Abstract:
In an embodiment a method for producing optoelectronic semiconductor devices includes providing at least one optoelectronic semiconductor chip with at least one contact side, generating at least one coating region and at least one protection region on the contact side or on at least one of the contact sides, applying at least one liquid coating material to the at least one contact side, wherein the at least one coating material wets the at least one coating region and does not wet the at least one protection region and solidifying the at least one coating material into at least one electrical contact structure on the at least one coating region such that the semiconductor chip is capable of being energized through the at least one contact structure.
