    摘要: A method of fabricating a contact plug of a semiconductor device is provided, the method includes forming a gate pattern on a substrate, forming a capping pattern to cover an upper surface and sidewalls of the gate pattern, forming an interlayer insulation layer on the substrate such that the interlayer insulation layer exposes an upper surface of the capping pattern, and removing a portion of the capping pattern and the interlayer insulation layer such that the upper surface of the capping pattern is planarized.

    摘要: Disclosed is a slurry and method for chemical-mechanical polishing operation. The slurry may contain abrasive particles, an oxidizer, a pH controller, a chelating agent and water. The viscosity of the slurry may be in the range of about 1.0 cP—about 1.05 cP, so that the step difference may be reduced between regions with patterns and without patterns even after completing the chemical-mechanical polishing operation. A permissible rate of depth of focus (DOF) may not need to be controlled in the subsequent photolithography operation, which may enable the subsequent photolithography operation to be conducted by an optical system with relatively low DOF.

    摘要: A test pattern and a method of controlling a CMP using the same are provided. The test pattern is disposed on a monitoring region of a semiconductor substrate having a main region and a monitoring region. The test pattern includes a planar region and a pattern region. The method comprises setting a correlation between a step difference of a test pattern and an etched thickness of a main pattern, then applying the CMP to a semiconductor substrate having the test pattern and the main pattern for a predetermined time. The step difference of the test pattern is measured and the etched thickness of the main pattern, which corresponds to the step difference of the test pattern, is determined from the correlation. A polishing time is corrected by comparing the determined etched thickness of the main pattern with a reference value, and the corrected polishing time is applied to a subsequent lot or subsequent substrate.
