Abstract

An optical semiconductor apparatus can be configured by mounting an optical semiconductor element on a package substrate using a solder paste. The optical semiconductor apparatus can include a package substrate and a metal die pad formed on the substrate, and an optical semiconductor element bonded to the die pad with a solder material. The substrate can be made of a ceramic base material. A plurality of through holes can be formed in the substrate so that the through holes penetrate both the substrate base material and the die pad. Each of the through holes can have an inner surface where the ceramic base material is exposed. Each through hole can have an opening diameter greater than or equal to 40 [mu]m and less than or equal to 100 [mu]m. The plurality of through holes can be formed such that the total area of the openings of the through holes is 50% or less of the bonded area between the optical semiconductor element and the die pad including the through holes covered with the solder material. The through holes can be covered with the solder material at the upper end thereof where the optical semiconductor element and the die pad are bonded to each other.

Description
