1. A package structure, comprising:
a circuit substrate, having a device region and a frame-shaped peripheral region around to the device region, wherein the circuit substrate comprises:
a dielectric portion; and
a conductive portion disposed in the dielectric portion, wherein a first ratio of a total volume of the conductive portion of the circuit substrate within the device region to a total volume of the dielectric portion and the conductive portion of the circuit substrate within the device region is less than a second ratio of a total volume of the conductive portion of the circuit substrate within the frame-shaped peripheral region to a total volume of the dielectric portion and the conductive portion of the circuit substrate within the frame-shaped peripheral region, wherein the second ratio is greater than or substantially equal to 80%, wherein in a cross section of the circuit substrate, the frame-shaped peripheral region has an inner sidewall and an outer sidewall opposite to the inner sidewall, the inner sidewall is in direct contact with a sidewall of the device region, and the outer sidewall is a sidewall of the circuit substrate;
a metallic supporting structure, disposed in and electrically isolated from the circuit substrate within the frame-shaped peripheral region;
a semiconductor device, disposed over the circuit substrate within the device region, wherein the semiconductor device is electrically coupled to the circuit substrate; and
a ring structure, disposed over the circuit substrate within the frame-shaped peripheral region.
