Abstract
Integrated circuits and methods for manufacturing the same are provided. An integrated circuit includes a base dielectric layer, a first dielectric layer overlying the base dielectric layer, and a second dielectric layer overlying the first dielectric layer. A first overlay mark is positioned within the first dielectric layer, and a second overlay mark is positioned within the second dielectric layer, where the second overlay mark is offset from the first overlay mark. First and second blocks are positioned within the base dielectric layer, where the first overlay mark directly overlays the first block and the second overlay mark directly overlays the second block.
