Abstract:
A method of producing a contact element for an optoelectronic component includes providing an auxiliary carrier with a sacrificial layer arranged on a top side of the auxiliary carrier; providing a carrier structure having a top side and a rear side situated opposite the top side, wherein an insulation layer is arranged at the rear side of the carrier structure; connecting the sacrificial layer to the insulation layer by an electrically conductive connection layer; creating at least one blind hole extending from the top side of the carrier structure as far as the insulation layer; opening the insulation layer in a region of the at least one blind hole; arranging an electrically conductive material in the at least one blind hole; detaching the auxiliary carrier by separating the sacrificial layer; and patterning the electrically conductive connection layer.
