Capacitor with three-dimensional high surface area electrode and methods of manufacture

摘要: A capacitor, and methods of its manufacture, having improved capacitance efficiency which results from increasing the effective area an electrode surface are disclosed. An "three-dimensional" capacitor may be constructed with layers three-dimensional aspects at point interface a dielectric such that portions extend into layer. Advantageously, embodiments three- dimensional drastically reduce space footprint is required in circuit to accommodate when compared current designs. Increased density realized without using high k (high constant) materials, additional "electrode - electrode" arrangements ever stack, or serially stringing together multiple capacitors.
