Abstract: Methods and systems are described for generating assessment maps. A method includes receiving a first vector map comprising a first set of vectors each indicating a distortion of a particular location on a substrate and generating a second vector map indicating a change in direction of a magnitude of the distortion of the particular location on the substrate. The method further includes generating a third vector map comprising vectors reflecting reduced noise in distortions across the plurality of locations on the substrate and generating a fourth vector map projecting a direction component of each vector component in the third set of vectors to a radial direction. The method further includes generating a fifth vector map by grouping the vectors of the fourth set of vectors and determining a magnitude associated with each group of vectors.

Abstract: Methods, systems, and non-transitory computer readable medium are described for generating assessment maps for corrective action. A method includes receiving a first vector map including a first set of vectors each indicating a distortion of a particular location of a plurality of locations on a substrate. The method further includes generating a second vector map including a second set of vectors by rotating a position of each vector in the first set of vectors. The method further includes generating a third vector map including a third set of vectors based on vectors in the second set of vectors and corresponding vectors in the first set of vectors. The method further includes generating a fourth vector map by subtracting each vector of the third set of vectors from a corresponding vector in the first set of vectors. The fourth vector map indicates a planar component of the first vector map.

Abstract: Exemplary methods of forming semiconductor structures may include forming a silicon oxide layer from a silicon-containing precursor and an oxygen-containing precursor. The methods may include forming a silicon nitride layer from a silicon-containing precursor, a nitrogen-containing precursor, and an oxygen-containing precursor. The silicon nitride layer may be characterized by an oxygen concentration greater than or about 5 at. %. The methods may also include repeating the forming a silicon oxide layer and the forming a silicon nitride layer to produce a stack of alternating layers of silicon oxide and silicon nitride.
