Abstract:
1. A method comprising: (a) forming a lower electrode layer; (b) forming a dielectric layer over said lower electrode layer; (c) forming an upper electrode layer over said dielectric layer; (d) removing a portion of said upper electrode layer to expose said dielectric layer, thereby forming an upper electrode with a lateral boundary, wherein an inter-electrode region is disposed within said lateral boundary of said upper electrode and between said lower electrode layer and said upper electrode, and wherein a portion of said dielectric layer is disposed in said inter-electrode region; (e) removing a portion of said exposed portion of said dielectric layer to expose said lower electrode layer, whereby a portion of said dielectric layer is removed from said inter-electrode region; (f) subsequently forming a conformal insulating layer over said exposed portion of said lower electrode layer proximate to said portion of said dielectric layer disposed in said inter-electrode region, whereby a portion of said conformal insulating layer is formed in said inter-electrode region; and (g) subsequently forming an anti-reflective layer over said conformal insulating layer.
