Abstract: A method of manufacturing a semiconductor device comprises providing a semiconductor substrate, forming trenches in predetermined regions of the semiconductor substrate, forming isolation structures within the trenches that separate active regions and field regions of the device, and etching exposed regions of the semiconductor substrate so that the exposed regions of possess a curved surface. In a specific embodiment of the invention, an oxidization process is performed to compensate for damage on the exposed regions of the semiconductor substrate after etching the semiconductor substrate, and a wet etch process is performed to remove an oxide layer grown by the oxidization process. In a specific embodiment of the invention, the etch process may comprise a wet or dry etch process.

Abstract: A joint sealing structure for waterproof sheets for a cool roof includes a first waterproof sheet and a second waterproof sheet installed in such a manner that their edges are spaced apart from each other with a predetermined gap in-between and a polymer-filled portion that fills the gap. The polymer-filled portion is formed by filling the gap with a liquid polymer that has fire-retardant property. The waterproof sheet includes a waterproof sheet layer and a top reinforce layer placed on one side of the waterproof layer. The top reinforce layer is impregnated in the liquid polymer and then dried, and is treated to have a light color. The top reinforce layer is a fiberglass cloth having a plurality of glass fibers woven with one another. The polymer is impregnated onto the fiberglass cloth in such a thickness so that there are no glass fibers exposed out of the polymer.

Abstract: A finger nail is decorated with an image printed on a piece of glossy coated paper, such as from a magazine, by applying a film-forming substance over the image to the piece, the substance including a resin and a solvent that is capable upon drying of forming a film that is sufficiently flexible and extensible to permit it to conform to the surface of the nail. After allowing the substance to dry and form the film, the paper under the film is wetted with water and the paper is removed to leave a film/image/paper-coating sandwich that is substantially free of paper fibers. The sandwich is cut to form a blank of a size and shape to fit the margins of the cuticle bordering the finger nail. The sized and shaped blank is applied to the finger nail, and a settable nail top coat substance in liquid form is applied over the blank and allowed to dry.
