Abstract:
A method of fabricating a metal-insulator-metal capacitor (MIMCap), comprising:providing a wafer having a workpiece; depositing a first insulating layer over the workpiece; forming a plurality of first conductive lines within the first insulating layer, the first conductive lines comprising a first conductive material; depositing a second insulating layer; depositing a resist over the second insulating layer; patterning the resist with a predetermined pattern; removing portions of the resist to expose portions of the second insulating layer; removing at least the exposed second insulating layer and portions of the first insulating layer, leaving portions of the first conductive lines exposed; removing the remaining resist; depositing a capacitor dielectric over the first conductive lines; and depositing a second conductive material over the capacitor dielectric to form second conductive lines.
