    摘要: A transistor having an epitaxial channel and a method for fabricating a semiconductor device having an epitaxial channel, the method including forming a hardmask on a substrate and forming an opening in the hardmask. The opening is geometrically characterized by a long dimension and a short dimension, and the opening is arranged in a predetermined manner relative to the channel region of a transistor. An epitaxial material is formed in the opening that induces strain in substrate regions proximate to the epitaxial material. The epitaxial material is confined to the opening, such that an epitaxial channel is formed. A transistor is fabricated in proximity to the epitaxial channel, such that the strain induced in the substrate provides enhanced transistor performance. By confining the epitaxial material to a predefined channel in the substrate, plastic strain relaxation of the epitaxial material is minimized and a maximum amount of strain is induced in the substrate.

    摘要: A method for fabricating a semiconductor structure having heterogeneous crystalline orientations by forming a region including a semiconductor material having a specified crystalline orientation using an epitaxial buffer overlying a semiconductor substrate. The buffer provides a transfer body such that the semiconductor material has a crystalline orientation that differs from the crystalline orientation of a semiconductor region underlying the buffer. The method also includes fabricating a semiconductor structure having a p-type device region and an n-type device region, where a supporting semiconductor substrate is either n-type or p-type and where the semiconductor material is separated from the substrate by a buffer and has a crystalline orientation that differs from the crystalline orientation of the substrate.

    摘要: A method for fabricating a nitrogen-containing dielectric layer and semiconductor device including the dielectric layer in which a silicon oxide layer is formed on a substrate, such that an interface region resides adjacent to substrate and a surface region resides opposite the interface region. Nitrogen is introduced into the silicon oxide layer by applying a nitrogen plasma. After applying nitrogen plasma, the silicon oxide layer is annealed. The processes of introducing nitrogen into the silicon oxide layer and annealing the silicon oxide layer are repeated to create a bi-modal nitrogen concentration profile in the silicon oxide layer. In the silicon oxide layer, the peak nitrogen concentrations are situated away from the interface region and at least one of the peak nitrogen concentrations is situated in proximity to the surface region. A method for fabricating a semiconductor device is incorporating the nitrogen-containing silicon oxide layers also disclosed.
