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 is provided for forming a matching thermal expansion interface between silicon (Si) and gallium nitride (GaN) films. The method provides a (111) Si substrate and forms a first aluminum (Al)-containing film in compression overlying the Si substrate. Nano-column holes are formed in the first Al-containing film, which exposes regions of the underlying Si substrate. A layer of GaN layer is selectively grown from the exposed regions, covering the first Al-containing film. The GaN is grown using a lateral nanoheteroepitaxy overgrowth (LNEO) process. The above-mentioned processes are reiterated, forming a second Al-containing film in compression, forming nano-column holes in the second Al-containing film, and selectively growing a second GaN layer. Film materials such as Al2O3, Si1-xGex, InP, GaP, GaAs, AlN, AlGaN, or GaN, may be initially grown at a low temperature. By increasing the growth temperatures, a compressed layer of epitaxial GaN can be formed on a Si substrate.

摘要： A floating body germanium (Ge) phototransistor with a photo absorption threshold bias region, and an associated fabrication process are presented. The method includes: providing a p-doped Silicon (Si) substrate; selectively forming an insulator layer overlying a first surface of the Si substrate; forming an epitaxial Ge layer overlying the insulator layer; forming a channel region in the Ge layer; forming a gate dielectric, gate electrode, and gate spacers; forming source/drain (S/D) regions in the Ge layer; and, forming a photo absorption threshold bias region in the Ge layer, adjacent the channel region. In one aspect, the second S/D region has a length, longer than the first S/D length. The photo absorption threshold bias region underlies the second S/D region. Alternately, the second S/D region is separated from the channel by an offset, and the photo absorption threshold bias region is the offset in the Ge layer, after a light p-doping.
