    摘要: Methods of fabricating semiconductor integrated circuit devices are provided. A substrate is provided with gate patterns formed on first and second regions. Spaces between gate patterns on the first region are narrower than spaces between gate patterns on the second region. Source/drain trenches are formed in the substrate on opposite sides of the gate patterns on the first and second regions. A first silicon-germanium (SiGe) epitaxial layer is formed that partially fills the source/drain trenches using a first silicon source gas. A second SiGe epitaxial layer is formed directly on the first SiGe epitaxial layer to further fill the source/drain trenches using a second silicon source gas that is different from the first silicon source gas.

    摘要: The present invention relates to a phase changeable structure having decreased amounts of defects and a method of forming the phase changeable structure. A stacked composite is first formed by (i) forming a phase changeable layer including a chalcogenide is formed on a lower electrode, (ii) forming an etch stop layer having a first etch rate with respect to a first etching material including chlorine on the phase changeable layer, and (iii) forming a conductive layer having a second etch rate with respect to the first etching material on the etch stop layer. The conductive layer of the stacked composite is then etched using the first etching material to form an upper electrode. The etch stop layer and the phase changeable layer are then etched using a second etching material that is substantially flee of chlorine to form an etch stop pattern and a phase changeable pattern, respectively.

    摘要: In a method of manufacturing a semiconductor device, a first gate electrode and a second gate electrode are formed in a first area and a second area of a substrate. Non-crystalline regions are formed in the first area of the substrate adjacent the first gate electrode. A layer having a first stress is formed on the substrate and the first and the second gate electrodes. A mask is formed on a first portion of the layer in the first area of the substrate to expose a second portion of the layer in the second area. The second portion is etched to form a sacrificial spacer on a sidewall of the second gate electrode. The second area of the substrate is partially etched using the mask, the second gate electrode and the sacrificial spacer, to form recesses in the second area of the substrate adjacent the second gate electrode. Patterns having a second stress are formed in the recesses.
