    摘要: A novel MOS transistor having minimal junction capacitance in this method of fabrication. According to the present invention, a gate dielectric layer is formed on a first surface of the semiconductor substrate. A gate electrode is then formed on the gate dielectric layer. Next, a pair of recesses are formed in the semiconductor substrate on opposite sides of the gate electrode. A dielectric layer is then formed on the surface of each of the recesses. A Semiconductor material is then deposited into the recesses to form a pair of source/drain regions.

    摘要: A process is described for manufacturing an improved PMOS semiconductor transistor. Recesses are etched into a layer of epitaxial silicon. Source and drain films are deposited in the recesses. The source and drain films are made of an alloy of silicon and germanium. The alloy is epitaxially deposited on the layer of silicon. The alloy thus has a lattice having the same structure as the structure of the lattice of the layer of silicon. However, due to the inclusion of the germanium, the lattice of the alloy has a larger spacing than the spacing of the lattice of the layer of silicon. The larger spacing creates a stress in a channel of the transistor between the source and drain films. The stress increases IDSAT and IDLIN of the transistor. An NMOS transistor can be manufactured in a similar manner by including carbon instead of germanium, thereby creating a tensile stress.
