    摘要: A semiconductor structure and method of manufacturing is provided. The method of manufacturing includes forming shallow trench isolation (STI) in a substrate and providing a first material and a second material on the substrate. The first material and the second material are mixed into the substrate by a thermal anneal process to form a first island and second island at an nFET region and a pFET region, respectively. A layer of different material is formed on the first island and the second island. The STI relaxes and facilitates the relaxation of the first island and the second island. The first material may be deposited or grown Ge material and the second material may deposited or grown Si:C or C. A strained Si layer is formed on at least one of the first island and the second island.

    摘要: The present invention relates to an FET device having a conductive gate electrode with angled sidewalls. Specifically, the sidewalls of the FET device are offset from the vertical direction by an offset angle that is greater than about 0° and not more than about 45°. In such a manner, such conductive gate electrode has a top surface area that is smaller than its base surface area. Preferably, the FET device further comprises source/drain metal contacts that are also characterized by angled sidewalls, except that the offset angle of the source/drain metal contacts are arranged so that the top surface area of each metal contact is larger than its base surface area. The FET device of the present invention has significantly reduced gate to drain metal contact overlap capacitance, e.g., less than about 0.07 femtoFarads per micron of channel width, in comparison with conventional FET devices having straight-wall gate electrodes and metal contacts.

    摘要: A semiconductor structure and method of manufacturing is provided. The method of manufacturing includes forming shallow trench isolation (STI) in a substrate and providing a first material and a second material on the substrate. The first material and the second material form a first island and second island at an pFET region and a nFET region, respectively. A tensile hard mask is formed on the first and the second island layer prior to forming finFETs. An Si epitaxial layer is grown on the sidewalls of the finFETs with the hard mask, now a capping layer which is under tension, preventing lateral buckling of the nFET fin.

    摘要: A semiconductor device and method of manufacturing a semiconductor device. The semiconductor device includes channels for a pFET and an nFET. An SiGe layer is grown in the channel of the nFET channel and a Si:C layer is grown in the pFET channel. The SiGe and Si:C layer match a lattice network of the underlying Si layer to create a stress component in an overlying grown epitaxial layer. In one implementation, this causes a compressive component in the pFET channel and a tensile component in the nFET channel. In a further implementation, the SiGe layer is grown in both the nFET and pFET channels. In this implementation, the stress level in the pFET channel should be greater than approximately 3 GPa.

    摘要: A method for forming a semiconductor substrate structure is provided. A compressively strained SiGe layer is formed on a silicon substrate. Atoms are ion-implanted onto the SiGe layer to cause end-of-range damage. Annealing is performed to relax the strained layer. During the annealing, interstitial dislocation loops are formed as uniformly tributed in the SiGe layer. The interstitial dislocation loops provide a basis for nucleation of misfit dislocations between the SiGe layer and the silicon substrate. Since the interstitial dislocation loops are distributed uniformly, the misfit locations are also distributed uniformly, thereby relaxing the SiGe layer. A tensilely strained silicon layer is formed on the relaxed SiGe layer.

    摘要: A novel transistor structure and method for fabricating the same. First, a substrate, a semiconductor region, a gate dielectric region, and a gate block are provided. The semiconductor region, the gate dielectric region, and the gate block are on the substrate. The gate dielectric region is sandwiched between the semiconductor region and the gate block. The semiconductor region is electrically insulated from the gate block by the gate dielectric region. The semiconductor region and the gate dielectric region share an interface surface which is essentially perpendicular to a top surface of the substrate. The semiconductor region and the gate dielectric region do not share any interface surface that is essentially parallel to a top surface of the substrate. Next, a gate region is formed from the gate block. Then, first and second source/drain regions are formed in the semiconductor region.
