Abstract
A heat dissipation substrate includes an insulating layer, a metal heat dissipation block, and a patterned structure layer. The insulating layer has a first surface, a second surface and at least one through hole. The metal heat dissipation block passes through the insulating layer from the second surface of the insulating layer and has an upper surface, a lower surface, and a contact surface. There is a first vertical height between the contact surface and the lower surface. The patterned structure layer includes a patterned circuit layer and at least one conductive structure layer. The patterned circuit layer is disposed on the first surface of the insulating layer, and the conductive structure layer is connected to the patterned circuit layer and extends to cover an inner wall of the through hole. The patterned circuit layer has a top surface, the conductive structure layer has a bottom surface. There is a second vertical height between the top surface and the first surface, and the first vertical height is 3 times to 300 times the second vertical height.
