Patent ID: 7911025

Claim:
A fuse/anti-fuse structure adapted to transition between a first state and a second state, comprising: an inner conductor structure, said inner conductor structure, in said first state, being electrically open and defining a gap, said inner conductor structure being adapted to become electrically conductive in said second state; an insulating layer spaced outwardly of said inner conductor structure; an outer conductor structure disposed outwardly of said insulating layer, said outer conductor structure, in said first state, being electrically conductive, said outer conductor structure being adapted to become electrically open in said second state; and a cavity-defining structure that defines at least one cavity, at least a portion of said cavity-defining structure being formed from at least one of said inner conductor structure, said insulating layer, and said outer conductor structure, said at least one cavity being located substantially adjacent said gap defined in said inner conductor structure.
