  • Publication number: 20240102170
    Abstract: The present invention provides a high-crystallinity barium titanate film structure, a method of preparation and an application thereof, and relates to the field of materials and devices. The method includes the steps of depositing, on a substrate, a barium titanate layer with a (001) or (111) crystal orientation by atomic layer deposition in a high vacuum environment and at a low temperature of 450° C. or below, wherein a Ba/Ti ratio in the barium titanate layer is 0.9-1.5; and performing plasma annealing treatment on the barium titanate layer at a low temperature of 450° C. or below without breaking vacuum to form a high-crystallinity barium titanate layer having the (001) or (111) crystal orientation. The film structure may further comprise top and bottom electrodes formed above and below the barium titanate layer. The present invention solves the problem that an existing method for obtaining a crystalline BTO film is not applicable to back-end of line (BEOL) integration processes.

  • Patent number: 11296301
    Abstract: The present disclosure relates to display screens and manufacturing methods of display screens. The display screen includes a packaged component, a non-display area including an effective package area adjacent to the packaged component, and a package shadow area located at a periphery of the effective package area. The package shadow area includes a supporting substrate defining a groove for disconnecting a thin film package structure formed on the support substrate. The thin film package structure is disconnected at the groove.
