摘要	PURPOSE:To prevent a short circuit due to contact with a heat sink by a method wherein a stepped part whose height is equal to an electrode on the side of a board for a semiconductor laser or which is extremely small is formed on a pedestal for semiconductor mounting use. CONSTITUTION:A stepped part 15 which is equal to an electrode on the side of a board for a semiconductor laser 17 or whose height difference is within 1 mm is formed in a part on the side opposite to the radiating edge of the semiconductor laser 17 inside the surface of a pedestal 12 on which the semiconductor laser 17 is mounted. The stepped part 15 depends on the height of a heat sink 18 and the semiconductor laser 17. It is formed in such a way that the surface of the electrode on the side of the board for the semiconductor laser 17, the pedestal 12 and the stepped part 15 becomes nearly equal when the heat sink 18 and the semiconductor laser 17 are mounted. Consequently, a bonding wire which connects the semiconductor laser 17 to the stepped part 15 draws a gentle curve, and a bonding defect is eliminated. Thereby, it is possible to prevent a short circuit due to contact with the heat sink 18.
其他摘要	用途：通过一种方法防止由于与散热器接触引起的短路，其中在半导体激光器的基板上形成高度等于半导体激光器板侧电极的台阶部分或极小的台阶部分安装使用。组成：在半导体激光器17的板的侧面上的电极等于或者高度差在1毫米内的台阶部分15形成在与半导体激光器17的辐射边缘相对的一侧的部分内部底座12的表面安装有半导体激光器17。台阶部分15取决于散热器18和半导体激光器17的高度。它以这样的方式形成：半导体激光器板17侧的电极表面，基座12和阶梯式当安装散热器18和半导体激光器17时，部件15变得几乎相等。因此，将半导体激光器17连接到台阶部分15的键合线画出平缓的曲线，并且消除了键合缺陷。由此，可以防止由于与散热器18接触而导致的短路。
