摘要:
A semiconductor device includes a substrate including first and second regions, a first transistor provided on the first region to include a first channel region protruding from the substrate, and a second transistor provided on the second region to include a second channel region and a gate electrode extending between the substrate and the second channel region. The first channel region may include a lower semiconductor pattern containing a different material from the second channel region and an upper semiconductor pattern containing the same material as the second channel region.
摘要:
A semiconductor device includes a substrate, an insulating layer disposed on the substrate and having a trench exposing a surface portion of the substrate, and a channel-forming structure comprising crystalline semiconductor material. The channel-forming structure has a lower portion located in the trench and fins extending upright on the lower portion, where the fins are spaced from each other and are each narrower than an opening of the trench, and the lower portion of the channel forming structure has a higher crystal defect density than the fins of the channel forming structure.
