发明名称 Semiconductor device
摘要 A semiconductor device comprises a MOS transistor and a resistor. The resistor has a P-type resistor formed from a P-type semiconductor, an N-type resistor formed from an N-type semiconductor and disposed adjacent the P-type resistor, and an insulating film disposed between the P-type and N-type resistors. The P-type resistor is arranged at the low potential side of the semiconductor device and the N-type resistor is arranged at the high potential side thereof. A portion of the insulating film between the P-type and N-type resistors is made electrically conductive by irradiating the portion with a laser beam to destroy the insulating property thereof to thereby achieve conductivity between the P-type and N-type resistors. A gate electrode of the MOS transistor is formed of a P-type polysilicon thin film having the same high concentration impurity as that of the region where the P-type resistor is in contact with a metal wiring, thereby enhancing the current driving capacity of a driver MOS.
