摘要:
A microwave plasma enhanced CVD method and apparatus wherein a microwave is applied, after expanded, over a greater area than the area in which a desired thin film is to be formed. With this arrangement, uniform microwave application is assured to produce uniform plasma over a wide area. This enables realization of a large size liquid crystal display.

A resist is peeled without leaving a residue after peeling, by bringing a resist-peeling liquid comprising a primary aliphatic amine of 2-6 carbon atoms into contact with the surface of an etched novolak positive photoresist, and removing the resist-peeling liquid containing the thus peeled resist from the surface of the etched resist. The used resist-peeling liquid can easily be recovered and regenerated.

A liquid crystal display device is produced by effecting in the course of its production steps a resist-peeling method including the steps of (a) changing the quality of a resist layer on a substrate, (b) contacting the changed resist with a liquid containing 2-amino-1-ethanol, and (c) removing the liquid containing the thus peeled resist from the surface of the etched resist, and optionally, (d) regenerating a liquid containing 2-amino-1-ethanol by distillation from the liquid used in step (c) and reusing the regenerated liquid in step (b).
摘要:
A liquid crystal display device is provided with a pair of substrates which are arranged to face each other in an opposed manner and a liquid crystal layer which is sandwiched between main surfaces of a pair of substrates. On the main surface of one of the pair of substrates which faces the liquid crystal layer, pixel regions including switching elements, pixel electrodes which are connected to the switching elements and a protective film which is disposed at liquid crystal layer side of the switching elements are formed. In such a liquid crystal device, the protective film is formed by laminating the plurality of material layers which include at least a first material layer and a second material layer which is arranged closer to the liquid crystal layer side than the first material layer. Further, the second material layer exhibits resistivity which is lower than resistivity of the first material layer and higher than resistivity of silicon or semiconductor layers which constitute channels of the switching elements. Due to such a constitution, the image retention which is generated on a display screen of the liquid crystal display device can be reduced.

A sputtering method and apparatus for use in forming thin films on a substrate. The power output of a sputtering power source is periodically changed to a high level power and a low level power, and each film is deposited to a thickness corresponding to the integrated value of the high level power, whereby a desired thickness can be obtained in any of multilayer films having mutually different film thickness ratios.

摘要:
An organic thin film consisting essentially of an organic compound is formed on a substrate surface by vacuum vapor deposition by exposing the organic compound as a vapor source to a laser beam having an energy level corresponding to that of the chemical bond of the organic compound, thereby sputtering the organic compound onto a substrate surface in vacuum and forming the organic thin film thereon. When a light or radiation-sensitive organic compound is used as the vapor source, a light or radiation-sensitive resist film is formed. The thin film thus formed retains the original chemical structure of the vapor source, and has a good flatness. Resolvability of resist film is improved owing to the absence of pin holes and particulate matters. A resist film having a higher sensitivity and a better contrast is formed by heating the substrate during the vapor deposition.

摘要:
A method of manufacturing an LCD device which includes a gate line having an effective display area which includes an aluminum alloy layer and an aluminum oxide layer. The gate line also includes a gate terminal portion which is made up of the same aluminum alloy layer with a molybdenum alloy layer formed thereon. To form this structure, an insulating substrate of the LCD device, with the laminated structure of the aluminum alloy layer and the molybdenum layer, is immersed in an electrolytic solution. During the immersion, the molybdenum layer is etched off the aluminum alloy in the effective displaying area, while the etching is prevented in the gate terminal area by a protective layer. Following this, the aluminum oxide layer is formed over the aluminum alloy in the effected display area while the device is still immersed in the electrolytic solution.
摘要:
A thin film transistor structure for use in driving liquid crystal display elements has a semiconductor active layer, a control electrode layer underlying the active layer with an insulating layer interposed therebetween and first and second main electrode layers formed on or above the active layer in a spaced relation with each other to define a channel in the active layer in cooperation with the control electrode layer between the main electrode layers. The active layer has a first peripheral edge portion generally perpendicular to the direction of the channel and a second peripheral edge portion generally not perpendicular to the direction of the channel. The first and/or second main electrode layer extends over the first and/or second peripheral edge portion of the active layer such that at least a part of the first peripheral edge portion and/or at least part of the second peripheral edge portion of the active layer has its side face directly covered with the main electrode layer.
