    摘要: In a method for filling a hole with a metal, an insulating layer, a first mask layer and a second mask layer are successively formed on a semiconductor substrate. The first and second mask layers are etched using a photoresist pattern to form first and second masks. The first mask layer pattern is selectively etched using an etchant, the first mask layer pattern having a higher etching selectivity than the second layer pattern with respect to the etchant, to form a third mask layer pattern having a broadened opening. The insulating layer is etched using the second mask to form a hole in the insulating layer. A metal layer is formed in the hole and the third opening. The metal layer is planarized to form a metal plug buried in the hole without recesses or voids.

    摘要: A contact structure includes a lower conductive pattern disposed on a predetermined region of a semiconductor substrate. The lower conductive layer has a concave region at a predetermined region of a top surface thereof. An embedding conductive layer fills the concave region. The top surface of the embedding conductive layer is placed at least as high as the height of the flat top surface of the lower conductive pattern. A mold layer is disposed to cover the semiconductor substrate, the lower conductive pattern and the embedding conductive layer. An upper conductive pattern is arranged in an intaglio pattern. The intaglio pattern is disposed in the mold layer to expose a predetermined region of the embedding conductive layer.

    摘要: There is provided a chemical mechanical polishing apparatus, which may include a polishing table rotated by a polishing table motor and having a pad thereon, a carrier head located above the polishing table to be rotatable by the driving of a carrier head motor and having a wafer located under the bottom thereof, a slurry supplier for supplying a slurry to the upper portion of the polishing table, a first polishing end point detector for detecting a polishing end point through the temperature change of the temperature sensor, at least one temperature sensor for detecting the temperature of a polishing region (the wafer, the pad, and the slurry), and a second polishing end point detector for detecting a polishing end point from the changes of load current, voltage, and resistance of the carrier head motor. Further, instead of the second polishing end point detector, an optical signal polishing end point detector may be employed, for detecting the polishing end point by the light illuminated on the wafer and reflected from the wafer.

    摘要: A method for use in manufacturing a semiconductor device includes forming a photoresist pattern on a substrate, performing first etching process in which an initial trench is formed using the photoresist pattern as a mask, and performing second distinct etching process to enlarge the initial trench. Thus, the initial trench can be formed using the photoresist pattern having a stable structure. Thereafter, the trench is enlarged using an etching solution having a composition based on the material in which the initial trench is formed, e.g., silicon substrate or an insulation film. Therefore, a metal wiring, an isolation film or a contact can be formed in the enlarged trench to desired dimensions.

    摘要: A cleaning apparatus includes upper and lower nozzle assemblies supplying a cleaning liquid to edge and bottom sections of a semiconductor substrate. The upper nozzle assembly has a first nozzle supplying the cleaning liquid onto the edge section, and second and third nozzles supplying a nitrogen gas for preventing the cleaning liquid from moving into a center portion of the semiconductor substrate. The cleaning liquid supplied to the edge section flows from the edge section towards a side section of the semiconductor substrate due to the rotation of the semiconductor substrate. An ultrasonic wave generator is provided above the edge section for generating ultrasonic waves. The ultrasonic waves are applied to the cleaning liquid supplied onto the edge and bottom sections, thereby improving the cleaning efficiency. The cleaning apparatus has a guide to guide the cleaning liquid supplied to the edge section toward the side section. The cleaning apparatus may effectively remove impurities from the edge, side and bottom sections of the semiconductor substrate.
