    摘要: A composition for reducing development defects comprising an acidic composition containing, for example, a surfactant applied onto a chemically amplified photoresist coating formed on a substrate having a diameter of 8 inches or more. By this process, the surface of the resist is rendered hydrophilic and the formation of slightly soluble layer in a developer on the surface of the resist is prevented. In addition, by proper diffusion amount of acid from the composition for reducing development defects, the amount of reduction in thickness of the chemically amplified photoresist coating after development is increased by 10 Å to 500 Å in comparison with the case of not applying the composition for reducing development defects to form a resist pattern not having a deteriorated pattern profile such as T-top or round top.

    摘要: A starter which reduces the number of parts for a pinion rotation regulation and provides an accurate magnet switch operation. A concave portion is formed on the bottom side of a plunger to store a spherical body set on the rear end of a cord-shaped member, e.g., wire. A male screw and a fixing are used so that the length of the cord-shaped member is adjusted thereby. The length of the string-shaped member is adjusted so that the claw of the pinion rotation regulating member fits into the notch on the outer circumference of a pinion gear. Furthermore, the claw is fit into the notch via the wire when the plunger moves. The cord-shaped member may be replaced by a rod member disposed radially inside or outside the yoke.

    摘要: A vacuum vessel is provided in which the majority of a vessel wall including an annular wall portion (1) and a plate-wall portion (2) is formed of ceramic material such as silicon nitride, for example. To bond the plural wall members together, bonding faces having a surface flatness of not more than 1 .mu.m are prepared thereon, and then a ceramic powder bonding substance with an average particle diameter of not more than 1 .mu.m is interposed between adjacent bonding faces and subjected to heating. Because the generation of gas, such as hydrogen, from the wall of the ceramic vessel is reduced, extremely high vacuum can be generated and maintained in the interior of the vacuum vessel. Also, because the wall of the vacuum vessel has a high permeability with respect to a magnetic field and an electric field, the vacuum vessel can be used as a vessel in a particle accelerator that allows the high precision control of charged particles therein by means of an electromagnetic field.

    摘要: In a dicing method, a resin adhesive tape is stuck to one surface of a wafer mount frame, then a rubber plate is stuck to the tape from the open side of the frame. With the rubber plate stretched, an adhesive is sprayed over the rubber plate, whereupon a wafer is stuck to the rubber plate. A weight is placed on the rubber plate to extend it further, thus fixing the wafer to the frame. The thus mounted wafer is diced. Alternatively, a resin adhesive tape is stuck to one surface of the frame, then a thick adhesive rubber plate is stuck to the tape from the open side of the frame, whereupon a wafer with hard wax printed using a screen mask is stuck to the rubber plate. The thus mounted wafer is diced by cutting into it deeply. The cut wafer is soaked in a solvent for separation from the rubber plate. As a further alternative, screen mask printing is carried out on a wafer, and wax is coated over the wafer. A resin adhesive tape is stuck to one surface of a wafer mount frame, and then a thick adhesive rubber plate is stuck to the tape from the open side of the wafer mount frame, whereupon the wax-side surface of the wafer is stuck to the rubber plate. The mounted wafer is diced. The wafer is soaked in a solvent for separation of chips from the rubber plate.

    摘要: An impeller type pump has a pump body consisting of a front casing and a back casing. Each of the casings comprises a ceramic main portion and a protection member covering the main portion. The protection members of both the main portions are interconnected with each other at their confronting marginal portions through a continuous packing. Those confronting marginal portions of both the main portions which are adjacent to a pump chamber defined by inner surfaces of both the main portions are provided each with a plurality of concentrical rims loosely interdigitated to form a labyrinthine narrow passage restricting the flow of waste water therebetween, resulting in reduction of wear of the packing.
