Autocorrelation and cross-correlation functions are proposed for 2D and 3D surface texture comparisons. At the maximum correlaton point of the two correlated
Features on photomasks used in the semiconductor industry have steadily decreased in size to fit more elements on a wafer. When the size becomes smaller than
Over the past decade modern measurement uncertainty evaluation has evolved from an obscure art practiced at National Measurement Institutes (NMIs) to an
Key Comparisons are international inter-laboratory studies used to establish the degree of equivalence between national measurement standards. These studies
