    摘要: A double gate metal-oxide semiconductor field-effect transistor (MOSFET) includes a fin, a first gate and a second gate. The first gate is formed on top of the fin. The second gate surrounds the fin and the first gate. In another implementation, a triple gate MOSFET includes a fin, a first gate, a second gate, and a third gate. The first gate is formed on top of the fin. The second gate is formed adjacent the fin. The third gate is formed adjacent the fin and opposite the second gate.

    摘要: An exemplary embodiment relates to a method for forming a metal oxide semiconductor field effect transistor (MOSFET). The method includes providing a substrate having a gate formed above the substrate and performing at least one of the following depositing steps: depositing a spacer layer and forming a spacer around a gate and gate insulator located above a layer of silicon above the substrate; depositing an etch stop layer above the spacer, the gate, and the layer of silicon; and depositing a dielectric layer above the etch stop layer. At least one of the depositing a spacer layer, depositing an etch stop layer, and depositing a dielectric layer comprises high compression deposition which increases in tensile strain in the layer of silicon.

    摘要: A method for forming fin structures for a semiconductor device that includes a substrate and a dielectric layer formed on the substrate is provided. The method includes etching the dielectric layer to form a first structure, depositing an amorphous silicon layer over the first structure, and etching the amorphous silicon layer to form second and third fin structures adjacent first and second side surfaces of the first structure. The second and third fin structures may include amorphous silicon material. The method further includes depositing a metal layer on upper surfaces of the second and third fin structures, performing a metal-induced crystallization operation to convert the amorphous silicon material of the second and third fin structures to a crystalline silicon material, and removing the first structure.

    摘要: A FinFET device employs strained silicon to enhance carrier mobility. In one method, a FinFET body is patterned from a layer of silicon germanium (SiGe) that overlies a dielectric layer. An epitaxial layer of silicon is then formed on the silicon germanium FinFET body. A strain is induced in the epitaxial silicon as a result of the different dimensionalities of intrinsic silicon and of the silicon germanium crystal lattice that serves as the template on which the epitaxial silicon is grown. Strained silicon has an increased carrier mobility compared to relaxed silicon, and as a result the epitaxial strained silicon provides increased carrier mobility in the FinFET. A higher driving current can therefore be realized in a FinFET employing a strained silicon channel layer.
