Title: Light emitting diode with optical fiber
Inventor: MIZUTA YOSHIYUKI
IPC: G02B6/42
Filed: 1979-12-17
Abstract: PURPOSE:To prevent the stress transmission from an optical fiber to a light emitting surface of a light emitting diode by slightly expanding solder between a metallic base and a stem lead wire when the solder of the stem lead wire is solidified, and isolating between the light emitting surface and the optical fiber. CONSTITUTION:The end of the electric lead wire of a stem and the end of the optical fiber are placed on a plane, and the positional relationship between the light emitting surface 4 of a chip and the soldering base 5 to the stem lead wire of a subassembly is so set that the surface 4 is lightly projected. Solder expanding at desired rate when solidifying from molten state is molten beforehand at the lead wire of the stem. Then, when confirming that the light emitting portion makes contact with the optical fiber at suitble position, high frequency heating is interrupted. When the temperature is lowered and the solder at the stem lead wire 11 is solidified at this time, the solder is slightly expanded between the base 5 and the lead wire 11, the light emitting surface and the optical fiber are isolated at the corresponding amount, and it can prevent the stress from the optical fiber from transmitting to the light emitting surface of the diode.

Filed: 1978-12-27
Abstract: PURPOSE: To prevent short-circuit of the lead wire by absorbing connecting metal running out with a recess provided near the connection point of the lead wire when the lead wire having a plating layer on the surface thereof is connected to the electrode provided on the semiconductor element.  
     CONSTITUTION: A lead wire 13 having a tin plating 13' on the surface thereof is connected to a projected electrode 12 formed on a semiconductor element 1 employing a gold-tin eutectic alloy 15. In this process, a recess 17 is formed on the lead wire near a point surrounding the electrode 12 to absorb excess alloy running melted by heat during the connection through the surface tension. This eliminates metal grain mass which otherwise causes a short-circuit of the lead wire. Even if a lead wire having a thick plating layer is used to improve the wetting property of the solder, the reliability of the element will not be lowered.
