    摘要: End of line effect can occur during manufacture of components using a lithographic apparatus. These end of line effects can result in line end shortening of the features being manufactured. Such line end shortening may have an adverse impact on the component being manufactured. It is therefore desirable to predict and/or monitor the line end shortening. A test pattern is provided that has two separate areas such that, as designed, when the two areas are illuminated with radiation (for example from an angle-resolved scatterometer) they result in diffused radiation with asymmetry that is equal in sign to each other, but opposite in magnitude. When the test pattern is actually manufactured, line end shortening occurs, and so the asymmetry of the two areas are not equal and opposite. From the measured asymmetry of the manufactured test pattern, the amount of line end shortening that has occurred can be estimated.
