摘要:
Methods for using and/or storing a pellicle-reticle assembly that does not result in the formation of haze on the reticle and/or the formation of wrinkles on the pellicle.
摘要:
A pellicle membrane is mounted between an outer frame and an inner frame. At least one of the frames is attached to the reticle without using conventional adhesives. The pellicle and reticle may be used in a lithography system. The pellicle allows radiation to pass through the pellicle to the reticle and may prevent particles from passing through the pellicle.
摘要:
An embodiment of the present invention includes a technique to improve stability of a pellicle. The pellicle is pre-baked at a predetermined temperature substantially below a glass transition temperature. The pre-baked pellicle is purged with an inert gas. The purged pellicle is radiated by a radiation at a wavelength. In another embodiment, a chamber is sealed with a pellicle membrane which divides the chamber into first and second compartments. The chamber has an inflow opening in the first compartment and an outflow opening in the second compartment. A gas is injected into the inflow opening and penetrates the pellicle membrane to the outflow opening. In another embodiment, the chamber has first inflow and outflow openings and second inflow and outflow openings in the first and second compartments, respectively. A first gas is injected into the first inflow opening and a second gas into the second inflow opening. The first and second gases have a permeability difference. The first gas penetrates the pellicle membrane to the second outflow opening.
摘要:
A method for simultaneously planarizing to relatively equal smoothness a thin film magnetic head hardbaked resist structure having relatively low surface energy and one or more additional thin film magnetic head structures containing other materials having comparatively higher surface energy, such as copper, hardbaked resist, alumina and NiFe. The method begins with preparation of a chemical mechanical polishing (CMP) slurry targeted at equaling the removal rate of the materials to be planarized. The CMP slurry includes a liquid vehicle, an abrasive, and a surfactant. The CMP slurry is applied to the surface of the structures to be planarized and the structures are simultaneously planarized using a CMP planarization technique.
