Patent JP-H0425088-A (JP)
Title: Semiconductor laser
Inventor: UEHARA KUNIO
IPC: H01S5/00
Filed: 1990-05-16
Abstract: PURPOSE:To prevent a semiconductor laser chip from moving and lifting by prescribing the thickness of the gold electrode at the outermost layer fused with the heat sink of a semiconductor laser chip and permitting the area of a gold-tin solder part previously formed on the heat sink plane which fuses with the semiconductor laser chip to be the area obtained by multiplying the area of the semiconductor laser chip plane fused with the heat sink by a prescribed number. CONSTITUTION:The thickness of the gold electrode at the outermost layer fused with the heat sink of a semiconductor laser chip is less than 1mum. The semiconductor laser chip 1 is fused with the heat sink 2 by gold-tin solder 41 and the heat sink 2 is fused with a stem 3 by gold-tin solder 42. The area of the gold-tin solder 41 previously formed on the surface of the heat sink 2 before melting is 1.5 or less than the depositing area 11 of the semiconductor laser chip 1. When the semiconductor laser chip and the heat sink are fused, the area of the gold-tin solder 41 becomes larger than the area before melting by the solder flow and is thinned. Even when the gold-tin solder 41 is reheated at 280 deg.C or above, since the quantity of the solder absorbed between the semiconductor laser chip and the heat sink is lessened owing to the capillary phenomenon, the lifing quantity of the semiconductor laser chip is suppressed to be small.

IPC: H03G11/00
Filed: 1982-07-20
Abstract: PURPOSE:To prevent generation of spuriousness in an FM limiter amplifying circuit or the like, by using a balanced pi type MOS capacitor constituted with two MOS type capacitors connected in parallel. CONSTITUTION:The two MOS type capacitors 100, 200 are formed on a substrate 12, aluminum vapor-deposited layers 16a, 17b', and 16b, 17b are connected and led out as terminals A, B.
