Abstract

The invention provides a circuit board structure and a manufacturing method thereof. The circuit board structure includes an insulating layer, a first circuit layer and a second circuit layer on opposite sides of the insulating layer, and the insulating layer is penetrated to electrically connect the first circuit layer and the second circuit layer. Conductive vias, capacitor dielectric layers, dielectric layers and redistributed circuit layers of the circuit layer. The first wiring layer includes a first capacitor electrode. The capacitive dielectric layer is located on the first capacitive electrode. The dielectric layer covers the first circuit layer and the capacitor dielectric layer. The redistributed circuit layer includes a redistributed circuit on the dielectric layer, a first conductive blind hole located in the dielectric layer and connected to the first circuit layer, and a second capacitor electrode located in the dielectric layer. Two ends of the second capacitor electrode are respectively in contact with the capacitor dielectric layer and the redistribution line. The second capacitor electrode, the capacitor dielectric layer and the first capacitor electrode constitute a capacitor.

Description

Technical field [0001] The present invention relates to a circuit board structure and a method thereof, in particular, to a circuit board structure having a capacitor and a method of fabricating it. Background technique [0002] With the demand of electronic products, the stronger the function of the function of the signal transmission is high speed and circuit components, and the number of passive components that is combined with the consumer electronics is also increased. Furthermore, in the electronics emphasize the light and short, how to accommodate the large number of electronic components in a limited consolidation space, which has become an electronic confession, an eunuch, a technology bottleneck, and overcoming technology. In order to solve this problem, the configuration technique gradually went to the system integration phase of the SMS IN Package; SIP, especially the package of multi-chipmodule; MCM. Among them, inner bury active components and passive components tec...
