    摘要: Manufacturing an III-V engineered substrate involves providing a base substrate comprising an upper layer made of a first III-V compound with a or a crystal orientation, forming an intermediate layer comprising at least a buffer layer of a second III-V compound, wherein the intermediate layer is overlying and in contact with the upper layer of the base substrate. Then a pseudomorphic passivation layer made of a group IV semiconductor material is grown so as to be overlying and in contact with the intermediate layer. This can enable an unpinned interface. The substrate surface can be smoother, implying fewer problems from surface stress. It can be used in electronic devices such as metal-oxide-semiconductor field effect transistors (MOSFETs), high electron mobility transistors (HEMTs), tunneling field effect transistors (TFETs), and optoelectronic devices.

    摘要: A method for manufacturing a dual work function semiconductor device is disclosed. In one aspect, the method relates to providing a substrate with a first and a second region. A gate dielectric is formed overlying the first and the second region. A metal gate layer is formed overlying the gate dielectric on the first and the second region. The metal gate layer has a first (as-deposited) work function that can be modified upon inducing strain thereon. The method further relates to selecting a first strain which induces a first pre-determined work function shift (ΔWF1) in the first (as-deposited) work function of the metal gate layer on the first region and selectively forming a first strained conductive layer overlying the metal gate layer on the first region, the first strained conductive layer exerting the selected first strain on the metal gate layer.
