Abstract

Memory structures with an embedded sheet of separated Si nanocrystals were prepared by low pressure chemical vapour deposition using a Si 3N 4 control layer and different SiO 2 or Si 3N 4 tunnel layers. It was obtained that Si nanocrystals improve the charging behaviour of the MNOS structures. Memory window width of 1.3 V and 2.0 V were obtained for pulse amplitudes of ±9 V and ±10 V, 100 ms, respectively. The extrapolated memory window after 10 years is about 15% of its initial value.
