Abstract: A system for reconstructing wafer maps of semiconductor wafers includes: a processor; and memory having instructions stored thereon that, when executed by the processor, cause the processor to: receive test data of a wafer at sparse sampling locations of the wafer, the sparse sampling locations being selected based on a probing mask; and compute a reconstructed wafer map by performing compressed sensing with Zernike polynomials on the test data at sparse locations of the wafer.

Abstract: Provided are a semiconductor device and a method of fabricating the same. The semiconductor device includes, a gate structure having a gate dielectric layer, a gate electrode, and a spacer, which are each formed on a substrate, a first impurity area formed in a portion of the substrate located below the spacer, a second impurity area in contact with a sidewall of the first impurity area and formed in the substrate on both sides of the gate structure, and a dielectric pattern in contact with a portion of the first impurity area and formed on a sidewall of the second impurity area. At this time, the second impurity area may include an upper part with an upward-narrowing width and a lower part with a downward-narrowing width.
