Abstract:
A gate electrode is formed on an active region. An embedded stressor which fills a trench formed in the active layer is arranged. The active region has a sigma shape (∑-shape) which is formed by the trench. The embedded stressor includes a lower semiconductor layer and the upper semiconductor layer of the lower semiconductor layer. The upper end of the upper semiconductor layer protrudes from the upper end of the active region to be higher than the active region. The upper semiconductor layer is narrower than the lower semiconductor layer. The lateral surface of the upper semiconductor layer is dislocated from the lateral surface of the lower semiconductor layer.
Abstract:
A method of manufacturing a semiconductor device is provided. A gate electrode is formed on a substrate. A first spacer, a second spacer, a third spacer are successively formed on the sidewall of the gate electrode. A recess region is formed by etching the substrate. A compressive stress pattern is formed in the recess region. A protection spacer is formed on the sidewall of the third spacer. When the recess region is formed, the lower part of the second spacer is removed to form a gap region between the first spacer and the third spacer. The protection spacer fills the gap region.

Abstract:
A method for a zirconium carbon oxynitride insulation film, a semiconductor device using the same, and a manufacturing method thereof are provided to increase capacity of a device per unit area by excluding an electrode film of a wide dimension. A bottom electrode(180) is formed on a semiconductor substrate(100). A zirconium organic nitrogen source is absorbed on the bottom electrode. A non-reactive source is removed from the zirconium organic nitrogen. A zirconium carbon oxynitride layer is formed by supplying an oxidizer gas to the zirconium organic nitrogen absorption layer. The non-reactive oxidizer is removed. A nitriding agent is supplied to the zirconium carbon oxynitride layer. A top electrode(195) is formed on the zirconium carbon oxynitride layer.
