发明名称 Overhanging separator for self-defining stacked capacitor
摘要 An overhanging separator structure with a post projecting from a surface which may be a substrate, an underlying layer on the surface, and a separator layer on the underlying layer, with the separator layer overhanging the underlying layer. A discontinuous film is then formed in a single process step having a first portion on the separator layer and a second portion on the post, the discontinuity caused by the overhanging separator layer. The structure is made into a stacked capacitor with the second (post) portion of the discontinuous film being the bottom electrode, by forming a continuous dielectric layer on the bottom electrode and a continuous top electrode layer on the dielectric layer.
