Metal foils, wires, and seamless tubes with increased mechanical strength are provided. As opposed to wrought materials that are made of a single metal or alloy, these materials are made of two or more layers forming a laminate structure. Laminate structures are known to increase mechanical strength of sheet materials such as wood and paper products and are used in the area of thin films to increase film hardness, as well as toughness. Laminate metal foils have not been used or developed because the standard metal forming technologies, such as rolling and extrusion, for example, do not lend themselves to the production of laminate structures.

A lateral heterojunction bipolar transistor (HBT) is formed on a semiconductor-on-insulator substrate. The HBT includes a base including a doped silicon-germanium alloy base region, an emitter including doped silicon and laterally contacting the base, and a collector including doped silicon and laterally contacting the base. Because the collector current is channeled through the doped silicon-germanium base region, the HBT can accommodate a greater current density than a comparable bipolar transistor employing a silicon channel. The base may also include an upper silicon base region and / or a lower silicon base region. In this case, the collector current is concentrated in the doped silicon-germanium base region, thereby minimizing noise introduced to carrier scattering at the periphery of the base. Further, parasitic capacitance is minimized because the emitter-base junction area is the same as the collector-base junction area.
