Abstract

The invention discloses a circuit board which is provided with an embedded capacitor and a resistance structure, comprising a first dielectric layer, a first line layer, a second dielectric layer and a second line layer, a capacitance material layer and a lower electrode embedded in the first dielectric layer, a first resistance material layer and a first guide hole which are sequentially piled; the lower electrode is arranged at one side of the capacitance material layer; the first upper electrode and the second upper electrode of the first line layer are arranged at the other side of the capacitance material layer corresponding to the lower electrode; furthermore, the lower electrode is connected with the first upper electrode or the second upper electrode; the first connection pad of the second line layer passes through the first guide hole of the second dielectric layer and is connected with the first resistance material layer which coves at least part of the first upper electrode.

Description

technical field [0001] The present invention relates to a circuit board, and in particular to a circuit board with embedded capacitance and resistance structures. Background technique [0002] With the development of science and technology, the integration of electronic products is getting higher and higher, and the circuit layer of the circuit board used in it has also increased from a single layer or 2 layers to 6 layers, 8 layers or even to More than 10 layers, so that electronic components can be more densely installed on the circuit board. However, with the increase in the number of layers of the circuit board and the densification of the lines, the electrical signals transmitted in the circuit board are more and more affected by the resistance and capacitance delay effect (RC delay) or the crosstalk effect (cross talk). more obvious. Therefore, passive components must be added to the circuit board in a limited configuration area to improve its electrical properties. ...
