PROBLEM TO BE SOLVED: To provide an excellent semiconductor device capable of suitably radiating heat generated in a semiconductor element, in a semiconductor device mounting a semiconductor element such as an LED, and to provide a method of manufacturing the same.SOLUTION: A semiconductor device comprises: a supporting substrate 11; an insulating layer 13 formed on the supporting substrate and formed of boron nitride; and a semiconductor element 30 arranged on the insulating layer. The insulating layer has: a lower insulating layer formed on the supporting substrate and formed of amorphous boron nitride not containing boron nitride grains with a hexagonal structure; and an upper insulating layer formed on the lower insulating layer and that contains boron nitride grains with a hexagonal structure.SELECTED DRAWING: Figure 2 |
