Abstract
An optoelectronic device includes, in a stack, an emitting layer having optically active structures, configured to emit or receive radiation, a sensitive layer having at least one structure having a temperature resistance below a temperature Tmax below 200° C., a bond layer, and a transparent support layer. The bond layer is based on an inorganic low temperature bonding material. The bond layer also has cavities directly in line with the optically active structures, between the transparent support layer and the sensitive layer.
