    Abstract: Structures for a field-effect transistor and methods of forming a structure for a field-effect transistor. First and second gate structures extend over the semiconductor body. A source/drain region is positioned laterally between the first gate structure and the second gate structure. The source/drain region includes a semiconductor layer having a first section, a second section, and a third section. A first portion of the semiconductor body is positioned between the first section of the semiconductor layer and the second section of the semiconductor layer. A second portion of the semiconductor body is positioned between the second section of the semiconductor layer and the third section of the semiconductor layer.

    Abstract: Structures for a heterojunction bipolar transistor and methods of forming a structure for a heterojunction bipolar transistor. A collector layer includes an inclined side surface, and a dielectric layer is positioned in a lateral direction adjacent to the inclined side surface of the collector layer. An intrinsic base is disposed over the collector layer, and an emitter is disposed over the intrinsic base. An airgap is positioned between the dielectric layer and the inclined side surface of the collector layer in the lateral direction, and an extrinsic base is positioned in the lateral direction adjacent to the intrinsic base. The extrinsic base is positioned over the airgap.
