摘要: An object of the present invention is to improve the quality control of a semiconductor device. By forming an inscription comprising a culled or pixel skipping pattern of dimples on the upper surface of a die pad in a QFN, it is possible to confirm the inscription by X-ray inspection or the like even after individuation and specify a cavity of a resin molding die. Further, it is possible to specify the position of a device region in a lead frame. As a result, when a defect appears, it is possible to sort a defective QFN by appearance inspection and improve quality control in the assembly of a QFN.
