  • Patent number: 8349682
    Abstract: An integrated method includes fabricating a metal gate transistor and a polysilicon resistor structure. A photoresistor layer is defined by an SAB photo mask and covers a part of a high resistance structure of the polysilicon resistor. When the dummy gate of the transistor is etched, the part of the high resistance structure is protected by the patterned photoresistor layer. The polysilicon resistor is formed simultaneously with the transistor. Furthermore, the polysilicon resistor still has sufficient resistance and includes two metal structures for electrical connection.
