Abstract

A method for producing a plurality of optoelectronic semiconductor devices is provided. A number of semiconductor chips are fastened on an auxiliary support. The semiconductor chips are spaced apart from one another in a lateral direction. A reflective layer is formed, at least in regions between the semiconductor chips. A composite package body is formed at least in certain regions between the semiconductor chips. The auxiliary support is removed and the composite housing body is separated into a number of optoelectronic semiconductor devices. Each optoelectronic semiconductor device has at least one semiconductor chip, part of the reflective layer and part of the composite package body as a package body.
