Abstract:
A method for fabricating a pellicle assembly for a lithography process includes fabricating a pellicle frame including a sidewall having a porous material. In some embodiments, the pellicle frame is subjected to an anodization process to form the porous material. The porous material includes a plurality of pore channels extending, in a direction perpendicular to an exterior surface of the sidewall, from the exterior surface to an interior surface of the sidewall. In various embodiments, a pellicle membrane is formed, and the pellicle membrane is attached to the pellicle frame such that the pellicle membrane is suspended by the pellicle frame. Some embodiments disclosed herein further provide a system including a membrane and a pellicle frame that secures the membrane across the pellicle frame. In some examples, a portion of the pellicle frame includes a porous material, where the porous material includes the plurality of pore channels.
