Abstract
The present invention relates to a transistor and the method for forming the same. The transistor of the present invention comprises a semiconductor substrate; a gate dielectric layer formed on the semiconductor substrate; a gate formed on the gate dielectric layer; and a source region and a drain region located in the semiconductor substrate and on respective sides of the gate, wherein only the source region comprises at least one dislocation. The method for forming a transistor according to the present invention comprises forming a mask layer on a semiconductor substrate on which a gate has been formed so that the mask layer covers the gate and the semiconductor substrate; patterning the mask layer to only expose at least a portion of a source region; performing a first ion implantation to the exposed portion of the source region; and annealing the semiconductor substrate so as to form a dislocation in the exposed portion of the source region.
