Abstract:
A semiconductor device, comprising:a semiconductor substrate covered with a field insulating film; a resistive element formed over the field insulating film, including: an insulative first polysilicon film formed over the field insulating film; a conductive second polysilicon film formed adjacent each side edge of the insulative first polysilicon film; a resistive-element-aimed insulating film formed over the insulative first polysilicon film; and a third polysilicon film for determining a resistance value of said resistive elements, formed in a continuous manner over the conductive second polysilicon film and the resistive-element-aimed insulating film, and a metal oxide semiconductor transistor formed in an active region surrounded by the field insulating film on the semiconductor substrate, including: a gate oxide film; and a gate electrode formed over the gate oxide and including a multi-layered film comprising: a polysilicon film formed over the gate oxide as a lower layer when the conductive second polysilicon film is formed; and a polysilicon film formed over the lower layer as an upper layer when the third polysilicon film is formed.
