发明名称 Semiconductor manufacturing-and-inspection system, and semiconductor device
摘要 The peak of the current dissipated by semiconductor devices is dispersed and suppressed to a level below the current supply capability of a burn-in apparatus. As a result, there is obtained a semiconductor manufacturing-and-inspection apparatus which enables easy performance of a burn-in test without involvement of anomalies arising in the burn-in apparatus or limitations on the number of semiconductor devices mounted on the burn-in board. A semiconductor manufacturing-and-inspection system, which tests semiconductor devices provided in a plurality of areas on a burn-in board through use of a burn-in apparatus, includes a driver for supplying a drive signal to the semiconductor devices provided in the plurality of areas, a delay circuit which is provided for one of a plurality of drive signals output from the signal generation apparatus and delays the drive signal relative to the other drive signal; and a driver for controlling the delaying operation of the delay apparatus.
