Abstract

A pellicle assembly includes a pellicle membrane and a conformal coating on an outer surface of the pellicle membrane. The pellicle membrane can be formed with multiple layers and has a combination of high transmittance, low deflection, and small pore size. The conformal coating is intended to protect the pellicle membrane from damage that can occur due to heat and hydrogen plasma created during EUV exposure.
