It is shown that the damage produced by the plasma during deposition of the SiNx coating can be reduced by decreasing the SiNx:H deposition temperature for a thin SiNx:H layer of ~30 nm. Furthermore, the optical analysis shows that the blistering of the Al2O3/SiNx:H stacks after SiNx:H deposition depends on the deposition temperature and the thickness of the SiNx:H layer in the case of a direct PECVD. Moreover, the density of blisters seems to be decreased by increasing the Al2O3 deposition temperature. An annealing step of 370°C for 40 min under atomic hydrogen atmosphere or under nitrogen atmosphere after SiNx:H deposition seems to be beneficial for the samples not showing severe blister formation (Al2O3/SiNx:H stack with a SiNx:H layer deposited by direct PECVD at 300°C or by indirect PECVD at 400°C). deposit-license 2013
