Abstract: A mask for etching a target layer includes a mask substrate. A phase inversion layer is disposed to correspond to a non-etched area of a pattern target layer. The phase inversion layer is configured to generate inverted light by inverting a phase of incident light and to transmit the inverted light to the non-etched area of a pattern target layer. An inversion offset part is disposed in a center part of the phase inversion layer. The inversion offset part is configured to generate offset light causing destructive interference with the inverted light in the non-etched area and to provide the offset light to the non-etched area.
