Circuit using dielectric unit capacitor

Abstract

This invention relates to a circuit using a thin dielectric unit condenser including one or more than one circuit modules and one or more than one decoupling modules coupled to said circuit modules, in which, every decoupling module has one or more decoupling thin dielectric unit condensers including: a first node coupled to a first circuit connecting point of the circuit module, a second node coupled to a second circuit connecting point of the circuit module and two or more thin dielectric condensers connected between the two nodes in series and at least the thickness of a grid dielectric of a thin dielectric condenser is less than 50.

Description

technical field [0001] The present invention relates to a capacitor for an integrated circuit, and more particularly to an integrated circuit having a stacking thin dielectric decoupling capacitor with high unit capacitance. Background technique [0002] In a general semiconductor chip structure, logic gates in an integrated circuit (hereinafter referred to as IC) are coupled to power lines and ground lines. When the power supply provides power to the IC, the current will flow through the power line, logic components, and flow to the ground line. When logic elements switch, the current changes dramatically over a small period of time. The decoupling capacitor can be used to withstand the interference caused by the above-mentioned current change, and maintain the voltage between the power supply and the ground at a constant value. A good decoupling capacitor has low leakage current, short time constant, and high capacitance per unit area. It is generally known that the dec...
