Abstract:
PURPOSE: The semiconductor memory device reduces the misalign generation between the contact. The resistivity fault between the contact, and the short failure and the not-open fault are prevented. CONSTITUTION: A word line having the first effective pitch(P1) is located on surface unit active areas. The bit line having the first effective pitch is located on surface word lines. The first pad contact(210) is arranged between word lines. The direct contact(212) each other electrically connects first pad contacts and bit line. The second pad contact(214) is arranged between word lines and bit lines.
Abstract:
A manufacturing method of a semiconductor device including an isolation process is provided to reduce a depth of an isolation pattern by applying a bias to a conductive pattern included in the isolation pattern. A plurality of isolation patterns including conductive patterns(14a) are formed on an upper surface of a semiconductor substrate(10). A gap(19) is formed between the isolation patterns. An active pattern(20) is formed on the semiconductor substrate in order to bury the gap formed between the isolation patterns. A gate insulating layer(22) is formed on an upper surface of the isolation pattern and an upper surface of the active pattern. A gate pattern(24) is formed on an upper surface of the gate insulating layer.
Abstract:
A contact structure of a semiconductor device and a method for forming the same are provided to increase a margin of a photolithography process by maximizing a contact area. A first interlayer dielectric is formed on a semiconductor substrate. A bit line structure(32) is formed across bit lines on the first interlayer dielectric in order to contact an active region through a direct contact plug. A second interlayer dielectric is formed on the substrate including the bit line structure. A barrier pattern(37) is formed in parallel to the bit line structure on the substrate including the second interlayer dielectric. A mask pattern(40) is extended perpendicularly to the bit line structure across the upper part of the direct contact plug on the substrate including the barrier pattern. A buried contact hole(42h) is formed by etching the second and first interlayer dielectrics. The buried contact hole is filled with a buried contact plug.
Abstract:
A semiconductor integrated circuit devices having a gate pattern suitable for physically spacing electrical nodes from each other on a semiconductor substrate with the gate pattern disposed between the electrical nodes and methods for forming the same are provided to improve electrical characteristics by easily arranging gate patterns at a cell array region and a circuit region, and the electric nodes around the gate patterns. A semiconductor substrate(5) has an active region(16). Gate patterns(49,64) have gates(38,59) and gate capping patterns(46,62). The gate patterns are arranged on the semiconductor substrate. The gates are located under an upper surface of the active region and extended toward the semiconductor substrate. The gate capping patterns are located on the gates and protruded from the upper surface of the active region. A lower dielectric(34) and an upper dielectric(23) are respectively arranged under the upper surface of the active region and on the upper surface of the active region to surround the gate pattern. An upper surface of the upper dielectric is located at a lower level than that of an upper surface of the gate capping pattern.
