    摘要: 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.

    摘要: A semiconductor device including a substrate, a first device, a second device and an interlayer dielectric layer is provided. The substrate has a first area and a second area. The first device is disposed in the first area of the substrate and includes a first dielectric layer on the substrate and a metal gate on the first dielectric layer. The second device is in the second area of the substrate and includes a second dielectric layer on the substrate and, a polysilicon layer on the second dielectric layer. It is noted that the height of the polysilicon layer is less than that of the metal gate of the first device. The interlayer dielectric layer covers the second device.

    摘要: A method for fabricating metal gate transistor and resistor is disclosed. The method includes the steps of: providing a substrate having a transistor region and a resistor region; forming a shallow trench isolation in the substrate of the resistor region; forming a tank in the shallow trench isolation of the resistor region; forming at least one gate in the transistor region and a resistor in the tank of the resistor region; and transforming the gate into a metal gate transistor.
