Patent ID: 8530319

Claim:
A method of manufacturing an e-fuse comprising: patterning an insulator on a substrate; patterning a conductor on said insulator, said conductor having a top and sidewalls; covering said insulator and at least one of said sidewalls of said conductor with a first insulating spacer; covering said top of said conductor with an insulating cap; covering said first insulating spacer with a second insulating spacer; removing said insulating cap; removing said second insulating spacer and said first insulating spacer from one side of said insulator and said conductor; forming a silicide on said top and one sidewall of said conductor, said insulator, and a region of said substrate adjacent said insulator, said one sidewall being free of insulating spacers, and said region of said substrate being adjacent said one sidewall; providing a first electrical contact on said silicide over said top of said conductor; and providing a second electrical contact on said silicide over said region of said substrate adjacent said insulator.
