An electrical connector with thin interior walls is made by extruding a polymer or polymer composite into a sheet of approximately 0.25 mm to 0.5 mm thickness. The sheet is then calendered to a thickness of about 0.05 mm to 0.3 mm. The calendered sheet is cut into notched sections. The notched sections are assembled and placed into an injection molded housing of a connector. The sections are secured in place by using an adhesive, force fit, snap fit, or welding process to form the thin interior walls of the connector.

A photomask assembly is described having a frame for supporting a transparent pellicle above a photomask substrate, defining a closed pellicle space overlaying the substrate. The frame is formed of a porous material configured to allow the pellicle space to be purged with an inert gas within a reasonable processing time period, thereby removing any harmful chemicals that might be present. The frame preferably is made by a method that includes preparing a gel by a sol-gel process, drying the gel, and partially densifying the dry gel. The resulting frame has a gas permeability to oxygen or nitrogen higher than about 10 ml.mm/cm.min.MPa, an average pore size between 0.001 micrometer and 10 micrometers, and a coefficient of thermal expansion between 0.01 ppm/&#xb0; C. and 10 ppm/&#xb0; C.
