Semiconductor Devices Including Elevated Source and Drain Regions
摘要：
Methods of fabricating semiconductor devices are provided. A substrate having active patterns and isolating layer patterns is prepared. Each of the isolating layer patterns has an upper surface higher than that of each of the active patterns. A spacer layer having a uniform thickness is formed on the substrate. The spacer layer is etched to form a spacer on a sidewall of each of the isolating layer patterns. A gate structure is formed on each of the active patterns. A selective epitaxial growth (SEG) process is performed on the active patterns having the gate structure to form isolated epitaxial layers that have upper surfaces higher than those of the isolating layer patterns, on the active patterns. Related semiconductor devices are also provided.

提供制造半导体器件的方法。 制备具有活性图案和隔离层图案的基板。 每个隔离层图案的上表面高于每个活动图案的上表面。 在基板上形成具有均匀厚度的间隔层。 蚀刻间隔层以在每个隔离层图案的侧壁上形成间隔物。 在每个有源图案上形成栅极结构。 对具有栅极结构的有源图案进行选择性外延生长（SEG）处理，以在活性图案上形成具有高于绝缘层图案的上表面的隔离的外延层。 还提供了相关的半导体器件。
