    摘要： In a method of manufacturing a semiconductor device including independent gate patterns separated from each other, an active region is defined by forming a field region on a substrate. A gate oxide layer and a polysilicon layer are formed on the substrate. A preliminary gate pattern is formed by partially removing the polysilicon layer along a first direction by a first etching process. A spacer is formed along a side surface of the preliminary gate pattern. A number of separated gate patterns is formed by partially removing the preliminary gate pattern along a second direction crossing the first direction by a second etching process. The gate patterns overlap with the active regions and are separated from each other. Therefore, the overlap margin is increased, and the polysilicon layer is prevented from being over-etched when it is patterned to form the gate pattern.

    摘要： Provided is a method of fabricating a CMOS transistor in which, after a polysilicon layer used as a gate is formed on a semiconductor substrate, a photoresist pattern that exposes an n-MOS transistor region is formed on the polysilicon layer. An impurity is implanted in the polysilicon layer of the n-MOS transistor region using the photoresist pattern as a mask, and the photoresist pattern is removed. If the polysilicon layer of the n-MOS transistor region is damaged by the implanting of the impurity, the polysilicon layer of the n-MOS transistor region is annealed, and a p-MOS transistor gate and an n-MOS transistor gate are formed by patterning the polysilicon layer. The semiconductor substrate, the p-MOS transistor gate and the n-MOS transistor gate is cleaned with a hydrofluoric acid (HF) solution, without causing a decrease in height of the n-MOS transistor gate.

    摘要： A method of fabricating a semiconductor device using a self-aligned metal shunt process is disclosed. The method can include sequentially forming a lower conductive pattern and a sacrificial pattern on a semiconductor substrate. An interlayer dielectric layer is formed to cover the sacrificial pattern. The interlayer dielectric layer is patterned to form a preliminary trench that exposes the top surface of the sacrificial pattern. The exposed sacrificial pattern is removed to form a trench that expose the top surface of the lower conductive pattern. An upper conductive pattern is formed to fill the trench.
