Description

technical field [0001] The present invention relates to the structure of a capacitor, and in particular to the structure of a capacitor of an integrated circuit. Background technique [0002] With the advancement of semiconductor technology, integrated circuits have become important components in electronic devices. Among them, the embedded capacitor in the integrated circuit is often an important component in the crystal circuit. However, to configure a capacitor with a large enough capacitance value in the integrated circuit often consumes a large layout area of ​​the integrated circuit, and therefore, under the consideration of the cost of the integrated circuit, how to construct a capacitor with a large enough capacitance in the integrated circuit The value of embedded capacitance has become a topic that designers in this field pay attention to. Contents of the invention [0003] The present invention provides a capacitor of an integrated circuit, which utilizes a li...
