Abstract:
1. A method of forming an embedded metal-insulator-metal (MIM) capacitor for a semiconductor device, the method comprising: forming a first patterned photo-resist layer above a first dielectric layer above a substrate, the first patterned photo-resist layer comprising a first pattern of lines along a first direction; hardening the first patterned photo-resist layer; and, subsequently, forming a second patterned photo-resist layer above the first patterned photo-resist layer, the second patterned photo-resist layer comprising a second pattern of lines along a second direction different from the first direction; forming a trench in the first dielectric layer using both the first patterned photo-resist layer and the second patterned photo-resist layer as a mask; and forming the capacitor in the trench.
