摘要:
A memory cell structure includes a substrate having a bottom electrode at least partially disposed within the substrate; a pad disposed at least partially over the substrate; a phase change element having a chalcogenide material, disposed at least partially over the substrate and adjacent to the pad, the phase change element being adjacent and operatively coupled to the bottom electrode; and a top electrode operatively coupled to the phase change element. Moreover, the pad is formed by a method including depositing a first material layer over the substrate, etching the first material layer to form a pad strip and to expose the bottom electrode, and etching the pad strip to from the pad.
