Abstract: PURPOSE:To form a pattern of extremely narrow width of high alignment precision for an alignment pattern by a method wherein an alignment pattern formed on a substrate is irradiated with charged particle beam in a material gas atmosphere, and generated secondary electron or reflected electron is detected, thereby performing alignment. CONSTITUTION:In a material gas atmosphere, an alignment pattern 2 formed on a substrate 1 is irradiated with charged particle beam 3.
