Abstract: The force, by which the glass sheets of a laminated glass push onto each other, is applied to the edges of the laminated glass to prevent the delamination of the laminated glass caused by moisture penetrating or diffusing from these edges into the intermediate film. A pair of glass sheets having different curvatures, in which if the pair of glass sheets are laid on each other, aligning their edges, their central portions are apart from each other and do not adhere to each other, and in which if bent, their surfaces adhere to each other, are bonded with a PVB film, while being bent so that their surfaces adhere to each other to form a laminated glass. At the edges of the laminated glass, in the portion where the glass sheets try to regain their original shapes to push onto each other through the intermediate film, the delamination of the glass sheets is inhibited.

Abstract: In a method for manufacturing an integrated circuit arrangement, trenches that define active zones are formed in a substrate. A first insulating layer that fills the narrow trenches is conformally deposited and is structured with a mask and anisotropic etching such that spacers arise at sidewalls of the wide trenches and supporting locations arise in a region of the wide trenches. The surface of the active zones is uncovered by forming a second insulating layer with an essentially planar surface and by a planarizing layer erosion on the basis of chemical-mechanical polishing or conventional dry etching.
