  • Publication number: 20200171799
    Abstract: Described herein are articles and methods of making articles, for example glass articles, comprising a thin sheet and a carrier, wherein the thin sheet and carrier are bonded together using a modification (coating) layer, for example a cationic polymer coating layer, and associated deposition methods, the carrier, or both, to control van der Waals, hydrogen and covalent bonding between the thin sheet and the carrier. The modification layer bonds the thin sheet and carrier together with sufficient bond strength to prevent delamination of the thin sheet and the carrier during high temperature (?600° C.) processing while also preventing formation of a permanent bond between the sheets during such processing.

  • Patent number: 6620708
    Abstract: A semiconductor device and method for fabricating a semiconductor device yields improved doping efficiency and increased capacitance. The method includes forming a silicon film on a substrate. HSG having a spherical projection forms on a surface of the silicon film. The surface of the silicon film having the HSG is washed, and a lower electrode forms by a doping process. A dielectric film and an upper electrode are sequentially formed on the silicon film without washing.

  • Patent number: 6413787
    Abstract: A method for fabricating a dielectric film can increase capacitance by etching a film generated by annealing for preprocess using NO gas. The method for fabricating the dielectric film includes: a step for performing a first annealing on a silicon lower electrode, and forming a first insulating film on the upper surface of the silicon lower electrode; a step for etching the first insulating film; a step for forming a second insulating film on the silicon lower electrode; and a step for performing a second annealing.
