摘要:In a semiconductor device, a lead frame is adhered to a base substrate for heatdissipation via an insulating layer, and an outward guided terminal portion is formed byperpendicularly upwardly bending an end of the lead frame after the mounting of one or
more of power semiconductor elements on the lead frame. A recessed portion is formedbeforehand in a portion of the lead frame to be bent, and it is ensured that the leadframe does not adhere to the surface of the base substrate in this recessed portion whenthe lead frame is adhered to the base substrate via the insulating layer before thebending of the lead frame. By virtue of this structure, manufacturing is simplified andmanufacturing costs are reduced.
