Abstract: A method for making a semiconductor device is described. That method comprises forming on a substrate a first gate dielectric layer that has a first substantially vertical component, then forming a first metal layer on the first gate dielectric layer. After forming on the substrate a second gate dielectric layer that has a second substantially vertical component, a second metal layer is formed on the second gate dielectric layer. In this method, a conductor is formed that contacts both the first metal layer and the second metal layer.

Abstract: An inter-layer dielectric structure and method of making such structure are disclosed. A composite dielectric layer, initially comprising a porous matrix and a porogen, is formed. Subsequent to other processing treatments, the porogen is decomposed and removed from at least a portion of the porous matrix, leaving voids defined by the porous matrix in areas previously occupied by the porogen. The resultant structure has a desirably low k value as a result of the porosity and materials comprising the porous matrix and porogen. The composite dielectric layer may be used in concert with other dielectric layers of varying porosity, dimensions, and material properties to provide varied mechanical and electrical performance profiles.

The maintenance of the hard mask, such as a nitride hard mask, may protect the polysilicon gate structure 14 from the formation of silicide or etch byproducts. Either the silicide or the etch byproducts or their combination may block the ensuing polysilicon etch which is needed to remove the polysilicon gate structure and to thereafter replace it with an appropriate metal gate technology.

Abstract: An electrochemical planarization apparatus for planarizing a metallized surface on a workpiece includes a platen, a conductive element disposed adjacent the platen and a polishing surface disposed adjacent the conductive element. A workpiece carrier is configured to carry a workpiece and press the workpiece against the polishing surface while causing relative motion between the workpiece and the polishing surface. A voltage source is configured to effect an electric potential difference between the metallized surface on the workpiece and the conductive element so that an electric field is produced between the metallized surface and the conductive element. The apparatus further includes a solution application mechanism configured to supply an electrolytic solution to the polishing surface.
