Abstract
PURPOSE: To obtain a glass sealed diode which has good reverse direction characteristics by covering with an Ag-Cu solder prior to an etching of an assembly, and then immersing in an etching agent.
CONSTITUTION: A Cu reed 11 and a Mo electrode 13 are combined by means of Ag-Cu solder 12, then covered with a glass slurry 21 and the slurry is fired. A pellet 22 is fixed by means of a high temperature treatment to the electrode reed covered with the glass, and this assembly is etched in an acid for obtaining a required reverse direction withstand voltage. Then the pellet is covered with a glass slurry and it is fired. By so doing, the solder is not etched when the assembly is etched because the Ag-Cu solder is covered. Thus Ag or Cu is prevented from adhering on the pellet. This increases reverse direction withstand voltage. In addition, the Ag-Cu solder enables to obtain a glass sealed diode that has good antimoisture characteristics and adhesiveness between a reed and an electrode.
