Original Abstract Submitted
An optoelectronic semiconductor device includes a substrate, a first type semiconductor structure located on the substrate, a second type semiconductor structure located on the first type semiconductor structure, an active structure located between the first type semiconductor structure and the second type semiconductor structure, a plurality of contact portions disposed between the first type semiconductor structure and the substrate, and a first conductive oxide layer, a second conductive oxide layer, a first insulating layer and a second insulating layer. The plurality of contact portions is separated from each other, and one of them includes a semiconductor and has a side wall. The first conductive oxide layer contacts the contact portion, and the second conductive oxide layer contacts the first conductive oxide layer. The first insulating layer contacts the side wall. The second insulating layer is disposed between the first insulating layer and the second conductive oxide layer.
