Abstract
본 발명은 납땜시에 충분한 땜납 내열성을 가지며 포스트의 관찰 삽입 작업이 용이한 수지 밀봉 타입의 반도체 레이저 장치를 제공한다.The present invention provides a resin-sealed semiconductor laser device which has sufficient solder heat resistance at the time of soldering and is easy to observe and insert posts.
본 발명은 구성은 레이저 다이오드 칩(1)이 포토다이오드를 내장하는 서브 마운트(2)를 통해 고정되어 있고 고정 단부(3a)를 갖는 금속제의 주판(3)과, 이들 소자의 전기적 코먼용,레이저 다이오드용 및 포토다이오드용으로서 각각 와이어에 의해 전기적으로 접속되어 있고 주판(3)과는 분리되어 있는 3개의 금속제 포스트(4a,4b,4c)와, 상기 소자를 밀봉하고 있는 밀봉 수지(5)로 이루어지며, 이 밀봉 수지는 주판과 각 포스트를 서로 직접 접촉하지 않도록 고정하고 있으며, 또한 포스트의 단부는 이 수지로부터 돌출되어 있다.The present invention is constructed in that the laser diode chip 1 is fixed through a sub-mount 2 incorporating a photodiode and has a metal main plate 3 having a fixed end 3a, and an electrical common for these elements, a laser. Three metal posts (4a, 4b, 4c) electrically connected by wires and separated from the main plate (3) for diodes and photodiodes, respectively, and the sealing resin (5) for sealing the elements. This sealing resin fixes the main plate and each post so as not to directly contact each other, and the end of the post protrudes from the resin.
