    Abstract: A semiconductor device has a cell region where transistor cells of a trench structure are arranged in a matrix form, in which a recessed trench is formed in a semiconductor layer, a gate oxide film is formed inside the recessed trench, and a gate electrode formed of polysilicon is disposed inside the recessed trench. To have contact with a gate wiring formed of a metal film, a gate pad disposed continuously to the gate electrode is placed inside a recessed part formed in the same depth as the recessed trench. Consequently, many transistor cells of the trench structure are formed in a matrix form. Even in a semiconductor device where the gate wiring formed of a metal film is contacted with the gate electrode, a semiconductor device of a structure allowing gate voltage to be increased sufficiently can be obtained.

  • Method and apparatus for solidification-controllable induction melting of alloy with cold copper crucible
    Patent number: 6798821
    Abstract: A method for solidification-controllable induction melting of alloy with cold copper crucible employs the vacuum induction furnace with cold crucible to melt metals, particularly active metals, to obtain alloy ingots having directionally solidified structure at the same time. By using the cold crucible also as a solidification mold in the melting of metal materials, controlling working parameters of the induction furnace, and changing the copper crucible design, it is possible to control the solidified structure of the melted alloy and obtain high quality ingots having impurity-free and directionally arranged or fine-crystalline structure. The problem of low metal melting efficiency in the conventional vacuum induction furnace with cold crucible due to loss of a large amount of heat carried away by cooling water for cooling the crucible can therefore be overcome.

  • Two-domain in-plane switching mode LCD
    Patent number: 6798484
    Abstract: An in-plane switching mode liquid crystal display (IPS-LCD). A plurality of lengthwise-extending common electrodes are formed in each pixel area, and each common electrode has a curved or zigzag profile. A plurality of lengthwise-extending pixel electrodes are formed in each pixel area, and each pixel electrode has a curved or zigzag profile. The pixel electrodes are disposed in the intervals between the common electrodes, and two adjacent pixel and common electrodes form a subpixel area. Liquid crystal molecules are positioned within each sub-pixel area. The two adjacent pixel electrode and common electrodes within each sub-pixel area are not parallel to each other, and thus a gradient in-plane electric field is generated therebetween.
