Abstract:
1. A pellicle for lithography comprising a frame, a membrane, and an agglutinant layer for attaching the pellicle frame to an exposure original plate, wherein the said agglutinant layer has a Young's modulus of 0.01 to 0.10 MPa, a tensile bond strength of 0.02 to 0.10 N/mm 2 , and a surface flatness of 0 to 15 micrometers and wherein said agglutinant layer is provided such that when an adhesion-assist load of 0.008 to 5 kgf, including the weight of the pellicle, is applied for the pellicle to adhere to the exposure original plate, no air pass is created.
