    摘要: A semiconductor device includes a substrate including a first region and a second region each having an n-type region and a p-type region, wherein the n-type region in the first region includes a silicon channel, the p-type region in the first region includes a silicon germanium channel, and the n-type region and the p-type region in the second region respectively include a silicon channel. A first gate insulating pattern formed of a thermal oxide layer is disposed on the substrate of the n-type and p-type regions in the second region.

    摘要: A method of fabricating a semiconductor device includes providing a semiconductor substrate including a channel region, forming a gate electrode structure on the channel region of the semiconductor substrate, forming a first trench in the semiconductor substrate, and forming a second trench in the semiconductor device. The first trench may include a first tip that protrudes toward the channel. The second trench may be an enlargement of the first trench and may include a second tip that also protrudes toward the channel region. In some examples, the second tip may protrude further towards the channel region than the first tip.
