Title: Semiconductor device
Inventor: HARADA SHIGERU
IPC: H01L21/02
Filed: 1988-06-28
Abstract: PURPOSE:To reduce the concentration degree of the compressive stresses to the corner sections of a semiconductor chip, prevent them from cracking, and increase the reliability by making the plane shape of the chip into a polygon with more sides than four and besides making each interior angle not smaller than 90 degrees. CONSTITUTION:A semiconductor chip 1 is fixed on a die-pad 2 and sealed with a molding resin material 5. Besides, the plane shape of the chip 1 is made into a polygon with more sides than four, and each interior angle is made to be not smaller than 90 degrees. Accordingly, the concentration degree of the compressive stresses applied to all the corner sections of the chip 1 becomes equal to or less than that of the compressive stresses applied to the corner sections whose interior angles are 90 degrees. This reduces the concentration degree of the compressive stresses to the corner sections by the stresses produced by the shrinkage of the molding resin material 5. As a result, it becomes possible to prevent the corner sections of a chip from cracking, and to obtain a molded resin-sealed type semiconductor device with high reliability.

Title: Correcting device of uneven illuminance in variable magnification copying machine
Inventor: KASAHARA NOBUO
IPC: G03B27/54
Filed: 1983-09-06
Abstract: PURPOSE:To correct illuminance irregularity on the photosensitive body of a slit exposure type variable magnification copying machine which varies in magnification by moving a lens in the optical-axis direction of an optical path through simple constitution without spoiling illumination efficiency greatly. CONSTITUTION:A correcting plate 11 which does not cut off luminous flux at life-size magnification and increases in the shielding amount of both end parts of the optical path between the surface of an original at an exposure optical system and the lens 8 as the magnification decreases is fixed to a machine frame at both breadthwise sides of the optical path. Consequently, the angle of incidence of luminous flux cut off by the correcting plate 11 to the lens 8 decreases according to the distance from the outermost point A of a slit to the center to reduce the width of a shade appearing on the lens, and the luminous flux is cut off only by a part of the correcting plate 11 at a point B, so the width Wb of the shade is further reduced. For the purpose, the position, shape, and size of the correcting plate 11 position are so predetermined that the ratio of the area of the shade on the lens to the area of an entrance pupil may be equivalent to the ratio of the uneven illuminance in the photosensitive body in the longitudinal direction of the slit at reduction magnification, correcting the uneven illuminance on the photosensitive body in the longitudinal direction of the slit.
