Filed: 1990-04-27
Abstract: PURPOSE:To form a fine resin pattern of a small width and a large thickness with high resolution by a method wherein the fine pattern is formed by electrodepositing a resin on an open part of a primary-coat metal layer. CONSTITUTION:A primary-coat metal layer 2 is formed all over an insulating substrate 1. A thin layer of a photosensitive resin 3 is applied all over the primary-coat metal layer 2 and selectively exposed to light from above to be developed to a photoresist pattern of a recording electrode pattern. A 20-30mum resin is applied on a photoresist-free part on the primary coat metal layer 2 by electrodepositing to form a fine pattern 4. The photoresist is removed. A recording electrode 5 is formed on the open part on the primary-coat metal layer by plating. The fine pattern 4 and the primary-coat metal layer 2 other than the recording electrode forming part are removed. The photosensitive resin 3 is so thin as to be formed patternwise with high resolution, and the small-width, thick, fine resin pattern can be formed with high resolution. Thus, a high-accuracy recording electrode can be formed. The resin formed by electrodepositing strongly adheres to the primary-coat metal layer, thus never releasing therefrom, and the recording electrode can be efficiently formed with high accuracy.

Title: Floating preventing circuit
Inventor: HORIKOSHI KENGO
IPC: G06F13/36
Filed: 1989-04-27
Abstract: PURPOSE:To prevent the generation of floating by connecting a function block having an inverter for inputting the data of a data bus, and a second inverter for inputting its output and outputting it to the inverter and the data bus. CONSTITUTION:In the case one is selected from plural data signals, this data passes through a data bus 3 and flows into function blocks 5, 6. The data passing through an inverter 7 is brought to positive feedback by an inverter 8, therefore, the block executes an operation for latching the data. When the driving capacity of a function block 4 is made large enough against the inverter 8, even if a competition is generated, the driving capacity of the block 4 is always superior, and the data is latched to the block 6. Subsequently, when all the blocks 4 are set to a high impedance state, this time, on the contrary, the data flows into the data bus 3 from the inverter 8. In such a way, even if all the function blocks become a high impedance state, it does not occur that the block 5 becomes gate floating, and a malfunction can be prevented.

Title: Manufacture of x-ray mask
Inventor: SOGA TAKASHI
IPC: G03F1/68
Filed: 1987-05-08
Abstract: PURPOSE:To make an etch-opening with fidelity to the shape of an an etching mask while cutting down the etching time by using a substrate wherein only a region to be etched away is previously thin filmed. CONSTITUTION:A thin film 5 made of X-ray transmitting material is formed on a substrate 4 made of a single material and then a part of the substrate 4 is etched away to form a mask for X-ray lithography. At this time, silicon in thickness exceeding 1mm is used for the substrate 4 while the central pattern forming region only is formed into thin film in thickness of 10-100 mum by machining or chemical processing. Thus, the bending amount of substrate 4 before and after the etching away process of substrate 4 can be restricted to low level by the action of thick frame around the substrate 4 to cut down the required time for the etching away process of substrate 4. Through these procedures, an etch-opening with fidelity to the shape of etching mask can be made.
