Patent number: 8361887Abstract: An antifuse having a link including a region of unsilicided semiconductor material may be programmed at reduced voltage and current and with reduced generation of heat by electromigration of metal or silicide from a cathode into the region of unsilicided semiconductor material to form an alloy having reduced bulk resistance. The cathode and anode are preferably shaped to control regions from which and to which material is electrically migrated. After programming, additional electromigration of material can return the antifuse to a high resistance state.

Patent number: 7745855Abstract: An integrated eFUSE device is formed by forming a silicon “floating beam” on air, whereupon the fusible portion of the eFUSE device resides. This beam extends between two larger, supporting terminal structures. “Undercutting” techniques are employed whereby a structure is formed atop a buried layer, and that buried layer is removed by selective etching. Whereby a “floating” silicide eFUSE conductor is formed on a silicon beam structure. In its initial state, the eFUSE silicide is highly conductive, exhibiting low electrical resistance (the “unblown state of the eFUSE). When a sufficiently large current is passed through the eFUSE conductor, localized heating occurs. This heating causes electromigration of the silicide into the silicon beam (and into surrounding silicon, thereby diffusing the silicide and greatly increasing its electrical resistance. When the current source is removed, the silicide remains permanently in this diffused state, the “blown” state of the eFUSE.Type: GrantFiled: October 4, 2007Date of Patent: June 29, 2010Assignee: International Business Machines CorporationInventors: William K.

Patent number: 7723820Abstract: The present invention provides structures for an integrated antifuse that incorporates an integrated sensing transistor with an integrated heater. Two terminals connected to the upper plate allow the heating of the upper plate, accelerating the breakdown of the antifuse dielectric at a lower bias voltage. Part of the upper plate also serves as the gate of the integrated sensing transistor. The antifuse dielectric serves as the gate dielectric of the integrated transistor. The lower plate comprises a channel, a drain, and a source of a transistor. While intact, the integrated sensing transistor allows a passage of transistor current through the drain. When programmed, the antifuse dielectric, which is the gate of the integrated transistor, is subjected to a gate breakdown, shorting the gate to the channel and resulting in a decreased drain current. The integrated antifuse structure can also be wired in an array to provide a compact OTP memory array.Type: GrantFiled: December 28, 2006Date of Patent: May 25, 2010Assignee: International Business Machines CorporationInventors: Deok-kee Kim, Byeongju Park, John M.

Patent number: 7714326Abstract: The present invention provides structures for antifuses that utilize electromigration for programming. By providing a portion of antifuse link with high resistance without conducting material and then by inducing electromigration of the conducting material into the antifuse link, the resistance of the antifuse structure is changed. By providing a terminal on the antifuse link, the change in the electrical properties of the antifuse link is detected and sensed. Also disclosed are an integrated antifuse with a built-in sensing device and a two dimensional array of integrated antifuses that can share programming transistors and sensing circuitry.Type: GrantFiled: March 7, 2007Date of Patent: May 11, 2010Assignee: International Business Machines CorporationInventors: Deok-kee Kim, Hoki Kim, Chandrasekharan Kothandaraman, Byeongju Park, John M.
