CERAMIC PACKAGE AND MANUFACTURING METHOD THEREFOR

摘要

In a ceramic package, a seal ring is brazed to a substrate portion. A joint portion of the seal ring includes: a metallization layer; a first plating layer disposed on the metallization layer; and a brazing material layer disposed on the metallization layer with the first plating layer interposed therebetween. An end of the brazing material layer is located outside a region directly below the seal ring and at a position at the seal ring side away from an end of the metallization layer by 0.02 mm or greater.

主权项

1. A ceramic package comprising:
a ceramic substrate having a surface; a metallization layer disposed along an outer periphery of a predetermined region on the surface of the ceramic substrate; a first plating layer disposed on the metallization layer; a brazing material layer disposed on the metallization layer with the first plating layer interposed therebetween; and a seal member joined on the metallization layer via the brazing material layer, wherein at least one of an outer peripheral portion and an inner peripheral portion of the brazing material layer, an end of the brazing material layer is located outside a region directly below the seal member and the end of the brazing material layer is positioned at least 0.02 mm nearer to the seal member than an end of the metallization layer.
