A pellicle assembly for large-size photomasks including a frame member configured to be affixed to a large-size photomask substrate, a substantially rigid and transparent pellicle membrane affixed to the frame member so as to protect at least a portion of the large-size photomask substrate from contamination during usage, storage and/or transport, and a coating on at least one of top and bottom surfaces of the pellicle membrane that binds the pellicle membrane to prevent separation of pellicle membrane material in the event of breakage.

Pellicle for flat panel display photomask

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.

Photomask having a reduced field size and method of using the same

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.
