A thin film capacitor includes: a metal foil having a roughened upper surface; a dielectric film covering the upper surface of the metal foil and having an opening through which the metal foil is partly exposed; a first electrode layer contacting the metal foil through the opening; and a second electrode layer contacting the dielectric film without contacting the metal foil. An angle ?a formed by the other main surface of the metal foil and a side surface thereof is more than 20° and less than 80°. The side surface is thus tapered at an angle of more than 20° and less than 80°, so that it is possible to suppress warpage and to enhance adhesion with respect to a multilayer substrate when the thin film capacitor is embedded in the multilayer substrate.

Abstract: To provide a thin film capacitor in which warpage is less likely to occur. A thin film capacitor includes: a metal foil having roughened upper and lower surfaces; a dielectric film covering the upper surface of the metal foil and having an opening through which the metal foil is partly exposed; a dielectric film covering the lower surface of the metal foil and made of a dielectric material having a thermal expansion coefficient smaller than that of the metal foil; a first electrode layer contacting the metal foil through the opening; and a second electrode layer contacting the first dielectric film without contacting the metal foil. The lower surface of the metal foil is thus covered with the dielectric film having a small thermal expansion coefficient, thereby making it possible to prevent the occurrence of warpage.

Abstract: To provide a thin film capacitor having high adhesion performance with respect to a multilayer substrate. A thin film capacitor includes: a metal foil having a roughened upper surface; a dielectric film covering the upper surface of the metal foil and having an opening through which the metal foil is partly exposed; a first electrode layer contacting the metal foil through the opening; and a second electrode layer contacting the dielectric film without contacting the metal foil. A height of the first electrode layer is lower than a height of the second electrode layer. This enhances adhesion performance when the thin film capacitor is embedded in a multilayer substrate and improves ESR characteristics.

Abstract: Nerve stimulation via a Low Frequency Alternating Current (LFAC) waveform can result in blocking of action potential conduction, while an increase in LFAC frequency and/or amplitude can translate into nerve activation. As LFAC for nerve blocking is frequency independent, the threshold LFAC activation can decrease with increasing frequency. Thus, frequency and amplitude settings can determine whether LFAC activates or blocks nerve fibers. LFAC can also be orderly, wherein smaller, non-fatiguing nerve fibers can be activated before larger nerve fibers. LFAC settings for activation can also be influenced by the configuration of a cuff assembly that positions an electrode along a nerve. The cuff can position a nerve in a cuff through hole, and a sliding closure of the cuff can be slide into a radial opening to substantially lock the nerve in the cuff assembly. An electrode material is positioned within a window of the cuff and is connected to an electrical lead.

Abstract: To prevent interfacial peeling due to the stress of an insulating layer in a capacitor-inductor integrated electronic component having three or more conductor layers. An electronic component includes: a conductor layer M1 including a conductor pattern constituting an inductor; a conductor pattern overlapping a part of the conductor pattern through a dielectric film; an insulating layer covering the conductor layer M1 and conductor pattern; a conductor layer M2 provided on the insulating layer and including a conductor pattern constituting the inductor; and an insulating layer covering the conductor layer M2. The conductor layer M2 is formed to be branching from or independently of the conductor pattern and further includes a dummy pattern overlapping the conductor pattern. This prevents the stress of the insulating layer from being directly applied to the conductor pattern to thereby prevent peeling at the interface between the conductor layer M1 and the dielectric film.

A height of the electrode layer is equal to or higher than a height of the insulating member. This makes the outer peripheral portion of the thin film capacitor have a step-like shape.
