Heat-dissipating substrate structure with built-in conductive circuits

Abstract

A heat-dissipating substrate structure with built-in conductive circuits is provided. The heat-dissipating substrate structure includes an electrically insulating layer, a first metal layer, a second metal layer, and a heat-dissipating layer. The first metal layer and the second metal layer are disposed on the heat-dissipating layer at an interval. The electrically insulating layer encloses and is in contact with side walls of the first metal layer and side walls of the second metal layer, such that a top wall of the first metal layer and a top wall of the second metal layer are exposed from the electrically insulating layer, and at least one of the conductive circuits extends through at least one of the side wall of the first metal layer and the side wall of the second metal layer and is embedded in the electrically insulating layer.
