Abstract
As devices are often different in the characteristics from one another, semiconductor chips based on the devices have discrepancies in the performance. A semiconductor device having a semiconductor switching element and a drive controlling means () for generating from input signals (A) and (B) drive signals (a) and (b) to control the action of the semiconductor switching element is provided comprising a characteristic compensating means () for generating from a characteristic compensation input signal a compensation signal to eliminate variations in the transmission delay time of the drive controlling means ().
