Disclosed herein are a heat-radiating substrate and a method of manufacturing the same. The heat-radiating substrate includes: a base substrate with a heat sink, having a groove; an insulating layer formed on the base substrate by performing anodization thereon; and a circuit layer formed on the insulating layer, whereby the heat-radiating substrate with the heat-sink, made of metal material, is manufactured, thereby making it possible to protect devices weak against heat and thus solve the problem in view of reduced life span and degraded reliability.

Disclosed herein is a metal clad laminate, a method of manufacturing the same and a heat-radiating substrate using the same. The metal clad laminate has increased adhesion because a layer of carbon nanoparticles is formed between bonding surfaces of upper and lower metal foils to a prepreg, and has improved heat conductive properties and mechanical properties because the prepreg has carbon fibers incorporated therein. Also, resin members having carbon nanofibers incorporated therein may be alternately stacked with metal layers, and metal layers may be inserted in the prepreg thus improving heat conductive properties, and the number of stacked layers may vary depending on the end use thereby controlling heat conductive properties and mechanical properties of the metal clad laminate.

Disclosed herein is a transformer integrated with an inductor. The transformer includes a transformer unit configured to perform voltage transformation by mutual induction between first and second cores connected opposite to each other and primary and secondary coils included in a space between the first core and the second core; and an inductor unit having a third core connected to the second core and an inductor included in a space between the second core and the third core. The transformer is fabricated by physically integrating two elements having different functions into one element, thereby simplifying the configuration of a system.
