    摘要: A semiconductor device (10) is formed by positioning a gate (22) overlying a semiconductor layer (16) of preferably silicon. A semiconductor material (26) of, for example only, SiGe or Ge, is formed adjacent the gate over the semiconductor layer and over source/drain regions. A thermal process diffuses the stressor material into the semiconductor layer. Lateral diffusion occurs to cause the formation of a strained channel (17) in which a stressor material layer (30) is immediately adjacent the strained channel. Extension implants create source and drain implants from a first portion of the stressor material layer. A second portion of the stressor material layer remains in the channel between the strained channel and the source and drain implants. A heterojunction is therefore formed in the strained channel. In another form, oxidation of the stressor material occurs rather than extension implants to form the strained channel.

    摘要: A semiconductor fabrication process includes forming an etch stop layer (ESL) overlying a buried oxide (BOX) layer and an active semiconductor layer overlying the ESL. A gate electrode is formed overlying the active semiconductor layer. Source/drain regions of the active semiconductor layer are etched to expose the ESL. Source/drain stressors are formed on the ESL where the source/drain stressors strain the transistor channel. Forming the ESL may include epitaxially growing a silicon germanium ESL having a thickness of approximately 30 nm or less. Preferably a ratio of the active semiconductor layer etch rate to the ESL etch rate exceeds 10:1. A wet etch using a solution of NH4OH:H2O heated to a temperature of approximately 75° C. may be used to etch the source/drain regions. The ESL may be silicon germanium having a first percentage of germanium. The source/drain stressors may be silicon germanium having a second percentage of germanium for P-type transistors, and they may be silicon carbon for N-type transistors.

The power-electronic unit measures an electrical parameter of the output of the generator set. Based on the measured electrical parameter and a predefined criterion, the power-electronic unit determines additional energy required by the electrical load. Thereafter, the power-electronic unit supplies the additional energy to the electrical load. The additional energy is drawn from the energy storage unit.

    摘要: A semiconductor device structure is made on a semiconductor substrate having a semiconductor layer having isolation regions. A first gate structure is formed over a first region of the semiconductor layer, and a second gate structure is over a second region of the semiconductor layer. A first insulating layer is formed over the first and second regions. The first insulating layer can function as a mask during an etch of the semiconductor layer and can be removed selective to the isolation regions and the sidewall spacers. The first insulating layer is removed from over the first region to leave a remaining portion of the first insulating layer over the second region. The semiconductor layer is recessed in the first region adjacent to the first gate to form recesses. A semiconductor material is epitaxially grown in the recesses. The remaining portion of the first insulating layer is removed.
