A method of forming an electrically conductive plug includes providing an
opening within electrically insulative material over a node location on a
substrate. An electrically conductive material is formed within the
opening and elevationally over the insulative material. Some of the
conductive material is removed effective to recess an outermost surface
of the conductive material to from about 100 Angstroms to about 200
Angstroms from an outermost surface of the insulative material after said
removing of some of the conductive material. After removing some of the
conductive material, remaining volume of the opening over the conductive
material is overfilled with an electrically conductive metal material
different from that of the conductive material. The metal material is
polished effective to form an electrically conductive plug within the
opening comprising the conductive material and the metal material. Other
aspects and implementations are contemplated.
