Abstract
A process is provided for making a conductive structure for a semiconductor circuit, such as a one device dynamic random access memory cell, which includes the steps of depositing a conductive layer on a surface of a semiconductor substrate having a given type conductivity spaced from a storage node, depositing a layer of polysilicon over the conductive layer, depositing a layer of photoresist over the polysilicon layer, defining an opening in the photoresist layer and implanting ions of a conductivity type opposite to that of the given type conductivity through the opening and the polysilicon layer into the semiconductor substrate to form therein a conductive pocket or region having the opposite type conductivity resulting in, e.g., a highly conductive bit/sense line of a memory cell.
