Abstract
(DE)

Die Erfindung betrifft ein Verfahren zur Herstellung eines optoelektronischen Bauelements, bei dem ein Leiterrahmen (10) mit zumindest einem ersten Abschnitt und einem davon beabstandeten zweiten Abschnitt mit jeweils wenigstens 2 Auflagebereich (14) bereitgestellt wird, wobei der Auflagebereich (14) jeweils zumindest teilweise von einer Vertiefung (11) umgeben sind. Ein lichtemittierender Halbleiterkörpers (20r, 20b, 20g) wird auf den Auflagebereich (14) eines jeden Abschnitts aufgebracht und die Abschnitte zur Bildung einer Vielzahl von Chipgruppen (1), insbesondere Chipgruppen gleicher Bauweise getrennt. Anschließend wird ein Träger (3) bereitgestellt, der eine Vielzahl voneinander beabstandete Bereiche aufweist, die jeweils Kontaktelemente (33) umfassen. Die Chipgruppe wird in oder auf jeweils einen der Vielzahl voneinander beabstandeten Bereiche des Trägers aufgebracht und kontaktiert. Dann werden die Bereiche vereinzelt. embedded image
