Patent number: 9628086Abstract: An antifuse apparatus can include a cantilever extending from a first electrode portion to terminate in a distal end. A second electrode portion can be spaced apart from the cantilever by an air gap. In response to a program voltage across the first and second electrode portions, the cantilever can be adapted to move from an unprogrammed condition, corresponding to an open circuit condition where the cantilever is spaced apart from the second electrode portion, to at least one permanent programmed condition, corresponding to a short circuit condition between the first and second electrode portions where the cantilever engages the second electrode portion.Type: GrantFiled: November 14, 2014Date of Patent: April 18, 2017Assignee: Case Western Reserve UniversityInventors: Ting He, Fengchao Zhang, Swarup Bhunia, Philip X. -L.
