  • Patent number: 11996468
    Abstract: A method of fabricating a device includes providing a fin having an epitaxial layer stack with a plurality of semiconductor channel layers interposed by a plurality of dummy layers. In some embodiments, the method further includes exposing lateral surfaces of the plurality of semiconductor channel layers and the plurality of dummy layers within a source/drain region of the semiconductor device. In some examples, the method further includes etching the exposed lateral surfaces of the plurality of dummy layers to form recesses and forming an inner spacer within each of the recesses, where the inner spacer includes a sidewall profile having a convex shape. In some cases, and after forming the inner spacer, the method further includes performing a sheet trim process to tune the sidewall profile of the inner spacer such that the convex shape of the sidewall profile becomes a substantially vertical sidewall surface after the sheet trim process.

  • Publication number: 20240170225
    Abstract: This invention describes a packaging structure for roll-type (wound-type) aluminum conductive polymer capacitor element. Two protective substrates are applied to sandwich a roll-type capacitor element in between with an insulating material surrounding the capacitor element also in between the protective substrates. The protective substrates comprise electrically separated anodic conductive pad and cathodic conductive pad on their surfaces and through holes that pass through the conductive pads. The capacitor element is oriented with its axis perpendicular to the two substrates. The anodic and cathodic leads of the capacitor element pass through the through holes. An anodic external terminal is plated over the anodic conductive pad and a cathodic external terminal is plated over the cathodic conductive pad so that the anodic external terminal is electrically connected to the anodic lead and the cathodic external terminal is electrically connected to the cathodic lead.
