  • Publication number: 20040016897
    Abstract: Provided are apparatus and methods for detecting phase defects. The invention relies generally on the distortion of light as it passes through defects in phase shift masks to detect these defects. Light traveling through a defect, such as a bump in an etched area will travel at a different angle than light traveling through air. In order to enhance the signals generated from the defects, the invention in several embodiments provides a multiple element detector having at least four elements, arranged in a radially symmetric configuration. Individual elements of the detector are selected to form a differential signal based on the configuration of pattern lines in the area proximate to the defect. The resulting differential signal is used to generate an image signal and to identify phase defects.

    Abstract: The present invention relates generally to fabricating two-terminal electric microswitches comprising thin semiconductor films and using these microswitches to construct column-row (x-y) addressable microswitch matrices. These microswitches are two terminal devices through which electric current and electric potential (or their derivatives or integrals) can be switched on and off by the magnitude or the polarity of the external bias. The microswitches are made from semiconducting thin films in a electrode/semiconductor/electrode, thin film configuration. Column-row addressable electric microswitch matrices can be made in large areas, with high pixel density. Such matrices can be integrated with a sensor layer with electronic properties which vary in response to external physical conditions (such as photon radiation, temperature, pressure, magnetic field and so on), thereby forming a variety of detector matrices.

    Abstract: In a top gate type TFT wherein a gate electrode is formed above an active layer, an interlayer insulating film formed so as to cover a TFT active layer, a gate insulating film, and a gate electrode have a structure configured by laminating a SiNx film and a SiO2 film, in that order from an active layer side. The thickness of the SiNx film is between 50 nm-200 nm, more preferably on the order of 100 nm. Employing such a thickness ensures that a sufficient amount of hydrogen for terminating dangling bonds can be supplied to the active layer made of a semiconductor such as polycrystalline Si provided as a lower layer. Further, a higher accuracy of contact holes or the like formed in the interlayer insulating film can be assured.

  • Publication number: 20040016927
    Abstract: A current path pattern of semiconductor material is formed on the insulating principal surface of a substrate. A gate pattern three-dimensionally crosses the current path pattern in first and second cross areas. A channel region of the current path pattern is defined in an area superposed upon by the gate pattern. A gate insulating film is disposed between the current path pattern and gate pattern. The current path pattern has a lightly doped drain structure on both sides of the channel region in the first cross area, and is not provided with the lightly doped drain structure in regions in contact with the channel region in the second cross area. TFTs are provided having a small off-current and being not necessary for high precision position alignment during manufacture processes even if a gate length is short.

These metal parts form a light path. The light path reflects incident light which is entered from outside, thereby preventing the incident light from leaking to other photoelectric conversion elements. Therefore, it is possible to obtain a charge coupled device in which the disadvantage of color dispersion and color blurring between pixels adjacent to each other is suppressed.
