<P>PROBLEM TO BE SOLVED: To enhance reliability by stabilizing gate voltage, even at high voltage, high current, preventing current nonuniformity and oscillation, and the like, thereby protecting the device against breakdowns. <P>SOLUTION: In the method for controlling the semiconductor device, having two main electrodes and a control electrode part which controls current between the main electrodes, in a detection process, an amount of charge accumulated at the control electrode part is detected, based on voltage of the control electrode part. In a control process, voltage applied to the control electrode part and/or current flow to the control electrode part is controlled, based on the amount of charge detected by the detecting process. <P>COPYRIGHT: (C)2007,JPO&INPIT |
