    摘要: A photomask and a method for forming an opaque border on the same are disclosed. In an example method of manufacturing a photomask, no more than one patterning operation is used to form a mask field with an opaque border substantially surrounding the mask field. The border region may be substantially covered by an opaque material, and features in the mask field may be free from the opaque material. When the photomask is used to expose a pattern on an object, the opaque border may substantially prevent electromagnetic radiation (EMR) from exposing portions of the object outside the field of exposure associated with the mask field. The operation of forming the mask field may include forming an insulating clear region surrounding the features and leaving the border region outside the insulating clear region. The opaque layer may be deposited by electroplating or spraying an opaque material onto the border region.

    摘要: A photomask assembly and method for protecting the photomask assembly from contaminants generated during a lithography process are disclosed. A photomask assembly includes a pellicle assembly formed from a pellicle frame and a pellicle film coupled to a first surface of the pellicle frame. The pellicle frame further includes an inner wall and an outer wall. A photomask is coupled to a second surface of the pellicle frame opposite the pellicle film. A molecular sieve that prevents airborne molecular contaminants (AMCs) generated during a lithography process from contaminating the photomask is associated with the pellicle assembly.
