摘要:
A thin-film encapsulation for an optoelectronic semiconductor body includes a PVD layer deposited by a PVD method, and a CVD layer deposited by a CVD method, wherein the CVD layer is applied directly on the PVD layer, and the CVD layer is etched back such that the CVD layer only fills weak points in the PVD layer.
