Title: Production of active matrix liquid crystal display device
Inventor: OTA NORIO
IPC: G02F1/136
Filed: 1993-01-13
Abstract: PURPOSE:To easily produce a black matrix layer having sufficient light shieldability and pattern accuracy and low reflectivity. CONSTITUTION:Transistor elements 20 and display electrodes 7 are formed on a glass substrate 1 and a photoresist layer 15 of a negative type is formed over the entire surface of the substrate. This resist layer is subjected to back exposing from the rear surface side of the glass substrate 1 with the TR elements 20 as a mask and after the non-exposed parts of the resist layer 15 are removed by development, a hydrophilic resin layer 16 is formed over the entire surface of the substrate (Fig. (a)). This hydrophilic resin layer 16 is partly peeled away by lifting off the remaining resist layer 15 (Fig. (b)). The remaining hydrophilic resin layer 16 is impregnated with a metallic compd. to serve as a catalyst for electroless plating and is then subjected to the electroless plating, by which the hydrophilic resin layer is formed as the black matrix layer having the light shieldability.

Filed: 1987-01-30
Abstract: PURPOSE:To absorb a thermal stress at a resin mold and to prevent a soft error due to alpha rays by forming an uppermost protective film by using a metal. CONSTITUTION:A silicon nitride film as a lower-layer protective film 6 is formed by a CVD method so that it can prevent the moisture from penetrating into an upperlayer wiring part 5 and an interlayer insulating film 4; an aluminum film as an uppermost protective film 7 to absorb a stress is formed on the lower-layer protective film 6 in such a way that its thickness (normally about 2 mum) is 0.8-2 times the maximum difference in level at the lower-layer protective film 6. If the uppermost protective film composed of a metal is formed on the lower-layer protective film, a thermal stress to be exerted on the lower- layer protective film and the wiring part is absorbed and the yield rate for the manufacture is enhanced. In addition, it is possible to prevent alpha rays from penetrating thanks to the uppermost protective film; if this setup is applied to a DRAM, it is effective to prevent a soft error due to the alpha rays from being caused.

Abstract: PURPOSE:To perform the reading of a large number of and a various kinds of slips with high efficiency, by performing a character recognition processing after storing a quantized image on which reading control (FC) information is attached in a large capacity data storage device. CONSTITUTION:In a magnetic disk device 14, the FC information and the quantized image are stored as a sheet of slip image. A control part 11 takes out the quantized image at every slip unit from the magnetic disk device 14, and sends it to a character recognition processing part 16, and at the character recognition processing part 16, the FC information attached on the quantized image is read out first, and after information required for control being obtained, the quantized image is taken out, and the image of the slip is produced in a two-dimensional memory space. And by segmenting the character image of one character from the slip image, the character recognition processing is performed. In such a way, it is possible to perform the reading processing of the next slip without waiting the completion of the reading processing of one sheet of slip, and to improve working efficiency remarkably.
