    摘要: An upper insulating layer is formed on a semiconductor substrate, the upper insulating layer having an etch selection ratio relative to a lower insulating layer. The upper insulating layer is anisotropically etched by using a contact pad forming mask, to form an opening exposing an upper surface of the semiconductor substrate between conductive patterns on the substrate. The side walls of the upper insulating layer are then isotropically etched, using the above mask again, to expand the size of the opening. The expanded opening is then filled with a conductive layer to form a contact pad to be electrically connected to the semiconductor substrate.

    摘要: A method of forming a semiconductor memory device using a double layered capping pattern and a semiconductor memory device formed thereby are provided. A plurality of interconnection patterns are formed on a semiconductor substrate. Each of the interconnection patterns includes a interconnection line and a double layered capping pattern. The double layered capping pattern includes a first capping pattern and a second capping pattern, which are sequentially stacked. The second capping pattern is formed of a material layer having an etching selectivity with respect to the first capping pattern. A planarized separating layer is formed between the adjacent interconnection patterns. The substrate having the planarized separating layer is covered with a sacrificial layer. The sacrificial layer is formed of a material layer having a wet etching selectivity with respect to the planarized separating layer. The sacrificial layer and the planarized separating layer are patterned to form a hole exposing a predetermined region of the semiconductor substrate. The hole is filled with a conductive pattern. The sacrificial layer is then removed to thereby protrude the conductive pattern. The conductive pattern and the second capping pattern are planarized, thereby forming a conductive plug in the hole and concurrently exposing the first capping pattern.
