Claim 15:
16. The method according to claim 15, wherein the mixed AlPxOy-film formed by applying a number of POx-layers and a number of Al-containing layers, wherein the ratio between the atomic percentage of phosphorus and phosphorus+aluminium aluminum (P/(P+Al)) in the POx- and Al-comprising-layer is tailored to obtain an optimal balance between the effective excess carrier lifetime τeff (s), the fixed charge density Qf(cm−2) and the interface state density DA (eV−1 cm−2), and
wherein the tailoring is effected by applying a desired number of POx-layers and a desired number of Al-comprising layers for forming the mixed AlPxOy-film.
