<p>PURPOSE:To enable the function trimming of a passive element, and improve reliability and yield. CONSTITUTION:A heat generating element 4, a control circuit element 5 and a passive element 2 are mounted on a main surface of lead frame 1 integrated in a body with a heat sink, and are coated with mold resin 3. Since the part corresponding to the passive element 2 is not coated with the mold resin 3, the function trimming of the passive element 3 is enabled after coating. The part corresponding to the passive element 2 may be coated with, e.g. mold resin 3 after trimming.</p> |
