Abstract
A pattern can be projected on a resist film layer deposited on a semiconductor surface. The pattern can include structural elements having different feature sizes. Structural elements having feature sizes below a certain limit are not resolved on the resist film layer. The dimension of the corresponding resist pattern can be reduced and the difference can be related to focus parameters of the exposure tool.
