In a high frequency flip chip package process of a polymer substrate and a structure thereof, the structure is a one-layer structure packaged by a high frequency flip chip package process to overcome the shortcomings of a conventional two-layer structure packaged by the high frequency flip chip package process. The conventional structure not only incurs additional insertion loss and return loss in its high frequency characteristic, but also brings out a reliability issue. Thus, the manufacturing process of a ceramic substrate in the conventional structure still has the disadvantages of a poor yield rate and a high cost.

A vertical transmission structure for high frequency transmission lines includes a conductive axial core and a conductive structure surrounding the conductive axial core. The vertical transmission structure is applied to a high-frequency flip chip package for reducing the possibility of underfill from coming in contact with the conductive axial core.
