Abstract: A method is provided for fabricating a transistor. The method includes providing a semiconductor substrate; and forming a trench in the semiconductor substrate by etching the semiconductor substrate. The methods also includes forming a threshold-adjusting layer doped with a certain type of threshold-adjusting ions to adjust the threshold voltage of the transistor on the semiconductor substrate in the trench; and forming a carrier drifting layer on the threshold-adjusting layer. Further the method includes forming a gate structure on the carrier drifting layer corresponding to the trench.

Abstract: Various embodiments provide transistor devices and fabrication methods. An exemplary transistor device with improved carrier mobility can be formed by first forming a confining layer on a semiconductor substrate to confine impurity ions diffused from the semiconductor substrate to the confining layer. An epitaxial silicon layer can be formed on the confining layer, followed by forming a gate structure on the epitaxial silicon layer. A portion of the epitaxial silicon layer can be used as an intrinsic channel region. A source region and a drain region can be formed in portions of each of the epitaxial silicon layer, the confining layer, and the semiconductor substrate.
