发明名称 MULTI-METAL GATE SEMICONDUCTOR DEVICE HAVING TRIPLE DIAMETER METAL OPENING
摘要 A method for manufacturing a semiconductor device and a device manufactured using the same are provided. A substrate with plural metal gates formed thereon is provided, wherein the adjacent metal gates are separated by insulation. A sacrificial layer is formed for capping the metal gates and the insulation, and the sacrificial layer and the insulation are patterned to form at least an opening for exposing the substrate. A silicide is formed corresponding to the opening at the substrate, and a conductive contact is formed in the opening. The conductive contact has a top area with a second diameter CD2 for opening the insulation. A patterned dielectric layer, further formed on the metal gates, the insulation and the conductive contact, at least has a first M0 opening with a third diameter CD3 for exposing the conductive contact, wherein CD2>CD3.
