Title: Ic wiring method
Inventor: WAKI KAZUYOSHI
IPC: G06F17/50
Filed: 1989-10-27
Abstract: PURPOSE:To make it possible to select a path which is more suitable for the objective among a plurality of candidate paths and to select, e.g. the shortest path by not finishing seeking at the time point when the segments from both terminals meet at the first time, but continuing the seeking by the specified number of steps thereafter. CONSTITUTION:Segments A0 and B0 at a 0 level are made to extend from terminals A and B and guided to other blocks. Then whether the segments A0 and B0 at the 0 level are made to agree or intersected is checked. When both segments agree, the terminals A and B are connected with one segment. When both segments are intersected, the terminals are connected with the line which is bent by one time. In any case, the path is regarded as the shortest distance connecting both terminals A and B. The path is adopted, and the seeking is finished at this time. For example, since A1 is not intersected with B0, the segment whose seeking can be continued is selected among the generated segments at (n) levels based on the specified reference.

Title: Antithrombotic material
Inventor: NAKABAYASHI NORIO
IPC: A61L33/00
Filed: 1993-11-10
Abstract: PURPOSE:To provide an antithrombotic material to be used as medical materials, clinical test materials, or the like by grafting a specific hydrophilic monomer onto the surface of a polymer having a halogen atom or an alkyl halide group. CONSTITUTION:A monomer having a phospholipid polar group is grafted onto a polymer having a halogen atom or an alkyl halide group. Specifically, a basic polymer having a halogen atom or an alkyl halide group (e.g. polyvinyl chloride) is treated with a hydrosulfide (e.g. sodium hydrosulfide) to replace the halogen atom of the basic polymer with a mercapto group. Then the basic polymer with the mercapto group is grafted onto a monomer having a phospholipid polar group (e.g. 2-methacryloyloxyethylphospholylcholine) by free-radical polymerization via the mercapto group. The amount of the phospholipid polar group-containing monomer is normally 5-60mol% relative to the amount of the basic polymer.

Title: Etching method
Inventor: MURAI FUMIO
IPC: H01L21/027
Filed: 1985-12-16
Abstract: PURPOSE:To reduce damage to a substrate by electron beams, X-rays and ion beams, and to detect a positioning mark by applying a resin layer, a glass layer and an electron-beam resist in succession starting at an lower-most layer and conducting transfer and removal by specific operation. CONSTITUTION:A resin layer 8 containing a heavy element as a lowermost layer, a coatable glass film 9 in approximately 0.1mum thickness as an intermediate film and an electron-beam resist 10 as an uppermost layer are applied, a pattern formed by electron beams is transferred to lower layers in succession through dry etching, and an unnecessary section in a substance to be processed 2 is removed. The passage of incident electron beams 12 to a pattern forming region is prevented by the resin layer 8 containing the heavy element as the lowermost layer, thus reducing damage to a substrate 1. Since a projecting structure mark 11 is used as a positioning mark, the thickness of the resin layer 2 containing the heavy element is thinned extremely in the mark section, thus sufficiently detecting a signal from stepped structure by electron beams 13 for detecting the mark.

IPC: C23C14/56
Filed: 1990-10-19
Abstract: PURPOSE:To uniformize the thicknesses of a vapor deposited film in its transverse direction by detecting the transverse thickness distribution of the vapor deposited film right after the vapor deposition on the surface of a material to be deposited by evaporation at plural points and individually changing the opening degrees of plural shutters according to the detected values thereof. CONSTITUTION:The material 12 to be deposited by evaporation is made to travel in a vacuum chamber 11 and the material 6 for vapor deposition in a crucible 7 is heated to evaporate by a heater 8 to form the vapor deposited film on the material 12 to be deposited by evaporation. The thicknesses in the transverse direction of the vapor deposited film right after the vapor deposition are detected by plural film thickness detectors 10 at this time. The deviation  T between the set film thickness and the film thickness detected by the film thickness detectors 10 is calculated by film thickness deviation computing elements 14. Shutter opening degree computing elements 15 execute proportional integral control in accordance with this deviation  T to calculate a command value (r) for shutter positions and applies this value to motors 16. The motors 16 individually control the opening degrees of the plural shutters 9 to prescribed opening degrees in accordance with this position command value (r). The thickness of the vapor deposited film of the material 12 to be deposited by evaporation is uniformized in its transverse direction in this way and the quality of the material 12 to be deposited by evaporation is improved.
