Abstract
A semiconductor device including a substrate, a mesa post overlying the substrate and having a substantially cylindrical shape, a resin member surrounding the mesa post and a stress moderating member received in the mesa post for moderating stress between the mesa post and the resin member. The stress applied to the mesa post is reduced because the entire volume of the resin member is divided by the stress moderating member and each of the divided resin members reduces the stress.
Claims4
A surface emitting semiconductor laser device comprising a substrate and a layer structure formed thereon, the layer structure including a mesa post which comprises multi-layer film reflector and which is surrounded by a resin member having a stress moderating for moderating stress between the mesa post and the resin member.
