Patent ID: 8643142

Claim:
A passive device, comprising: a stack formed on a substrate, the stack comprising alternating layers of a conductive material and a dielectric material, the stack is formed in a peripheral region of the substrate, lateral of a 3D stacked non-volatile memory cell array on the substrate, and the alternating layers of the conductive material and the dielectric material comprise at least a first set of the alternating layers, and a second set of the alternating layers above or below the first set of the alternating layers and arranged vertically with the first set of the alternating layers, the first set of the alternating layers is part of a first passive device and the second set of the alternating layers is part of a second passive device; a first set of contact structures associated with the first set of the alternating layers; and a second set of contact structures associated with the second set of the alternating layers, the layers of conductive material in the first set of the alternating layers are connected to one another in parallel or serially by the first set of contact structures and the at least one upper metal layer, and the layers of conductive material in the second set of the alternating layers are connected to one another in parallel or serially by the second set of contact structures and the at least one upper metal layer, separate from the first set of the alternating layers, wherein: the first set of the alternating layers are connected to one another in parallel; and the layers of conductive material in the first set of the alternating layers are plates of a capacitor as the first passive device; the second set of the alternating layers are connected to one another serially; and the layers of conductive material in the second set of the alternating layers are resistive components of a resistor as the second passive device.
