Semiconductor Manufacturing International | Date: 2015-01-28

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.

A method for forming a semiconductor device includes forming a conductive structure of a silicon material on a substrate and forming a planarized dielectric layer adjacent the conductive structure. The method also includes removing a portion of the dielectric layer to expose a top portion of the conductive structure and removing an outer portion of the exposed top portion of the conductive structure such that the top portion of the gate structure has a narrower width than the unexposed portion. The method further includes forming a metal layer over the exposed portion of the gate structure and a top surface of the dielectric layer, and forming a silicide layer over the top portion of the conductive structure. The width of the silicided top portion of the conductive structure is substantially the same as the width of the bottom portion of the conductive structure.
