Method of forming a conductive line and a method of forming a conductive contact adjacent to and insulated from a conductive line

Abstract

This invention includes methods of forming conductive lines, and methods of forming conductive contacts adjacent conductive lines. In one implementation, a method of forming a conductive line includes forming a conductive line within an elongated trench within first insulative material over a semiconductive substrate. The conductive line is laterally spaced from opposing first insulative material sidewall surfaces of the trench. The conductive line includes a second conductive material received over a different first conductive material. The second conductive material is recessed relative to an elevationally outer surface of the first insulative material proximate the trench. A second insulative material different from the first insulative material is formed within the trench over a top surface of the conductive line and within laterally opposing spaces received between the first insulative material and the conductive line. In one implementation, a conductive contact is formed adjacent to and insulated from the conductive line.
