Patent ID: 7670914

Claim:
A method for fabricating a multiple finger transistor, the method comprising the steps of: forming at least two gate electrodes overlying a surface of a semiconductor substrate, wherein the at least two gate electrodes are separated by a space; implanting first impurity dopants into the semiconductor substrate using a first implant energy, wherein the at least two gate electrodes serve as an implantation mask; forming first sidewall spacers about the at least two gate electrodes and within the space, wherein the first sidewall spacers within the space contact each other; implanting second impurity dopants into the semiconductor substrate using a second implant energy, wherein the first sidewall spacers and the at least two gate electrodes serve as an implantation mask; removing a portion of the semiconductor substrate from the surface of the semiconductor substrate to form a recess; selectively epitaxially growing semiconductor material in the recess on the semiconductor substrate; removing the first sidewall spacers; and forming regions comprising metal on the semiconductor material.
