Abstract:
A method of manufacturing a semiconductor device is provided. The method includes depositing a first interconnect metal layer on a substrate; depositing a first barrier metal layer on the first interconnect metal layer; depositing a first dielectric layer on the first barrier metal layer; depositing a second barrier metal layer on the first dielectric layer; etching the second barrier metal layer to form a MIM capacitor region and a thin film resistor region; forming a hard mask on the second barrier metal layer and the first dielectric layer; forming an isolated interconnect pattern between the MIM capacitor region and the thin film resistor region; depositing an inter-metal dielectric layer on the hard mask; forming Via holes in the MIM capacitor region and the thin film resistor region, and filling the Via holes with metal to form a Via contact layer.
