    摘要: A semiconductor device for determining an overlay error on a semiconductor substrate includes a first and a second transistor. Each transistor includes two diffusion regions associated with a gate, the diffusion regions of each transistor being arranged in a first direction. The second transistor is arranged adjacent to the first transistor in a second direction perpendicular to the first direction. The first and second gate each have a non-uniform shape, and the second gate is oriented with respect to an orientation of the first gate in such a way that an effect of an overlay error on a device parameter of the second transistor has an opposite sign in comparison to an effect of the overlay error on the device parameter of the first transistor.

    摘要: A method according to one embodiment of the invention may be applied to enhance scatterometry measurements made from a two-component test pattern. Reference patterns corresponding to each of the components of the two-component pattern are also printed. Scatterometry signals derived from the reference patterns, corresponding to the separate components of the test pattern, are used to enhance the signal from the test pattern to improve sensitivity and signal-to-noise ratios.
