    Abstract: Semiconductor layers on active areas for transistors in a memory cell region (region A) and a peripheral circuit region (region B) are simultaneously epitaxially grown in the same thickness in which the adjacent semiconductor layers in region A do not come into contact with each other. Only semiconductor layer (10) in region B is also grown from the surface of a substrate which is exposed when only the surface of STI (2) in region B is drawn back, so that a facet (F) of the semiconductor layer 10 is formed outside the active area, followed by ion-implantation to form a high density diffusion layer (11) in region B. Accordingly, short circuit between semiconductor layers on source/drain electrodes of transistors in region A is prevented, and uniformity of the junction depth of the layer (11) of the source/drain electrodes including an ESD region in a transistor of region B is obtained, thereby restricting the short channel effect.

    Abstract: By applying an AC pulse to a gate of a transistor which easily deteriorates, a shift in threshold voltage of the transistor is suppressed. However, in a case where amorphous silicon is used for a semiconductor layer of a transistor, the occurrence of a shift in threshold voltage naturally becomes a problem for a transistor which constitutes a part of circuit that generates an AC pulse. A shift in threshold voltage of a transistor which easily deteriorates and a shift in threshold voltage of a turned-on transistor are suppressed by signal input to a gate electrode of the transistor which easily deteriorates through the turned-on transistor. In other words, a structure for applying an AC pulse to a gate electrode of a transistor which easily deteriorates through a transistor to a gate electrode of which a high potential (VDD) is applied, is included.

  • Patent number: 8008664
    Abstract: An electrical component, in the crystalline semiconductor body of which several CMOS transistors in high-voltage or low-voltage technology are formed. The individual CMOS transistors are separated from one another by insulation regions. On one insulation region, a thin-film transistor is formed, having a gate that is realized simultaneously with the gates of the CMOS transistors from the same polysilicon layer. The gate oxide of the thin-film transistor, just like a second polysilicon layer for source drain and body of the thin-film transistor, can be produced together with the structural elements already present in the CMOS process.

  • Patent number: 8008146
    Abstract: A method (that produces a structure) patterns at least two wires of semiconductor material such that a first wire of the wires has a larger perimeter than a second wire of the wires. The method performs an oxidation process simultaneously on the wires to form a first gate oxide on the first wire and a second gate oxide on the second wire. The first gate oxide is thicker than the second gate oxide. The method also forms gate conductors over the first gate oxide and the second gate oxide, forms sidewall spacers on the gate conductors, and dopes portions of the first wire and the second wire not covered by the sidewall spacers and the gate conductors to form source and drain regions within the first wire and the second wire.
