Filed: 1993-05-17
Abstract: PURPOSE:To prevent a void from being formed in a solder bonded part and to prevent a semiconductor chip from being tilted after its bonding by a method wherein a semiconductor- chip bonding face at a base material for semiconductor-chip bonding is made to protrude, a part corresponding to the central part of the semiconductor chip is formed to be high and the part is formed to be low as it advances toward a side part. CONSTITUTION:A base material 11 to which a semiconductor chip 1 is to be bonded is formed in such a way that its semiconductor-chip bonding face is made to protrude to the upper part than other parts, that a part corresponding to the central part of the semiconductor chip 1 is made highest and that the part is made low as it advances toward a side part. Then, when the semiconductor chip 1 is bonded to the base material 11 on which a protruding part 12 bas been former, a solder material 3 is heated and melted, and a molten part is spread gradually to a peripheral edge part from a point which comes into contact with the protruding part 12. As a result, a gas during a solder bonding operation is moved to a part corresponding to the side part from the part corresponding to the central part of the semiconductor chip 1 as the solder material is melted, and the gas is discharged to the outside from the peripheral edge part of a solder bonded part. Consequently, it is possible to prevent a void from being formed in the solder bonded part.

Abstract: PURPOSE:To detect magnetic fields in a broad range from a low magnetic field to a high magnetic field. CONSTITUTION:Magnetooptic elements 23a and 23b are overlapped so that the axes of easy magnetization 24a and 24b are intersected at a right angle to each other.

Incident linearly polarized lights 25a and 25b are emitted in such a way that the polarization planes are rotated by the Farady effect caused by the change in magnetized states of the magnetooptic elements. Therefore, the strength and the direction of the magnetic field can be found by observing the rotating angles thetaFa and thetaFb of the emitted lights.

Filed: 1992-05-08
Abstract: PURPOSE:To provide a light-emitting diode array which can reduce attaching of a polycrystal line layer to a light-emitting layer by optional epitaxial growth of III-V chemical compound semiconductors formed on a silicon semiconductor substrate. CONSTITUTION:III-V group chemical compound semiconductors composed of GaAsP are laminated, by optional epitaxial growth method, on the main surface of a silicon semiconductor substrate 1 of a region, which is surrounded by an insulating film 2 bonded on the silicon semiconductor substrate 1. As a result, PN junction is formed. For a light-emitting layer surrounded insulating films as single unit light-emitting diode, the area ratio of the light-emitting layer to the area of the insulating films is set to less tan 0.44. Therefore, cluster is difficult to be generated, and a polycrystal line layer is difficult to be formed on the light-emitting layer. As a result, light-emitting characteristics of the light-emitting diode can be good.
