Title: Preparation of silicon wafer
Inventor: HERUBERUTO GEEBERU
IPC: C30B31/02
Filed: 1996-10-07
Abstract: PROBLEM TO BE SOLVED: To directly use a diffusion film doped with a dopant at a high concentration for diffusion with out stripping off a silicon material after cutting off a silicon wafer by forming the diffusion film on one surface of the wafer and a neutral film doped with the dopant at a low concentration on the other surface of the wafer in a succeeding diffusing process. SOLUTION: Each silicon wafer 1 has two surfaces formed by a wire saw. A diffusion film 2 is formed on one surface of the wafer 1 and a neutral film 3 is formed on the other surface. The film 2 is composed of a binder and a dopant. The concentration of the dopant is selected as high as possible so as to increase the concentration of the dopant in the wafer 1. The neutral film 2 is substantially composed of a binder. In is ideal to lower the concentration of the dopant in the film 2 to such a level that the silicon wafer 1 is not doped with the dopant.

Title: Production of reticle
Inventor: NOZAKI KATSUHIRO
IPC: G03F1/00
Filed: 1987-10-23
Abstract: PURPOSE:To reduce the multireflection harmful to pattern formation by forming an antireflection coating on all of the surface where a pattern will be formed on a reticle base and forming a pattern on the surface of this antireflection coating. CONSTITUTION:The light from a light source 1 is condensed by a condenser lens 2 and is projected to a reticle 3, and this light is reduced and projected to the surface of a wafer 5 through an image forming lens 4 with, for example, 1/5 magnifications to form the pattern of the reticle 3. With respect to the reticle 3, an antireflection coating 7 is applied on all of the surface of a base 6 and a pattern 8 is formed on the surface of this coating 7. Consequently, though the exposure light reflected on a lens 4 or the surface of the wafer 5 in a reduction projection exposure device reaches the surface of the reticle 3, the exposure light is not reflected on the surface of the reticle base by the action of the antireflection coating 7 and the harmful multireflected light is not generated through the reticle 3. It is more preferable that the antireflection coating is formed on all of the surface opposite to the pattern forming surface, as well.

Title: Colorant for plastic and colored molding
Inventor: HISHIDA SHINGO
IPC: B29K103/06
Filed: 1993-10-25
Abstract: PURPOSE:To obtain the title high-performance colorant which scarcely forms a weldline even when it has a relatively large particle diameter. CONSTITUTION:The surfaces of particles having a maximum outside diameter of 10mum to 1.5mm, having surface gloss, and made from for example, a metal powder are coated with a dispersant comprising a surfactant (e.g. metallic soap), a wax comprising a low-molecular-weight resin and a fatty acid lubricant such as a higher fatty acid (e.g. stearic acid) and a coupling agent or a plasticizer to obtain the title colorant. Altenatively, this colorant is combined with a pigment powder or an inorganic filler surface-coated with a dispersant or both to form a mixture used as a colorant. A molding colored with either of these colorants is freed from any weldline.

Title: Inner plug and cap of liquid spout container
Inventor: SAEKI MASATOSHI
IPC: B65D41/34
Filed: 1999-09-20
Abstract: PROBLEM TO BE SOLVED: To reduce force required for cutting a coupling of an outer cylinder and starting tear of a cut groove by inclining a cut of the outer cylinder, by forming a tab into a trapezoid having a gradient side corresponding to the inclined cut and an upper end of the outer cylinder as a longer side, and by providing a finger hook at an intersection of the gradient side and the longer side. SOLUTION: A notch 13 is provided at a predetermined position of an outer cylinder 6, and an upper part of a coupling 12 is made into a gradient cut 14 extending slantly. A form of a tab 16 is formed to be a trapezoid having an upper end rim of the outer cylinder 6 as a longer side and the gradient cut 14 side as a gradient side, while an intersection of the gradient side and the longer side is an arcuate finger hook 17. Since the tab 16 is formed in a trapezoidal form having the gradient cut 14 side as a gradient side and the upper end rim of the outer cylinder 6 as a longer side in this constitution, a distance from the finger hook 17 to the coupling 12 is longer than the case where a cut is provided longitudinally on the outer cylinder 6. Therefore, even if force for pulling out the finger hook 17 is equal, larger tearing force may function to the coupling 12.

Title: Bump electrode of semiconductor chip and method of mounting it on substrate
Inventor: IGUCHI YASUO
IPC: H01L21/60
Filed: 1990-10-05
Abstract: PURPOSE:To facilitate deformation by stress and buffer the unevenness in heights of bump electrodes by a method wherein the bump electrode of a semiconductor chip is made of metal deposited into needle-shapes. CONSTITUTION:An Sn electroplating 37 is applied with alkano-sulfonic acid solution. The plating is applied with a current density of, for instance, 0.6A/dm<2> for 30 minutes and, at that time, the length of needle-shaped deposition is about 10mum. When the current density is reduced to a half, i.e., 0.3A/dm<2>, needle-shaped deposition is hardly observed. The current density may be 0.5-0.7A/dm<2>. Further, if a current application time is extended, the length of the needle-shaped deposition can be increased. After the needle-shaped deposition is deposited by the Sn electroplating 37, An Au plating 38 is deposited to have a thickness of 1mum. Then a photoresist layer 36 is removed and Al films 34 which are unnecessary feeder films are removed by etching to obtain a needle-shaped bump electrode 39.

Title: Coding method of binary data array
Inventor: RAZUMITSUKU KARABETSUDO
IPC: H03M7/14
Filed: 1990-10-05
Abstract: PURPOSE: To obtain a binary data string code whose output is constant, even when a channel output signal performs phase shift by 180 deg. by encoding a binary data string into a binary code word string which has zero power spectrum value to zero frequency by means of a finite state machine. CONSTITUTION: Input data of in the form of a binary symbol string is transferred from a bus 10 to a finite state machine encoder 11 which has 8/10 encoding ratio, and binary code symbol series which becomes an input to a dual code (1-D) partial response channel 12 is generated. The code has zero power spectrum with respect to zero frequency in a transmission function of the channel 12. The channel output series which is generated by the channel 12 undergoes Viterbi decoding by a Viterbi decoder 13. The Viterbi encoder 13 calculates the most probable code series from the channel output series. Thereby, it has no relation to 180 deg. phase shift of a channel output signal. It excludes a differential encoding/decoding circuit that is typically needed to adapt a phase constant code.

Abstract: PURPOSE:To contrive the improvement of the talkie service by storing mobile information at a controller when a cordless telephone set dials a predetermined special number and then dials mobile information and sending the mobile station to a called telephone set when a call comes from the cordless telephone set. CONSTITUTION:When a cordless telephone set 30 moves from a zone 11 to a zone 12, the cordless telephone set 30 dials a predetermined special number to dial an arrival schedule time from the moving zone number to the zone.
