A semiconductor device includes: a package including: a heat dissipating body comprising a metal, an insulting part surrounding the heat dissipating body, one or more semiconductor laser elements disposed on the heat dissipating body, at least one outer metal layer that is located on a lower surface of the insulting part and is spaced from a lower surface of the heat dissipating body; a mounting substrate including: at least one first metal pattern located at an upper surface of the mounting substrate, and a second metal pattern located at the upper surface of the mounting substrate; at least one first bonding member located between the at least one outer metal layer and the first metal pattern; and a second bonding member located between the lower surface of the heat dissipating body and the second metal pattern, wherein the second bonding member comprises a metal material.

Semiconductor device and method of manufacturing the semiconductor device

A semiconductor device includes: a package including: a lower surface, at least one first metal surface at an outer periphery of the lower surface, and at least one second metal surface at the lower surface at a location different from the at least one first metal surface; a mounting substrate disposed below the package and including: an upper surface, at least one first metal pattern disposed at the upper surface below the at least one first metal surface, and at least one second metal pattern disposed at the upper surface below the at least one second metal surface; a first bonding member containing a metal material and bonding the at least one first metal surface and the at least one first metal pattern; and a second bonding member containing a metal material and bonding the at least one second metal surface and the at least one second metal pattern.

A method of manufacturing a semiconductor device includes: providing a package; providing a mounting substrate; providing at least one first bonding member disposed at a position connecting at least one first metal surface of the package and at least one first metal pattern of the mounting substrate; providing a second bonding member connecting at least one second metal surface of the package and at least one second metal pattern of the mounting substrate; and heating the at least one first bonding member and the at least one second bonding member at a temperature equal to or higher than both a bonding temperature of the at least one first bonding member and a bonding temperature of the at least one second bonding member, to bond the package and the mounting substrate together.
