摘要： A metal layer and a semiconductor layer are sequentially deposited on a substrate. The semiconductor layer and the metal layer are lithographically patterned to form a stack of a semiconductor portion and a metal gate portion, which is preferably performed concurrently with formation of at least one metal gate stack. In one embodiment, the size of the semiconductor portion is reduced and a metal semiconductor alloy portion is formed on the semiconductor portion by metallization. In a first electrical antifuse formed thereby, the metal semiconductor alloy portion may be electromigrated to form a short between the metal semiconductor alloy portion and the metal gate portion. In another embodiment, two disjoined metal semiconductor alloy portions are formed on the semiconductor portion. In a second electrical antifuse formed thereby, the metal semiconductor alloy portion may be electromigrated to form a short between the two previously disjoined metal semiconductor alloy portions.

摘要： An antifuse has first and second semiconductor regions having one conductivity type and a third semiconductor region therebetween having an opposite conductivity type. A conductive region contacting the first region has a long dimension in a second direction transverse to the direction of a long dimension of a gate. An antifuse anode is spaced apart from the first region in the second direction and a contact is connected with the second region. Applying a programming voltage between the anode and the contact with gate bias sufficient to fully turn on field effect transistor operation of the antifuse heats the first region to drive a dopant outwardly, causing an edge of the first region to move closer to an edge of the second region and reduce electrical resistance between the first and second regions by an one or more orders of magnitude.

摘要： An antifuse is provided having a unitary monocrystalline semiconductor body including first and second semiconductor regions each having the same first conductivity type, and a third semiconductor region between the first and second semiconductor regions which has a second conductivity type opposite from the first conductivity type. An anode and a cathode can be electrically connected with the first semiconductor region. A conductive region including a metal, a conductive compound of a metal or an alloy of a metal can contact the first semiconductor region and extend between the cathode and the anode. The antifuse can further include a contact electrically connected with the second semiconductor region. In this way, the antifuse can be configured such that the application of a programming voltage between the anode and the cathode heats the first semiconductor region sufficiently to reach a temperature which drives a dopant outwardly therefrom, causing an edge of the first semiconductor region to move closer to an adjacent edge of the second semiconductor region, thus permanently reducing electrical resistance between the first and second semiconductor regions by one or more orders of magnitude.
