thin-film capacitor

thin-film capacitor

[′thin ¦film kə′pas·əd·ər]
(electricity)
A capacitor that can be constructed by evaporation of conductor and dielectric films in sequence on a substrate; silicon monoxide is generally used as the dielectric.

With its greater control, ALD is attractive for the production of microelectronic devices, such as integrated circuits, ferroelectric memories, switches, radiation detectors, thin-film capacitors, microelectromechanical structures (MEMS), and--potentially--new high-k gate dielectrics that could replace silica in future generations of metal oxide semiconductor field effect transistors.
Because the complexity and variety of mechanism for dielectric breakdown, especially in films, the working voltage [V.sub.R] and the associated field strength, [E.sub.R] for thin-film capacitors are some fraction of the bulk breakdown values, that is:
Ferroelectric-epoxy-based polymer nanocomposites have the potential to surpass conventional composites and produce thin-film capacitors over large surface areas, with high-capacitance density and low loss.
They focus the evaluation on ATP's research programs on wavelength references for optical fiber communications, injectable composite bone grafts, Internet commerce for manufacturing, and polymer composite dielectrics for integrated thin-film capacitors. They conclude the volume with observations about alternative templates for public-sector program evaluation.
The Accu-P [R] series thin-film capacitors now include a high performance RF/microwave capacitor in a 0402 size.
COC can replace polypropylene (PP) in thin-film capacitors. With a 11[degrees]C (20[degrees]F) higher than the melting point of PP, COC works better than PP in high-temperature capacitors.
COCs can replace polycarbonate and polypropylene in thin-film capacitors. The new resins offer Tg's up to 20 [degrees] F higher than the melting point of PP.
Thin-film capacitors fabricated from 40% to 60% v/v BaTiO3 epoxy nanocomposites showed a stable capacitance density in the range of 5 nF/in to 20 nF/[in..sup.2] and low loss ~0.012 to 0.022.
The alumina substrate is polished to a less than 2 microinch finish to reduce RF path resistance and to improve the surface quality for high yield thin-film capacitors. The substrate thickness was chosen as a compromise between via hole inductance and microstrip geometries.
