Abstract
PURPOSE: To obtain an output power more reliable than a CuHS-structure element and approximately equivalent to this element by using Ia-type diamond as a heating body.
CONSTITUTION: In DHS structure, the position of pedestal 22 is separated from semiconductor chip 21 because of the interposition of diamond 24, and the heat generated in semiconductor chip 21 extends up to the lower face of diamond 24 and reaches pedestal 22, and as a result, the temperature rise of pedestal 22 does not become large, and it is hard to generate the deterioration of the thermal resistance of the element. Meanwhile, by adopting Ia-type diamond, merits on the reliability of DHS structure are used effectively, and an element superior in the thermal resistance approximately equivalent to CuHS structure can be obtained.
