HEAT-RADIATING SUBSTRATE AND METHOD OF MANUFACTURING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a heat-radiating substrate capable of protecting a thermally weakened element from the heat generated from a heat generating element, while maintaining heat-radiating characteristics, and a method of manufacturing the same.

SOLUTION: The heat-radiating substrate includes a core layer 110 including a core metal layer 111 and a core insulating layer 112 formed on the core metal layer 111 and divided into a first region and a second region; a circuit layer 120 formed in the first region of the core layer 110; and a build-up layer 130 formed in the second region of the core layer 110 and including a build-up insulating layer 131 and a build-up circuit layer 132. A heat generating element 150 is mounted on the circuit layer 120 and a thermally weakened element 151 is mounted on the build-up layer 130, thereby preventing the thermally weakened element 151 from being damaged by the heat generated from the heat generating element 150.
