Abstract
A method for electrically quantifying a semiconductor device's spacers' width. In one embodiment, a method comprises the step of measuring a resistance across a region of interest of each of a plurality of semiconductor structures including the semiconductor device in question, where the region of interest may be a source or drain region of the semiconductor structure or may be one of a plurality of lightly doped drain regions of the semiconductor structure. The method further comprises determining a width of one of a plurality of lightly doped drain regions of the semiconductor device from the resistance across the region of interest of each of the plurality of semiconductor structures. The method further comprises determining the semiconductor device's spacers' width from the width of one of the plurality of lightly doped drain regions of the semiconductor device.
