Problems solved by technology

[0004] Therefore, there is an urgent need for an innovative embedded capacitance element structure and its manufacturing method, which can enhance the capacitance characteristics of the embedded capacitance element without increasing the thickness of the package substrate for die carrying, thereby overcoming the existing embedded capacitance. In order to increase the capacitive characteristics of the device, the thickness of the package substrate for die mounting is greatly increased.

Abstract

The disclosed base plate includes interlaid circuit board of possessing first conducting circuit, dielectric layer, first electrode, second electrode, and second conducting circuit. Being setup on the interlaid circuit board, the dielectric layer possesses first concave hole and second concave hole. First electrode is setup in the first concave hole, and the second electrode is setup in the second concave hole. The first and second electrodes as well as the dielectric layer located between first electrode and second electrode constitute an embedded passive element jointly. Second conducting circuit connects first electrode and second electrode electrically.

Description

technical field [0001] The invention relates to a packaging structure and a manufacturing method thereof, in particular to a packaging substrate for carrying a die with embedded passive elements and a manufacturing method thereof. Background technique [0002] The embedded capacitor element structure is a structure in which the capacitor is embedded in the substrate with a dielectric material by using a multi-layer circuit board package (Multiple Stacked Package; MSP) technology according to the circuit characteristics and requirements of the module. In actual application, substrate materials with different dielectric numbers and resistances can be used in the design of embedded capacitors, resistors, or high-frequency transmission lines according to circuit characteristics and requirements. Through the assembly and integration of embedded component substrate technology, the circuit layout and signal transmission distance are shortened to improve the performance of the overa...
