The present disclosure relates to a polishing pad, a method for manufacturing the polishing pad, and a method for manufacturing a semiconductor device using the polishing pad. The polishing pad increases the area in direct contact with the semiconductor substrate during the polishing process and can prevent defects occurring on the surface of the semiconductor substrate by forming a plurality of uniform pores in the polishing layer, thereby adjusting the surface roughness characteristics of the polishing surface of the polishing layer. Further, the present disclosure may provide a method for manufacturing a semiconductor device to which the polishing pad is applied.

The present invention relates to a method of making a foamed cellulosic fiber-thermoplastic composite article. The method includes the steps of providing a copolymer composition, combining the copolymer composition and cellulosic fibers, applying heat, mixing energy and pressure to form a foamable mixture, and forming the foamable article in a molding or extruding operation. The method is characterized in that at least 10% of the cellulosic fibers have been thermally modified prior to being combined with the copolymer composition.

A foaming resin composition of the present invention contains an aromatic vinyl-based resin and zinc oxide, wherein the size ratio (B/A), in which peak A is a 370 nm to 390 nm region and peak B is a 450 nm to 600 nm region, of zinc oxide is approximately 0.01 to approximately 1 when photoluminescence is measured, and the BET surface area thereof is approximately 1 m.sup.2/g to approximately 10 m.sup.2/g.

An assembly for molding a composite article including a foam core and a layer is disclosed. The assembly includes a mold. The mold has an inner surface and at least partially defines a cavity, one or more gas discharge ports, and one or more retaining elements. Each of the one or more gas discharge ports has a passageway opening in fluid communication with the cavity of the mold the mold. The assembly further includes one or more sealing elements moveably engaged with the mold. Each of the one or more sealing elements includes a head and is shaped to engage the retaining element on the mold in a vented position. Further, each of the one or more sealing elements corresponds with each of the one or more gas discharge ports.

This invention concerns a process for producing particle foam part in which foam particles are heated in a molding tool so that they weld to the particle foam part. Heat is supplied to the foam particles by means of electromagnetic RF radiation. The foam particles are made of polyurethane (PU), polylactate (PLA), polyethylene block amide (PEBA) or polyethylene terephthalate (PET).

A method of making a foamed article, for example a foamed component for an article or footwear, comprises forming a structure of interconnected, unfoamed, thermoplastic polymeric members spaced to define openings between the thermoplastic polymeric members. The structure may be made by printing a thermoplastic polymeric material with a three-dimensional printer. The thermoplastic polymeric members are heated to a first temperature to soften the thermoplastic polymeric members and the softened thermoplastic polymeric members are infused with at least one inert gas at a first pressure greater than atmospheric pressure. The first pressure is sufficient to cause the at least one inert gas to permeate into the softened thermoplastic polymeric members. After being infused with the inert gas, the pressure is reduced to at least partially foam the thermoplastic polymeric members.

Provided are a method for manufacturing a molded foam, and a molded foam. A method for manufacturing a molded foam includes: a molding step of molding the molded foam; and a releasing step of opening a fixed mold and a mobile mold and extruding the molded foam from the fixed mold by an ejector pin. The molded foam has an inclined face that is inclined relative to a direction of opening the mold. The inclined face has a recess for extruding of the molded foam by the ejector pin. The tip surface of the ejector pin has a first extruding surface that is perpendicular to the mold opening direction and forms a bottom face of the recess, and a second extruding surface that is inclined relative to the first extruding surface.
