摘要： A multi-layered barrier metal thin film is deposited on a substrate by atomic layer chemical vapor deposition (ALCVD). The multi-layer film may comprise several different layers of a single chemical species, or several layers each of distinct or alternating chemical species. In a preferred embodiment, the multi-layer barrier thin film comprises a Tantalum Nitride layer on a substrate, with a Titanium Nitride layer deposited thereon. The thickness of the entire multi-layer film may be approximately fifty Angstroms. The film has superior film characteristics, such as anti-diffusion capability, low resistivity, high density, and step coverage, when compared to films deposited by conventional chemical vapor deposition (CVD). The multi-layered barrier metal thin film of the present invention has improved adhesion characteristics and is particularly suited for metallization of a Copper film thereon.

摘要： Transistors fabricated on SSOI (Strained Silicon On Insulator) substrate, which comprises a strained silicon layer disposed directly on an insulator layer, have enhanced device performance due to the strain-induced band modification of the strained silicon device channel and the limited silicon volume because of the insulator layer. The present invention discloses SSOI substrate fabrication processes comprising various novel approaches. One is the use of a thin relaxed SiGe layer as the strain-induced seed layer to facilitate integration and reduce processing cost. Another is the formation of split implant microcracks deep in the silicon substrate to reduce the number of threading dislocations reaching the strained silicon layer. And lastly is a two step annealing/thinning process for the strained silicon/SiGe multilayer film transfer without blister or flaking formation.

摘要： A method is provided for forming a liquid phase epitaxial (LPE) germanium (Ge)-on-insulator (GOI) thin-film with a smooth surface. The method provides a silicon (Si) wafer, forms a silicon nitride insulator layer overlying the Si wafer, and selectively etches the silicon nitride insulator layer, forming a Si seed access region. Then, the method conformally deposits Ge overlying the silicon nitride insulator layer and Si seed access region, forming a Ge layer with a first surface roughness, and smoothes the Ge layer using a chemical-mechanical polish (CMP) process. Typically, the method encapsulates the Ge layer and anneals the Ge layer to form a LPE Ge layer. A Ge layer is formed with a second surface roughness, less than the first surface roughness. In some aspects, the method forms an active device in the LPE Ge layer.
