Abstract:
1. An optoelectronical semiconductor device having a bonding structure, comprising: a first optoelectronical structure comprising a first p-n or p-i-n junction; a second optoetectronical structure comprising a second p-n or p-i-n junction; and a transparent bonding structure formed in-between the first optoetectronical structure and the second optoelectronical structure to connect therewith electrically; wherein the transparent bonding structure comprises a first conductive layer comprising a first bonding surface, a second conductive layer comprising a second bonding surface, and a transparent adhesive layer connecting the first conductive layer and the second conductive layer and sandwiched therebetween, and at least one of the first bonding surface and the second bonding surface is an uneven surface, and parts of the first bonding surface are directly in contact with that of the second bonding surface; wherein the transparent adhesive layer does not directly contact the first optoelectronical structure and the second optoelectronical structure; wherein the first conductive layer and/or the second conductive layer comprise a transparent metal oxide layer or a thin metal layer; and wherein the transparent metal oxide layer comprises at least one material selected from the group consisting of indium tin oxide, cadmium tin oxide, antimony tin oxide, zinc tin oxide, and ZnO.
