摘要： A floating body germanium (Ge) phototransistor and associated fabrication process are presented. The method includes: providing a silicon (Si) substrate; selectively forming an insulator layer overlying the Si substrate; forming an epitaxial Ge layer overlying the insulator layer using a liquid phase epitaxy (LPE) process; forming a channel region in the Ge layer; forming a gate dielectric, gate electrode, and gate spacers overlying the channel region; and, forming source/drain regions in the Ge layer. The LPE process involves encapsulating the Ge with materials having a melting temperature greater than a first temperature, and melting the Ge using a temperature lower than the first temperature. The LPE process includes: forming a dielectric layer overlying deposited Ge; melting the Ge; and, in response to cooling the Ge, laterally propagating an epitaxial growth front into the Ge from an underlying Si substrate surface.

摘要： A method of fabricating local interconnect on a silicon-germanium 3D CMOS includes fabricating an active silicon CMOS device on a silicon substrate. An insulator layer is deposited on the silicon substrate and a seed window is opened through the insulator layer to the silicon substrate and to a silicon CMOS device gate. A germanium thin film is deposited on the insulator layer and into windows, forming a contact between the germanium thin film and the silicon device. The germanium thin film is encapsulated in a dielectric material. The wafer is heated at a temperature sufficient to flow the germanium, while maintaining the other layers in a solid condition. The wafer is cooled to solidify the germanium as single crystal germanium and as polycrystalline germanium, which provides local interconnects. Germanium CMOS devices may be fabricated on the single crystal germanium thin film.
