  • Patent number: 6664549
    Abstract: In a wafer chuck for flatly vacuum-chucking a semiconductor wafer (11) supported by support pins (15) such that a pressure in a suction chamber (13) surrounded by an external wall (12), the upper surface of the external wall (12) is formed to be lower than the upper surfaces of the support pins, and the upper surface of the external wall (12) does not pressure the semiconductor wafer (11), a distance (L1) between the external wall (12) and closest support pins (15a) is up to 1.8 mm, and an alignment pitch. (L2) of the support pins (15) aligned inside the closest support pins (15a) to the external wall (12) is not more than 1.5 times of the distance (L1) between the external wall (12) and the closest support pins (15a).

  • Patent number: 5155060
    Abstract: A photoresist of sufficient thickness to fill a scribe line is applied to an entire substrate. The photoresist is exposed through a photomask having a pattern corresponding to the scribe line and then developed. A photosensitized gelatin is applied by spincoating on the flat substrate obtained in this process, pattern and then dyed, to obtain a color filter array.

  • Patent number: 5079595
    Abstract: A method for manufacturing an organic semiconductor thin film (24) having an improved characteristic as a semiconductor is provided. A phthalocyanine compound having amino groups is mixed with stearic acid to form a bonded substance capable of being dissolved in an organic solvent. Then, an organic solution is made by dissolving this bonded substance in the organic solvent. By developing this organic solution on a water (20) surface, the thin layer (23) of this bonded substance is formed on the water (20) surface. Thereafter, this thin layer is moved onto a substrate (30) and accumulated to be deposited on the substrate (30). Next, the stearic acid is volatilized and removed from the above described thin film (23) deposited on the substrate (30) by baking the whole substrate. The thus structured organic semiconductor thin film (24) is used as a semiconductor material such as a photoelectric transfer device, a gas sensor, a transistor and the like.
