    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.

    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 3D quantum dot optical path structure is provided, along with a method for selectively forming a 3D quantum dot optical path. The method comprises: forming a single crystal Si substrate with a surface; forming a Si feature in the substrate, such as a via, trench, or pillar; forming dots from a Ge or SiGe material overlying the Si feature; and, forming an optical path that includes the dots. In some aspects of the method, the Si feature has defect sites. For example, the Si feature may be formed with a miscut angle. As a result of the miscut angle, steps are formed in the Si feature plane. Then, the dots are formed in the Si feature steps. The miscut angle is in the range between 0.1 and 5 degrees, and the spacing between steps is in the range between 1 and 250 nanometers (nm).

    摘要: Methods of forming a SiGe layer overlying an insulator are provided. A layer of SiGe is deposited on a substrate and implanted with ion to form a defect region within the SiGe material below its surface. The SiGe layer is then patterned and transferred by contact bonding to an insulator on a second substrate. After contact bonding the structure is annealed to split the SiGe layer along the defect region. The splitting anneal will relax the SiGe layer. Additional annealing at higher temperatures may be used to further relax the SiGe layer. A layer of strained silicon may then be epitaxial deposited on the resulting structure of relaxed SiGe on insulator. Another method provides for epitaxially depositing a layer of silicon over the SiGe layer prior to patterning. The silicon layer would then be bonded to the insulator on the second substrate. The splitting anneal and additional anneals, if any, should then induce strain into the silicon layer. The silicon layer would then remain over the insulator after the SiGe layer is removed.

    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.
