Method of measuring alignment of measurement pattern
Abstract:
A resist pattern for alignment measurement being shrunk by a heat flow includes a plurality of positive type or negative type line patterns. Widths of spaces between the line patterns are greater than twice those of the line patterns. Alternatively, the resist pattern comprises a box-shaped or slit-shaped measurement pattern and a pair of box-shaped or slit-shaped auxiliary patterns provided inside and outside the measurement pattern, respectively.
