Abstract: PROBLEM TO BE SOLVED: To prevent short-circuit between wiring films which is to be caused by a side wall, by eliminating dust on the interlayer insulating film or making the dust fine, by resist coating and its etching-back, before an aperture is formed after the interlayer insulating film is formed. SOLUTION: A lower layer wiring film 2 is formed, a plasma TEOS film 3 turning to an interlayer insulating film is formed, an SOG film 4 for flattening is formed, and then a plasma TEOS film 5 turning to an interlayer insulating film is formed. But a large dust clod 9 is generated on the plasma TEOS film 5. By spreading a resist film 11 and etching back it, the dust clod 9 is eliminated or made fine. The possibility that a side wall composed of tungsten is generated by forming a tungsten film 7 for filling a through hole 6 and by etching the film 7 is excluded. Thereby short-circuit between wiring films 8 which is to be caused by a side wall 10 composed of tungsten on the dust clod 9 side surface can be prevented, so that yield can be improved.

Title: Method for preventing breakdown of internal diode of mosfet
Inventor: KURATA IWAO
IPC: H02M7/537
Filed: 1995-01-25
Abstract: PURPOSE:To prevent the breakdown of the internal diode of a MOSFET by interrupting the gate signal of the MOSFET when it is detected that the frequency of the output current of an inverter device becomes higher than a prefixed value. CONSTITUTION:In case the frequency of an output current I0 abruptly rises, because such an abnormal state as the short circuit of a reactor constituting a load 8, etc., occurs and the circuit constant of the load 8 abruptly changes, the time from the zero-crossing point immediately before the occurrence of the abnormality to the zero-crossing point immediately after the occurrence of the abnormality becomes shorter. Therefore, at least one of two counters counts the second zero-crossing point before the resetting timing comes and the count value of the counter becomes '2'. A control circuit 9 interrupts all gate signals to MOSFETs 11-14 so as to prevent reverse recovery currents from flowing to the internal diodes 11a-14a of the MOSFETs 11-14.
