Title: Liquid crystal display device
Inventor: OTANI KATSUYA
IPC: G02F1/1339
Filed: 1985-06-26
Abstract: PURPOSE:To prevent the failure of a thin film transistor by mechanical stress and to make an easily visible display by forming spacers to the region except the prescribed part of one of substrates forming a display device by mask exposing and developing. CONSTITUTION:A liquid mixture composed of a spacer material, photosensitive resin and soln. is coated over the entire surface to one of the transparent counter electrode substrate 8 having a counter electrode 7 or the thin film transistor (TFT) array substrate 6. The spacers 11 having a desired height are exactly formed to the region except the TFT part, multi-layered wiring part and effective display part when the coating is subjected to mask exposing and developing. A liquid display device is formed when these substrates 6, 8 are press stuck to each other. The exertion of the stress during the press sticking is thereby obviated and the failure of the TFT is prevented. The easily visible display with the good brightness accuracy is thus made by the spacers having the desired exact and uniform height.

Title: Palladium fine line for semiconductor element
Inventor: UNO TOMOHIRO
IPC: C22F1/00
Filed: 1993-06-10
Abstract: PURPOSE:To obtain a characteristic same as or more than a gold alloy fine line in the overall bonding property by making the tensile extension percentage in a palladium fine line within a specific scope. CONSTITUTION:This palladium, fine line for semiconductor element has the tensile extension percentage in the line direction within the scope 5 to 14%. The reason to set the above tensile extension percentage at 4 to 15% is like this. When the extension percentage is less than 5%, the strength is too high, and a poor connection or an unstable ball formation are generated in the second bonding condition and when it is more than 15%, the wire strength is lowered and a wire bending following the reduction of the linear advancing property of a loop immediately after the bonding is made remarkable. By using such a palladium fine line as a bonding wire, a good connection with a lead frame, and a continued bonding property can be improved.

IPC: H01L27/146
Filed: 1988-06-07
Abstract: PURPOSE:To enhance the resolving power to a level nearly equal to that of a black-and-white image readout device by installing optical sensors which have been laminated doubly in a direction perpendicular to a photodetecting face. CONSTITUTION:Optical sensors A, B which have been laminated doubly in a direction perpendicular to a photodetecting face are formed. The optical sensor A formed in an upper layer functions as an ordinary optical sensor where a color filter has not been attached. The optical sensor B formed in a lower layer functions as an optical sensor where a color filter transmitting a red-based color has been attached. The optical sensor A functions as a color filter transmitting the red-based color with reference to the optical sensor B. When a signal obtained from the optical sensors A, B is operated and processed, a color signal is obtained. Then, the color signal covering one picture element can be obtained from a space covering one optical sensor on the photodetecting face. By this setup, the resolving power can be enhanced to a level nearly equal to a black-and-white image readout device.
