Abstract:
A transistor region of a first semiconductor layer and a capacitor region in the first semiconductor layer are isolated. A dummy gate structure is formed on the first semiconductor layer in the transistor region. A second semiconductor layer is formed on the first semiconductor layer. First and second portions of the second semiconductor layer are located in the transistor region, and a third portion of the second semiconductor layer is located in the capacitor region. First, second, and third silicide regions are formed on the first, second, and third portions of the second semiconductor layer, respectively. After forming a dielectric layer, the dummy gate structure is removed forming a first cavity. At least a portion of the dielectric layer located above the third silicide region is removed forming a second cavity. A gate dielectric is formed in the first cavity and a capacitor dielectric in the second cavity.
