Abstract:
A method for fabricating a microelectronic component, the method which comprises:forming a storage capacitor on a substrate by providing a first electrode and a second electrode and by providing a dielectric selected from the group consisting of a ferroelectric dielectric and a paraelectric dielectric disposed between the first electrode and the second electrode; forming a barrier by producing a silicon oxide layer on the storage capacitor, by subjecting the storage capacitor and at least part of the silicon oxide layer to a heat treatment, and by applying a barrier layer on the silicon oxide layer for protecting against a passage of hydrogen through the barrier; and forming the barrier layer from a plurality of partial layers each protecting against the passage of hydrogen, including: applying a first one of the partial layers; subsequently applying a silicon nitride layer as a second one of the partial layers; and depositing the silicon nitride layer with a low pressure microwave process and activating at least one silicon nitride precursor with microwave radiation during the low pressure microwave process.
