    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: 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.

    摘要: A semiconductor device includes a gate insulator and a gate electrode stacked on a substrate, a source/drain pattern which fills a recess region formed at opposite sides adjacent to the gate electrode, the source/drain pattern being made of silicon-germanium doped with dopants and a metal germanosilicide layer disposed on the source/drain pattern. The metal germanosilicide layer is electrically connected to the source/drain pattern. Moreover, a proportion of germanium amount to the sum of the germanium amount and silicon amount in the metal germanosilicide layer is lower than that of germanium amount to the sum of the germanium amount and silicon amount in the source/drain pattern.
