first section of the device layer, the second raised semiconductor layer is positioned on a second section of the device layer, and the base layer is positioned in a first opening penetrating fully through the device layer between the first section of the device layer and the second section of the device layer.
