Alternately, a DC-sputtering process deposits each amorphous silicon layer, and following the forming of the superlattice, polysilicon is formed by annealing the amorphous silicon layers. Silicon dioxide can be formed by either thermal annealing or by deposition using a DC-sputtering process.

    摘要: A dry etch process is described for selectively etching silicon nitride from conductive oxide material for use in a semiconductor fabrication process. Adding an oxidant in the etch gas mixture could increase the etch rate for the silicon nitride while reducing the etch rate for the conductive oxide, resulting in improving etch selectivity. The disclosed selective etch process is well suited for ferroelectric memory device fabrication using conductive oxide/ferroelectric interface having silicon nitride as the encapsulated material for the ferroelectric.
