A semiconductor apparatus includes a MOS transistor and a resistive element having insulative first polysilicon and conductive second polysilicon films, an insulating film for a resistive element, and a third polysilicon film. The second polysilicon film is formed in a region adjacent each side edge of the first polysilicon film, and has a contact hole formed therein. The third polysilicon film determines a resistance value of the resistive element, and is continuously formed on the second polysilicon film and the insulating film formed on the first polysilicon film. The MOS transistor is formed in an active region surrounded by the field insulating film, and includes a gate oxide film and a gate electrode including a polysilicon film formed as a lower layer with the second polysilicon film and a polysilicon film formed as an upper layer with the third polysilicon film. A method of making this semiconductor apparatus is also described.
