A method of manufacturing a capacitor and a metal gate on a semiconductor device comprises forming a dummy gate on a substrate, forming a trench layer on the substrate and adjacent the dummy gate, forming a capacitor trench in the trench layer, forming a bottom electrode layer in the capacitor trench, removing the dummy gate to provide a gate trench, forming a dielectric layer in the capacitor trench and the gate trench, and forming a metal layer over the dielectric layer in the capacitor trench and the gate trench.
