A gate may overlie the body and a body contact is electrically connected with the body. The first regions have opposite conductivity (i.e., n-type or p-type) from the body. The IGFET can be configured such that a programming current through at least one of the first regions and the body contact causes heating sufficient to drive dopant diffusion from the at least one first region into the body and cause an edge of the at least one first region to move closer to an adjacent edge of at least one other of the first regions. In such way, the programming current can permanently reduce electrical resistance by one or more orders of magnitude between the at least one first region and the at least one other first region. | 12-13-2012 |
20120327700 | LOW VOLTAGE METAL GATE ANTIFUSE WITH DEPLETION MODE MOSFET - An antifuse according to an embodiment of the invention herein can include a depletion mode metal oxide semiconductor field effect transistor (“MOSFET”) having a conduction channel and a metal gate overlying the conduction channel. A cathode and an anode of the antifuse can be electrically coupled to the gate and spaced apart from one another in a direction the gate extends, such that the antifuse is programmable by driving a programming current between the cathode and the anode to cause material of the metal gate to migrate away. The gate may be configured such that, under appropriate biasing conditions, when the antifuse is unprogrammed, the conduction channel is turned on unless a voltage above a first threshold voltage is applied to the gate to turn off the conduction channel. The gate can be configured such that when the antifuse has been programmed, the conduction channel remains turned on even if a voltage above the first threshold voltage is applied between the gate and a source region of the MOSFET. | 12-27-2012 |
20130063202 | SECURE ANTI-FUSE WITH LOW VOLTAGE PROGRAMMING THROUGH LOCALIZED DIFFUSION HEATING - 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. | 03-14-2013 |
20130071998 | Electrical Fuse With Metal Line Migration - An electrical fuse device is disclosed. A circuit apparatus can include the fuse device, a first circuit element and a second circuit element. The fuse includes a first contact that has a first electromigration resistance, a second contact that has a second electromigration resistance and a metal line, which is coupled to the first contact and to the second contact, that has a third electromigration resistance that is lower than the second electromigration resistance. The first circuit element is coupled to the first contact and the second circuit element coupled to the second contact. The fuse is configured to conduct a programming current from the first contact to the second contact through the metal line. Further, the programming current causes the metal line to electromigrate away from the second contact to electrically isolate the second circuit element from the first circuit element. | 03-21-2013 |

By non-conformal deposition of a dielectric film over raised structures, a 3d confined tube, which may be sub-lithographic, is formed between the raised structures. Etching holes which intersect the 3d confined region and subsequent metal deposition fills the 3d confined region and forms contacts. When the raised structures are gates, the fuse element may be located at the middle of the line (i.e. in pre-metal dielectric). Other methods for creating the structure are also described. | 02-12-2015 |
