Abstract: PURPOSE:To detect a feature point at a high speed by dividing an input binary pattern into blocks and detecting the feature point through calculation of quantity of the feature of each block and from the connecting relation between adjacent blocks. CONSTITUTION:A binary pattern supplied from a pattern input device 1 is stored in a pattern memory 2 and all bits arrayed in the memory 2 in accordance with the x-y coordiates are divided into blocks. Then quantity of the feature is calculated for the pattern region within each of divided blocks. A quantity of the feature calculating processor 6 obtains the form of the pattern region within each block and the information on the connecting relation between adjacent blocks from quantities of plural different feature and stores them in a data memory 5. A code processor 7 adds a code to each quantity of feature and stores it into a coded pattern memory 8 in the form of a code of the corresponding block. A feature point detecting processor 9 detects the feature points of a pattern by means of a coded pattern.

Title: Plasma etching
Inventor: NAWATA MAKOTO
IPC: H01L21/3065
Filed: 1999-01-08
Abstract: PROBLEM TO BE SOLVED: To provide a method for performing plasma etching on an oxide film, which can suppress the decrease in the etching rate of the oxide film and provide high selectivity to an underlying silicon film. SOLUTION: In a microwave plasma etching apparatus, a constituent member, e.g. an electrode cover 10 of a vacuum container 4 for generating plasma is made of silicon carbide, and a radio frequency power is applied to the silicon carbide. Thereby silicon or carbon ions as constituent components of the silicon carbide are sputtered. Also the reaction of silicon ions with fluorine ions causes formation of carbon fluoride. The reaction with the sputtered silicon or carbon ions causes fluorine ions or fluorine atoms as silicon reactive species to be decreased, thus decreasing an etching rate of an underlying silicon film. Carbon fluoride prepared through the reaction with fluorine ions is a reactive species, which suppresses the etching of the underlying silicon film and selectively etches an oxide film.

Filed: 1991-01-14
Abstract: PURPOSE:To efficiently perform burr removing work without damaging the surface roughness of a part by removing the burr bonded to a product by cyclically vibrating the product through the fluid brought into contact with the product. CONSTITUTION:A burr removing apparatus is constituted of a mounting part 2 mounting a product 1 from which a burr must be removed in a freely vertically and horizontally movable manner, the high pressure water jet nozzle 3 fixed in opposed relation to the mounting part 2 and a rotary head 4 making the injection of water to the product 1 from the nozzle 3 intermittent. The rotary head 4 is formed by providing notches 6 to the peripheral part of a disc 5 at four places crossing each other at a right angle and made freely rotatable at a variable speed by a motor 7. That is, by allowing the track of the high pressure water injected from the nozzle 3 to cross the notches 6 of the rotating disc 5, the injection of the high pressure water to the product 1 is made intermittent. The frequency making the injection of high pressure water intermittent is adjusted to the inherent vibration frequency of the burr to the product 1 by variably controlling the number of rotations of the motor 7. By this constitution, burr removing work can be efficiently performed.

Title: Method of deburring resin molded product
Inventor: UEDA NAOTO
IPC: H01L21/56
Filed: 1987-01-09
Abstract: PURPOSE:To make it possible to remove thin burr in the same bath without giving damage to a resin part, by immersing a resin molded product in aqueous solution, and alternately repeating the step for performing electrolysis of the aqueous solution with the metal part of the resin molded product as one electrode and the step for performing ultrasonic wave washing of the metal part in the aqueous solution. CONSTITUTION:A semiconductor device after resin sealing is immersed in NaOH solution 6 for a specified time period. With an outer lead 2 of the semiconductor device as, e.g., a cathode, at first, a DC voltage is applied. H2 gas 5 is yielded between the outer lead 2 of the semiconductor device and thin burr 4 by the electrolysis of the NaOH solution 6. Thus the thin burr 4 is removed. Then a high frequency signal is imparted to an ultrasonic wave vibrator 12 from an ultrasonic wave source 11 for a specified period, and ultrasonic wave washing is performed. Thus the electrolytic deburring and the ultrasonic wave washing are alternately repeated in a short period. Therefore a problem of obstruction to the yield of H2 gas bubbles, which are to be formed in the electrolysis, can be solved. The two steps can be performed in the same bath approximately at the same time.
