Capacitor

A capacitor, comprising:

• a) a bottom conductive structure;
• b) at least one middle conductive structure, each middle conductive structure having a first conductive pattern and a second conductive pattern surrounding an outer side of the first conductive pattern, wherein the first conductive pattern and the second conductive pattern of each layer of the middle conductive structure form an interdigitated structure;
• c) a top conductive structure, comprising a third conductive pattern and a fourth conductive pattern arranged at an outer side of the third conductive pattern, wherein the third conductive pattern and the fourth conductive pattern form an interdigitated structure;
• and
• d) wherein the bottom conductive structure, at least one middle conductive structure, and the top conductive structure are sequentially stacked along a first direction, adjacent conductive structures at least partially overlap in the stacking direction, all of the first conductive patterns and the third conductive patterns are electrically connected to each other as a first capacitive pole, and the bottom conductive structure, all of the second conductive patterns and the fourth conductive pattern are electrically connected to each other as a second capacitive pole.
