    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.

The method comprises: forming a Si substrate with a surface; forming a Si feature, normal with respect to the Si substrate surface, such as a via, trench, or pillar; depositing SiGe overlying the Si normal feature to a thickness in the range of 5 to 1000 nanometers (nm); and, forming a SiGe optical path normal structure having an optical path length in the range of 0.1 to 10 microns. Typically, the SiGe has a Ge concentration in the range from 5 to 100%. The Ge concentration may be graded to increase with respect to the deposition thickness. For example, the SiGe may have a 20% concentration of Ge at the Si substrate interface, a 30% concentration of Ge at a SiGe film top surface, and a thickness of 400 nm.
