Claim 0:
1. A semiconductor device comprising:
a package comprising:
a heat dissipating body comprising a metal,
an insulating part surrounding the heat dissipating body,
one or more semiconductor laser elements disposed on the heat dissipating body, and
first and second outer metal layers that are located on a lower surface of the insulating part and are spaced from a lower surface of the heat dissipating body,
wherein the lower surface of the heat dissipating body has a rectangular shape, the first outer metal layer is located at a first side of the rectangular shape, and the second outer metal layer is located at a second side of the rectangular shape that is opposite the first side;

a mounting substrate comprising:
first and second outer metal patterns located at an upper surface of the mounting substrate, and
an inner metal pattern located at the upper surface of the mounting substrate,
wherein the inner metal pattern is located inward of the first and second outer metal patterns and is spaced from the first and second outer metal patterns, and
wherein an area of the inner metal pattern is greater than an area of each of the first and second outer metal patterns;

a first outer bonding member located between the first outer metal layer and the first outer metal pattern, wherein the first outer bonding member comprises a metal material;
a second outer bonding member located between the second outer metal layer and the second outer metal pattern, wherein the second outer bonding member comprises a metal material; and
an inner bonding member located between the lower surface of the heat dissipating body and the inner metal pattern, wherein the inner bonding member comprises a metal material.
