    摘要: The present invention provides a fuse of a semiconductor device and a method of forming a fuse of a semiconductor device. The method of the invention includes forming an underlying metal conductor on a semiconductor substrate, forming an insulating film over the underlying metal conductor, and selectively etching regions of the insulating film. One of the regions of the insulating film is etched to form a via contact region exposing the underlying metal conductor. A second region is etched to form a groove in the insulating film for the fuse metal. Metal is buried within the second etched region of the insulating film and the via contact region to respectively form a fuse metal pattern and a via contact metal layer. The fuse metal pattern can be formed from copper and/or tungsten.

    摘要: In a method of forming a metal gate in a semiconductor device, a gate insulation pattern and a dummy gate pattern are formed on a substrate. An insulation interlayer is formed on the dummy gate pattern to cover the dummy gate pattern. The insulation interlayer is polished such that a top surface of the dummy gate pattern is exposed, and the dummy gate pattern is selectively removed to form a trench on the substrate. A gate spacer is formed on an inner sidewall of the trench for determining a gate length of the metal gate. A metal is deposited to a sufficient thickness to fill the trench to form a metal layer. The metal layer is polished to remain in the trench. Accordingly, the gate length of the metal gate may be reduced no more than the resolution limit of the photolithography exposing system.

    摘要: In a method of manufacturing a semiconductor device, a gate insulation layer and a gate electrode are sequentially formed on a substrate on which an active region is defined. A planarized layer is formed on the substrate including the gate electrode. The planarized layer partially removed, and an upper portion of the gate electrode is exposed. A silicon epitaxial layer is selectively formed only on the exposed gate electrode, and the planarized layer is completely removed. A gate spacer is formed along side surfaces of the gate electrode and the silicon epitaxial layer. A source/drain region is formed on a surface portion of the active region corresponding to the gate electrode. Since the silicon epitaxial layer is formed only on the gate region except the source/drain region, the gate resistance is stabilized and the parasitic capacitance between the gate electrode and the source/drain region is reduce.
