IPC: H01L23/50
Filed: 1987-03-20
Abstract: PURPOSE:To prevent the generation of resin crack by heat in case of mounting a semiconductor device on a printed substrate by forming the section of a tab at a tab reverse element placing surface in a shape in which the thickness of the tab is gradually increased from both ends of short axis direction toward the center. CONSTITUTION:A tapered surface 14 is so formed at a reverse element placing surface 2a of a tab 2 that the sectional shape of the tab 2 is gradually increased in thickness from both ends 2e of the tab 2 in a short axis direction toward the center. Since the angle of the end 2e of the tab 2 of this sectional shape in the short axis direction becomes 90 deg. or larger, a stress concentration rate can be reduced. Accordingly, since the thickness of resin is increased to provide a stress reducing effect and it can prevent a local stress concentration, it can prevent the resin from cracking from both ends 2e of the tab 2 in the short axis direction.

Abstract: PURPOSE:To detect with a higher accuracy a pressure eliminating the effect of the ambient temperature by providing a diaphragm for compensation together with a pressure-receiving diaphragm, in a pressure sensor utilizing the piezoresistance effect of a semiconductor. CONSTITUTION:A rectangular pressure-receiving diaphragm 11 and a diaphragm 12 for compensation are formed by an anisotropic etching of the thinner part of a single crystal semiconductor substrate 10 of silicon, etc. The substrate 10 is fixed to bodies 31, 32 of a glass, etc. Then the recessed part 42 at the lower part of the pressure-receiving diaphragm 11 is made to be of an atomospheric pressure PO and the recessed part 43 at the top part to be of a measuring pressure PM. On the other hand a recessed part 40 under the diaphragm for compensation 12 is made vacuous and a recessed part 41 at the top to be of an atomosphric pressure PO. And the pressure applied on the diaphragm is detected with gauge resistors 21-24 provided on each diaphragm 11, 12. The temp. dependability of gauge resistance is the same on both the diaphragms 11, 12. Consequently by correcting the gauge resistance of the pressure-recieving diaphragm with the gauge registance of the compensation diaphragm, a pressure is detected with a higher accuracy.

Title: Defocusing detecting device
Inventor: HATTORI SHUZO
IPC: G02B7/28
Filed: 1990-03-16
Abstract: PURPOSE:To obtain sufficient defocusing detection sensitivity by a compact optical system by forming an annular photoelectric conversion surface and further dividing it equally into four parts. CONSTITUTION:Reflected light from an object surface 1 is made incident on a photodetecting element 4A by passing through an aspherical lens 2a, a spherical lens 2, and a cylindrical lens 3 and the element 4A is arranged at a focusing position where circular converged light from the lens 3 is photodetected when the object surface 1 is at a specific position. The lens 3 deforms the converged light into an elliptic shape as defocusing is caused. The element 4A is formed annularly and divided equally into the four parts 4-1 to 4-4, the internal diameter 2RB is made less than the external diameter 2RS of the circular converged light at the time of focusing, and the respective parts 4-1 to 4-4 are connected to a differential amplifier to output a defocusing detection signal. Consequently, if defocusing is caused, the ratio of the projection area of the elliptic converged light on a divided surface in the major-axis direction and the projection area in the minor-axis direction becomes large, so that defocusing detection sensitivity can be increased.
