Abstract:
1. A semiconductor device, comprising: a semiconductor body of a first semiconductive material; a transistor disposed in the semiconductor body, the transistor including a semiconductive gate region comprising the first semiconductive material and source and drain regions of a second semiconductive material, wherein the first semiconductive material and the second semiconductive material are different types of material, wherein the source and drain regions are embedded in the semiconductor body; a semiconductive resistor overlying a top surface of the semiconductor body and laterally spaced from the transistor, the resistor comprising the second semiconductive material, the resistor and the gate region being a different type of semiconductor material, and the resistor and the source and drain regions being a same type of semiconductor material; a gate dielectric layer overlying the top surface of the semiconductor body, wherein the resistor overlies the gate dielectric layer; a first silicide region embedded at a first end of the semiconductive resistor; a second silicide region embedded at a second end of the semiconductive resistor; and an insulator layer contacting and covering a top surface of the semiconductive resistor, wherein a structure comprising the resistor is embedded in the insulator layer.
