Abstract

The invention discloses a high-energy-storage electronic capacitor. The high-energy-storage electronic capacitor comprises a first power supply unit, a second power supply unit, and at least two large-capacity capacitors which are connected in series between the first power supply unit and the second power supply unit; the large-capacity capacitors which are stacked capacitors are distributed above an MOS capacitor on a base plate, and each stacked capacitor comprises a lower electrode conductive layer, a dielectric layer and an upper electrode conductive layer which are sequentially stacked. According to the high-energy-storage electronic capacitor, the large-capacity capacitors can be synchronously formed in a peripheral circuit area while forming the unit capacitor with the stacked structure, namely, the large-capacity capacitor can be formed in the peripheral circuit area without a metal joint, and the large-capacity capacitors can be arranged above the MOS capacitor.

Description

technical field [0001] The invention relates to the field of capacitors, in particular to an electronic capacitor with high energy storage. Background technique [0002] As we all know, the basic function of a capacitor is charging and discharging, but many circuit phenomena extended from this basic charging and discharging function make capacitors have various uses. For example, in electric motors, we use it to generate phase shift; in In photographic flashlights, it is used to generate high-energy instantaneous discharges, etc.; and in electronic circuits, capacitors with different properties are used in particular. Although these many different uses are quite different, they all come from charging with discharge. [0003] Nowadays, due to the limitations of physical and chemical characteristics, even the high-performance batteries developed at the most advanced technical level have great limitations and deficiencies in discharge power and continuous charge a...
