    摘要: A method of fabricating a capacitor including an ultra-high vacuum chemical vapor deposition (UHVCVD) step to generate a top-side barrier film layer including silicon nitride at monolayer quantities, and a capacitor so formed, are disclosed. The UHVCVD step allows silicon nitride to be deposited with monolayer level control, and is more successful at placing the nitrogen near the top surface independent of the base film thickness. The resulting capacitor exhibits thermal stability and meets leakage targets after, for example, an approximately 1050° C. thermal treatment. In addition, the UHVCVD nitride step allows for an in situ thermal clean and simpler process control because the reaction is thermally driven.

    摘要: A semiconductor structure is provided. The structure includes an n-type field-effect-transistor (NFET) being formed directly on top of a strained silicon layer, and a p-type field-effect-transistor (PFET) being formed on top of the same stained silicon layer but via a layer of silicon-germanium (SiGe). The strained silicon layer may be formed on top of a layer of insulating material or a silicon-germanium layer with graded Ge content variation. Furthermore, the NFET and PFET are formed next to each other and are separated by a shallow trench isolation (STI) formed inside the strained silicon layer. Methods of forming the semiconductor structure are also provided.

    摘要: A method for fabricating a CMOS structure is disclosed. The method includes the blanket disposition of a high-k gate insulator layer in an NFET device and in a PFET device, and the implementation of a gate metal layer over the NFET device. This is followed by a blanket disposition of an Al layer over both the NFET device and the PFET device. The method further involves a blanket disposition of a shared gate metal layer over the Al layer. When the PFET device is exposed to a thermal annealing, the high-k dielectric oxidizes the Al layer, thereby turning the Al layer into a PFET interfacial control layer, while in the NFET device the Al becomes a region of the metal gate.

    摘要: A semiconductor device and a method of making the device are provided. The method can include forming a gate conductor overlying a major surface of a monocrystalline semiconductor region and forming first spacers on exposed walls of the gate conductor. Using the gate conductor and the first spacers as a mask, at least extension regions are implanted in the semiconductor region and dummy spacers are formed extending outward from the first spacers. Using the dummy spacers as a mask, the semiconductor region is etched to form recesses having at least substantially straight walls extending downward from the major surface to a bottom surface, such that a substantial angle is defined between the bottom surface and the walls. Subsequently, the process is continued by epitaxially growing regions of stressed monocrystalline semiconductor material within the recesses. Then the dummy spacers are removed and the transistor can be completed by forming source/drain regions of the transistor that are at least partially disposed in the stressed semiconductor material regions.

    摘要: CMOS circuit structures are disclosed with the PFET and NFET devices having high-k dielectric layers consisting of the same gate insulator material, and metal gate layers consisting of the same gate metal material. The PFET device has a “p” interface control layer which is capable of shifting the effective-workfunction of the gate in the p-direction. In a representative embodiment of the invention the “p” interface control layer is aluminum oxide. The NFET device may have an “n” interface control layer. The materials of the “p” and “n” interface control layers are differing materials. The “p” and “n” interface control layers are positioned to the opposite sides of their corresponding high-k dielectric layers. Methods for fabricating the CMOS circuit structures with the oppositely positioned “p” and “n” interface control layers are also disclosed.
