发明名称 Semiconductor device
摘要 Provided is a semiconductor device, in which: patterns for detecting displacement at probing are formed of a plurality of minute conductors formed below a protective film; each of the plurality of minute conductors formed below the protective film is electrically insulated and formed to be smaller than a bottom surface of a tip of a probing needle used for carrying out an electrical measurement of IC chips; and the patterns for detecting displacement at probing are provided in a pair for each of the IC chips.
