Abstract
A photomask used for manufacturing a semiconductor device includes a substrate; and one or more layers disposed over the substrate, the one or more layers defining a full field area and a reduced field area with a primary pattern being formed in the reduced field area, wherein the full field area is defined by a width of at least 90 mm and a length of at least 100 mm, and the reduced field area is defined by a width within the range of approximately 20-80 mm and a length within the range of approximately 20-80 mm, a center point of the primary patterned area being spaced a predetermined distance from a center point of the photomask so that the primary patterned area avoids photomask defects.
