Abstract
Methods and structures for reducing resistance in wordlines of an integrated circuit memory device are disclosed. In one embodiment, the method includes forming multiple columns of polycrystalline silicon for respective number of wordlines, forming core transistor junctions and periphery transistor junctions associated with the wordlines, performing a salicidation process for the periphery transistor junction and performing a salicidation process for the columns of polycrystalline silicon to from the wordlines with low resistance.
