Title: Semiconductor device
Inventor: YOSHIMORI KENZO
IPC: H01L23/28
Filed: 1988-02-29
Abstract: PURPOSE:To improve adhesion between a package and a chip and leads and to prevent the yield of cracks, by providing rectangular grooves having U-shaped cross sections in the upper and lower surfaces of a resin package, and dispersing thermal stress in molding and mounting on a board. CONSTITUTION:Rectangular grooves 10 having U-shaped cross sections are molded as a unitary body in the upper and lower surfaces of a resin package 7 when molding is performed. Therefore, thermal contraction stress that is generated in molding of the package 7 is divided into smaller parts and dispersed with the grooves 10, and strain hardly occur. Thus, adhesion between a semiconductor chip 5 and a lead frame 4 and the package 7 is improved. Internal stress that is concentrated in the vicinities of the end parts of the chip 5 and a die pad 3 is decreased. Thermal expansion stress when a device 1 is mounted on a printed board is decreased. Passivation cracks and package cracks are not yielded. In this way, the high quality, highly reliable semiconductor device is obtained.

Title: Calibrating method of mask position
Inventor: MITSUSHIERU AARU RAUFU
IPC: G03F9/00
Filed: 1985-03-06
Abstract: PURPOSE:To enable the use of a calibration plate of which the lattice point position is unknown by moving grating plates in the 1st and 2nd directions associated with a prescribed parameter, measuring the points within the grating and minimizing deviation in the congruence of the images of the respective gratings of the calibrated coordinate system. CONSTITUTION:The corner A of a calibration plate 45 which makes rigid motion is fixed at the corner of the frame 46 of a wafer stage 47 in contact therewith (the 1st direction) and the points on the plate 45 are detected. The 1st, 3rd and 4th directions determined similarly with the corners B, C, D of the plate 45 are associated to the 1st direction by the rotation around the fixed points F2, F3 and F4. The position at the point of a measuring space for calibration (-X, -Y) is expressed by the specific finite polynominal with respect to instrument coordinates and the parameter is so selected to maximize the quantity at which each grating in the 2nd, 3rd and 4th directions by the rigid motion coincides with the grating in the 1st direction. The number of the grating points is thus so selected that the number by the independent equations is larger than the unknown number.

Abstract: PURPOSE:To make a strut driven straight at the time of driving the strut into the ground. CONSTITUTION:A strut 12 has a both-sided tapered forward end part 12a blocked up in such a manner as to become narrower at the tip. The both-sided tapered forward end part 12a is formed by crushing the vicinity of the tip of a round steel pipe from both sides in the diametral direction in such a manner that the central part is recessed, and then crushing the vicinity of the tip in the direction right-angled to the crushing direction. A sheathing steel plate 11 has an opening part 14 nearly rhombic in top view, which is formed by slit punching or bending one rectangular steel plate. The sheathing steel plate 11 is erected on the ground, and the strut 12 is inserted in the opening part 14 to be driven.

Abstract: PURPOSE: To improve electromagnetic transducing characteristics and running durability by specifying the ratio of the center line average roughness of the surface of a magnetic layer on a nonmagnetic substrate in the transverse direction to that in the longitudinal direction measured with a contact needle type surface roughness gauge. CONSTITUTION: In the magnetic recording medium obtd. by forming at least one magnetic layer on a nonmagnetic substrate, the ratio (Ra2/Ra1) of the center line average surface roughness Ra2 of the surface of the magnetic layer in the transverse direction to that Ra1 in the longitudinal direction measured by 0.08mm cutoff with a contact needle type surface roughness gauge is regulated to 1.2-2.0. A means of regulating the ratio is not especially limited and the ratio is regulated, e.g. by selecting the shape of ferromagnetic powder and controlling the squareness ratio, selecting the shape of inorg. powder when a nonmagnetic layer based on the inorg. powder is formed, controlling the surface of the nonmagnetic substrate or selecting a coating method. When acicular ferromagnetic powder is used, the acicularity ratio is preferably reduced.  When platy ferromagnetic powder is used, the orienting property is preferably made high because the surface roughness of the magnetic layer in the transverse direction is increased.

Filed: 1989-02-27
Abstract: PURPOSE:To avoid the disturbance of a picture at the upper part of a reproduced pattern by providing a phase comparison means comparing the phase of an output of a frequency divider means with a phase of a horizontal synchronizing signal separated by a synchronizing separator means and controlling a sampling signal generating means so as to make the phases to be locked with each other. CONSTITUTION:A frequency divider circuit 52 of a phase locked loop circuit 50 frequency-divides an output of a voltage controlled oscillator 38 by 1/455. An output frequency of the frequency divider circuit 52 is nearly twice the frequency of a horizontal synchronizing signal. A phase comparator circuit 40 compares the phase of a reproduced horizontal synchronizing signal with a phase of an output of the frequency divider circuit 52 and controls the voltage controlled oscillator 36 so that they are phase-locked to each other. As a result, an output fs of the voltage controlled oscillator 36 is always phase-locked with the reproduced horizontal synchronizing signal even at field reproduction. An A/D converter 24 digitizes the reproduced picture signal in the timing of the output fs of the phase locked loop circuit 50 and its output data is written in a frame memory 26.
