A method of manufacturing a semiconductor device includes forming a first protective layer over an edge portion of a first main surface of a semiconductor substrate. A metal-containing photoresist layer is formed over the first main surface of the semiconductor substrate. The first protective layer is removed, and the metal-containing photoresist layer is selectively exposed to actinic radiation. A second protective layer is formed over the edge portion of the first main surface of the semiconductor substrate. The selectively exposed photoresist layer is developed to form a patterned photoresist layer, and the second protective layer is removed.

Photoresist developer and method of developing photoresist

Coated nanotubes and bundles of nanotubes are formed into membranes useful in optical assemblies in EUV photolithography systems. These optical assemblies are useful in methods for patterning materials on a semiconductor substrate. Such methods involve generating, in a UV lithography system, UV radiation. The UV radiation is passed through a coating layer of the optical assembly, e.g., a pellicle assembly. The UV radiation that has passed through the coating layer is passed through a matrix of individual nanotubes or matrix of nanotube bundles. UV radiation that passes through the matrix of individual nanotubes or matrix of nanotube bundles is reflected from a mask and received at a semiconductor substrate.

A pellicle assembly includes a pellicle membrane with a nanotube layer formed from thick nanotube bundles. The pellicle membrane can be formed with multiple layers and has a combination of long lifetime, high transmittance, low deflection, and small pore size. A conformal coating may applied to an outer surface of the pellicle membrane. The conformal coating protects the pellicle membrane from damage that can occur due to heat and hydrogen plasma created during EUV exposure.

The present disclosure provides a method for repairing a seam within a conformally deposited material. One or more seam repairing precursor sources may be delivered to seams or voids using a carrier at a super critical fluid phase. At the super critical fluid phase, the carrier has liquid like density and gas like high diffusion capability, therefore capable of delivering the repairing precursor sources to seams or voids under surfaces of a structure. In some embodiments, carbon dioxide or argon may be used as a carrier.
