  • Publication number: 20210341969
    Abstract: A curved display integrates in a portable information handling system housing to present visual images to an end user about an arc for improved viewing angle. The portable information handling system rotates the housing from an open position that exposes the display in a curved configuration to a closed position that brings the display against a main housing portion with the display transitioned from the curved to a planar configuration for a low profile storage position. Display curve is managed with a curved support frame that bends to a planar form, a pair of perpendicular-axis hinges that rotate opposing housings about a horizontal axis and manage display curve about a vertical axis, and a dual axis hinge with a sliding bracket that adjusts for greater housing spacing in the curved configuration.

  • Publication number: 20210288009
    Abstract: A method of forming an integrated circuit structure includes forming a patterned passivation layer over a metal pad, with a top surface of the metal pad revealed through a first opening in the patterned passivation layer, and applying a polymer layer over the patterned passivation layer. The polymer layer is substantially free from N-Methyl-2-pyrrolidone (NMP), and comprises aliphatic amide as a solvent. The method further includes performing a light-exposure process on the polymer layer, performing a development process on the polymer layer to form a second opening in the polymer layer, wherein the top surface of the metal pad is revealed to the second opening, baking the polymer, and forming a conductive region having a via portion extending into the second opening.
