Abstract:
1. A method of manufacturing a plurality of spacers in a film stack, comprising: forming at least one electrically-conductive element having sidewalls on a substrate; depositing an etch stop layer at one side of the substrate; depositing a plurality of passivation layers at the one side of the substrate, the plurality of passivation layers including a spacer passivation layer and an electrical isolator passivation layer; and performing etching of the spacer passivation layer to form a plurality of spacers substantially across from the sidewalls of the at least one electrically-conductive element, the etch stop layer interposed between the at least one electrically-conductive element and the plurality of spacers, and in contact with the plurality of spacers and the electrical isolator passivation layer, the etch stop layer and the electrical isolator passivation layer coextensively extended along the one side of the substrate.
