Semiconductor Device"
Abstract: A scale-like portion (3) wherein metal plating is changed into a scale-like form is provided by continuously carrying out laser spot irradiation on a lead frame (2) , the front surface of which is coated with the metal plating. The scale-like portion (3} is disposed in an optional portion of the lead frame (2) , for example, in the vicinity of a gate break mark (8a), in an outer peripheral portion in a region sealed with a molding resin (8), or around a semiconductor element (1) . The adhesion between the lead frame (2) and the molding resin (8) improves owing to the anchor effect of the scale-like portion (3), and it is thus possible to suppress the molding resin (8) separating from the lead frame (2).
