Abstract: A method for making a novel structure having borderless and self-aligned polysilicon and metal contact landing plugs for multilevel interconnections on integrated circuits is achieved. An etch-stop layer and a planar insulating layer are formed over the devices on a substrate. Contact openings are etched in the insulating layer to the etch-stop layer and the etch-stop layer is removed over the N.sup.- contact areas. An N.sup.+ doped polysilicon layer is deposited, and second contact openings are etched in the polysilicon and insulating layers over N.sup.+ and P.sup.+ contacts on the substrate to the etch-stop layer. The etch-stop layer is selectively removed and a conducting barrier layer and a metal layer are deposited having a second etch-stop layer on the surface. The layers are patterned to form interconnecting lines and concurrently to form polysilicon landing plugs to the N.sup.- contacts, while forming metal landing plugs to the N.sup.+ and P.sup.+ contacts.
