A ratio of a static beam-spot diameter Ws in the sub-scan direction on the surface of the photosensitive body defined by 1/e2 of the maximum value in the exposure distribution of the beam spot to an interval L between adjacent scan lines satisfies the following formula: 1.2<Ws/L<4.5.

Abstract: This invention is related to an active matrix liquid crystal display (AMLCD) or an X-ray imaging device having a high aperture ratio, and method of making same. The imager or display has an increased aperture ratio because electrodes are formed over dual insulating layers so as to overlap portions of the array address lines and/or TFTs.

An intermediate inorganic insulating layer is provided between the photo-imageable organic insulating layer and the overlapped TFTs in order to prevent the organic insulating layer from directly contacting semiconductor material in the TFTs thereby reducing potential voltage swings.

Abstract: A liquid crystal display device, and a fabricating method thereof, with improved bonding of an upper plate to a lower plate. The lower plate includes an organic protective film over an inorganic gate insulating layer that is on a substrate. Channels through the organic protective film expose either metal patterns or the gate insulating layer. A seal coated with a sealant is then placed over the organic protective film and channels. The sealant passes through the channels to the metal patterns or to the gate insulating layer.

During LCD fabrication, the metal patterns act as etch stops when etching the channels. Alternatively, an etch stop semiconductor layer is placed on the gate insulating film. The etch stops prevent the etching process from exposing the lower substrate.

Abstract: A method and apparatus for detection of a particular material, such as photo-resist material, on a sample surface. A narrow beam of light is projected onto the sample surface and the fluoresced and/or reflected light intensity at a particular wavelength band is measured by a light detector. The light intensity is converted to a numerical value and transmitted electronically to a logic circuit which determines the proper disposition of the sample. The logic circuit controls a sample-handling robotic device which sequentially transfers samples to and from a stage for testing and subsequent disposition. The method is particularly useful for detecting photo-resist material on the surface of a semiconductor wafer.

Abstract: In a double beam spectrophotometer, a sample beam is irradiated to a large-sized sample in a substantially vertical direction, and the beam upwardly transmitted through the large-sized sample is reflected by a reflecting mirror and sent to an integrating sphere including a detector. A reference beam irradiated parallel to the sample beam is deflected by reflecting mirrors such that the reference beam goes around the large-sized sample, and guided to the integrating sphere. Thus, a holder is not required to correspond to a size or shape of the sample, and measurement position can be freely changed by moving the sample. Also, in case of utilizing a conventional standard sample chamber, movable reflecting mirrors are inserted in the optical paths to transfer the beams to the standard sample chamber.

Abstract: A surface inspection device irradiates a laser beam onto the surface of a sample, scans the surface two-dimensionally, and detects the intensities of the s-polarized light component and p-polarized light component of the reflected laser beam. RR (reflectance ratio), which is the ratio of the reflective intensities of the s- and p-polarized light components, is calculated for each position of the surface of the sample, and the two-dimensional distribution of RR on the surface of the sample is detected. The distribution width of this measured RR is compared with the natural width for a clean sample, and the surface of the sample is determined to be contaminated when, as the result of comparison, the RR distribution width diverges from the natural width. The absence or presence of contamination on the microscopically rough surface of a sample can therefore be quickly and easily determined based on the RR of the reflective intensities of the s- and p-polarized light components.
