Title: Method of inspecting fine pattern
Inventor: HONDA TOSHIYUKI
IPC: G03F1/84
Filed: 1985-02-27
Abstract: PURPOSE:To easily observe the roughness of the edge of a submicron pattern, by performing sputtering to make a thin metal film on the pattern, and thereafter performing electrolytic plating to deposit a metal to increase the roughness of the edge of a fine pattern. CONSTITUTION:When a submicron pattern 2 is made on a semiconductor substrate 1 by dry etching, the edge of the pattern has a roughness of about several hundreds Kt. A thin film 3 of Au is then made on the whole surface of the side of the substrate 1 by sputtering so that the film corresponds to several tens Kt. Au 4 is then deposited by electrolytic plating as the thin film 3 of Au is used as an electrode. At that time, an electric field is concentrated on the projections of the edge of the pattern2 to deposit more Au on the projections, and is so weak on the curves of the edge as to deposit less Au on the curves. As a result, the roughness of the edge is increased. After that, the roughness of the edge of the pattern 2 is observed by a scanning electron microscope.

Abstract: PURPOSE:To equalize the temperature of the inside of a core tube by mounting a heating element, which is bent at end sections along an axis and has a connecting section, to the outer circumferential wall of the core tube in a vertical type furnace for thermally treating a wafer, surrounding the heating element by a partition and an outer cylinder and each generating an upward air flow on the surface of the heating element and a downward air flow between the partition and the outer cylinder. CONSTITUTION:A heater wire 12, which runs parallel in the longitudinal direction of a core tube 11, is bent at upper and lower end sections and is connected directly, is fitted to the outer circumferential surface of the core tube 11 constituting a vertical type furnace for thermally treating a semiconductor wafer. The outer circumference of the core tube is surrounded by a cylindrical partition 14 consisting of alumina, and the outside of the partition 14 is surrounded by an outer cylinder 13 similarly composed of alumina while keeping a regular interval. Consequently, an upward air flow generated on the surface of the heater 12 is turned back at the upper ends and falls into a clearance between the partition 14 and the outer cylinder 13 as a downward air flow, and the process is repeated and the internal temperature of the core tube 11 is equalized. Accordingly, the annealing effect of the wafer is improved.

Title: Carbonaceous material, manufacture thereof, and non-aqueous electrolyte battery using thereof
Inventor: KOMARU TOKUO
IPC: H01M10/05
Filed: 1990-02-21
Abstract: PURPOSE:To increase a doping quantity to lithium and, applying to a negative electrode, to increase charging/discharging capacity by adding a specific quantity of a boron compound when an organic material is carbonized into a carbonaceous material. CONSTITUTION:An organic high molecular compound such as a phenol resin, an acrylic resin and the like is used for an organic material, and a boron oxide, boron and the like are used for a boron compound. The boron compound in a state of aqueous solution is added to a system of reaction for carbonization of an organic compound to make a boron content of the carbonized organic material 0.1-2.0 weight percent. When the boron compound content is less than this range, a doping quantity to lithium can not be effectively increased, while more content thereof increases internal resistance. The doping quantity to lithium is thereby increased and application to a negative electrode increases charging/discharging capacity.
