TL;DR: In this paper, a solid electrolytic capacitor using a conducting polymer to be formed by chemical oxidative polymerization is described, the capacitor having a capacitor element which includes a polymer layer with a thickness of 0.02 μm or greater at its central part.
Abstract: A solid electrolytic capacitor using a conducting polymer to be formed by chemical oxidative polymerization as a solid electrolyte, the capacitor having: a capacitor element which includes a conducting polymer layer with a thickness of 0.02 μm or greater at its central part. A method for making the solid electrolytic capacitor, having the steps of: providing at least two kinds of solutions with different oxidizing-agent concentrations; and adjusting the thickness of a conducting polymer layer at central part of a capacitor element to be 0.02 μm or greater by using first a solution with a lowest oxidizing-agent concentration of the solutions and subsequently a solution with a next lowest oxidizing-agent concentration of the solutions.

TL;DR: In this paper, various stages in the production of an aluminium electrolytic capacitor are outlined and these are then related to the equivalent circuit so as to establish an understanding of the preparation parameters that affect the performance.
Abstract: The various stages in the production of an aluminium electrolytic capacitor are outlined and these are then related to the equivalent circuit so as to establish an understanding of the preparation parameters that affect the performance. Particular reference is made to studies undertaken on the effects of etching prior to anodization, the anodization itself, the electrolyte used and the mechanical construction. In the case of sintered porous tantalum electrolytic capacitors, the parameters are not so well understood but comparisons will be drawn with aluminium capacitors wherever possible.

TL;DR: A failure mechanism is analyzed by conducting a load-life test on high-output cylindrical-shaped electrochemical capacitors under different voltages and temperatures and found that a 180% increase in the dc ESR over its initial level is the most appropriate factor to be used as a failure condition for electrochemical capacitor performance.

TL;DR: In this paper, a high capacitance embedded capacitor and associated fabrication processes are disclosed for fabricating a capacitor stack in a multi-layer stack to include a first capacitor plate conductor formed with a cylinder-shaped storage node electrode formed in the multilayer stack.
Abstract: A high capacitance embedded capacitor and associated fabrication processes are disclosed for fabricating a capacitor stack in a multi-layer stack to include a first capacitor plate conductor formed with a cylinder-shaped storage node electrode formed in the multi-layer stack, a capacitor dielectric layer surrounding the cylinder-shaped storage node electrode, and a second capacitor plate conductor formed from a conductive layer in the multi-layer stack that is sandwiched between a bottom and top dielectric layer, where the cylinder-shaped storage node electrode is surrounded by and extends through the conductive layer.
