Provided is a semiconductor device manufacturing method that includes joining a support substrate to a back side of a semiconductor wafer across a ceramic adhesive layer and a mask, to form a joined body. The method further includes forming a functional structure on a front side of the semiconductor wafer. The method further includes detaching the support substrate from the semiconductor wafer by removing the ceramic adhesive layer and the mask. The method further includes a back side processing step of carrying out back side processing on the back side of the semiconductor wafer.

A face skin for an acoustic panel may comprise a sheet defining a first surface and a second surface. A plurality of slots may be formed through the face skin using abrasive blasting. Each slot of the plurality of slots may comprise a first semi-circular wall and a second semi-circular wall opposite the first semi-circular wall.

A multilayer medical packaging film includes a first layer and a chlorine dioxide-producing layer. The chlorine dioxide-producing layer includes a polymer composition and a plurality of chlorite ions. The chlorine dioxide-producing layer is substantially free of an energy-activated catalyst and is substantially free of an acid-releasing compound. However, the film is capable of generating chlorine dioxide when exposed to UV light and moisture.

A method of manufacturing a flexible display panel includes forming an adhesive layer by depositing an inorganic material on a flexible substrate, forming a hydroxyl group on a surface of the adhesive layer by modifying the surface of the adhesive layer, laminating a glass substrate to the modified surface of the adhesive layer and forming a heat-treated layer by heating the glass substrate and the adhesive layer.

A method for bonding components of an electrostatic chuck includes applying a first melting point depressing layer (MDL) to a bottom surface of a first puck plate including one or more functional elements of an electrostatic chuck. A second MDL is applied to a top surface of a second puck plate including one or more functional elements of the electrostatic chuck, and a metal interlayer is provided between the first MDL and the second MDL. The first puck plate, the metal interlayer, and the second puck plate are aligned to form a puck assembly, and the puck assembly is heated, to a temperature at or near the eutectic temperature of the first MDL or the second MDL, to thermally bond the first puck plate to the metal interlayer and the metal interlayer to the second puck plate.

Disclosed are gypsum slurries, gypsum boards, and methods of preparing gypsum board using a high-efficiency lignosulfonate dispersant. The high-efficiency lignosulfonate surprisingly and unexpectedly allows for enhancing the fluidity of the gypsum slurry without requiring the presence of dispersants that are biologically detrimental (including to human and environmental health), or are prepared using harmful materials such as aldehydes (e.g., formaldehyde). In embodiments, the presence of the high-efficiency lignosulfonate allows for excluding a synthetic dispersant such as polynapthalene sulfonate (PNS) or melamine sulfonate.
