Title: Semiconductor light emitting device
Inventor: ISHII MITSUO
IPC: H01S5/00
Filed: 1989-03-08
Abstract: PURPOSE:To contrive miniaturization and improvement in reliability by forming a protrusion after surrounding a place at which a block for radiation of heat is installed at the mainface of a stem. CONSTITUTION:A protrusion 10 is mounted so that the protrusion may surround a block 2 for radiation of heat that is soldered at the center of the main face of a stem 1; besides, it may hold a position inside of the welded part of a cap 7. The protrusion 10 prevents a surplus soldering flux from flowing out up to the welded part of the cap 7 on the occasion of soldering the block 2 to the stem 1. As the protrusion 10 prevents effectively the soldering flux from spreading over surroundings, both stem 1 and cap 7 diameters can be reduced and then this device is miniaturized. Further, concentration of the surplus soldering flux into the surroundings of the block 2 renders close contact strength between the block 2 and the stem 1 more secure and then high reliability is obtained.
