  • Publication number: 20090155567
    Abstract: The extruded propylene-based resin foam according to the present invention is extruded propylene-based resin foam that is formed by extrusion-foaming a propylene-based resin, and the extruded propylene-based resin foam has the expansion ratio of 10 or more and the average cell diameter of less than 400 ?m. In addition, the extruded foam contains a 60 or less wt % fibrous filler in relation to the whole molding material. With this configuration, the extruded foam can have a plurality of foam cell walls therein. Thus, the extruded foam can efficiently block external radiant heat, thereby realizing excellent insulation efficiency. Furthermore, because the fibrous filler is oriented along the thickness direction, even when the extruded foam is slightly strained in the thickness direction, a high stress arises, thereby improving energy-absorbing capability.

    Abstract: A method is provided for determining a process window for a lithography process using a reflective mask. The method begins by selecting a target Critical Dimension (CD) of a feature in an image pattern to be formed on a wafer and a corresponding CD tolerance. A CD of the feature formed on the wafer is determined as a function of exposure and focus position of light used in the lithography process. A shift in position of the image pattern is determined as a function of the exposure and the focus position. For the selected target CD and the selected corresponding CD tolerance, an Exposure-Defocus-Shift of pattern position (EDS).
