An Antifuse programming technology is predominantly associated with _____. Antifuse technology is nonvolatile, so it is live at power-up and programming services, either from Actel or from other vendors, are also used. recommended programming practices for antifuse devices. For SoC Antifuse technology is nonvolatile, so it is live at power-up and inherently very secure.

The conductive shunt therefore does not compromise integrity and reliability of the semiconductor device. This technology has many applications.
In the same fashion as with the Christmas lights described above, if the lamp failed, the entire voltage of the street lighting circuit thousands of volts was imposed across the insulating film in the cutout, causing it to rupture. This page was last edited on 7 Julyat Because the series string would be rendered inoperable by a single lamp failing, each bulb has an antifuse installed within it.
Unsourced material may be challenged and removed. Each individual street-lamp was equipped with a film cutout ; a small disk of insulating film that separated two contacts connected to the two wires leading to the lamp.
Antifuses are widely technolofy to permanently program integrated circuits ICs. A specialized structure optimized for the purpose can be employed where the antifuse is an integral part of the design. Zener diodes can be used as antifuses. They are historically used anttifuse with bipolar processes, where the thin oxide needed for dielectric antifuses is not available.
FPGAs in computer
Occasionally, technollgy insulation fails to break down on its own, but tapping the blown lamp will usually finish the job. With a poly-diffusion antifuse, the high current density creates heatwhich melts a thin insulating layer between polysilicon and diffusion electrodes, creating a permanent resistive silicon link.
One approach for the ICs that use antifuse technology employs a thin barrier of non-conducting amorphous silicon between two metal conductors. An antifuse is an electrical device that performs the opposite function to a fuse. Their disadvantage, however, is lower area efficiency compared to other types. Please help improve this article by adding citations to reliable sources.
When a sufficiently high voltage is applied across the amorphous silicon it is turned into a polycrystalline silicon-metal alloy with a low resistancewhich is conductive.
Articles needing additional references from May All articles needing additional references. When the failed lamp was finally changed, a new piece of film was also installed, once again separating the electrical contacts in tschnology cutout.
It is therefore necessary to shift the manufacturing tolerances so antifise the lowest-value typically made is equal to or larger than the desired value. Antifuses may be used in programmable read-only memory PROM. Amorphous silicon is a material usually not used in either bipolar or CMOS processes and requires an additional manufacturing step.
May Learn programing and when to remove this template message. A standard NPN transistor structure is often used in common bipolar processes as the antifuse.
Antifuse programming technology – FPGAs
Views Read Edit View history. In this way, the failed lamp was bypassed and illumination restored to the rest of the street. The resulting resistance of the junction is in the range of 10 ohms. They may be less susceptible to alpha particles which can cause circuits to malfunction.
The antifuse is atifuse triggered using an progrqmming 5 mA current. This programming, performed after manufacturing, is permanent and irreversible. The technoogy resistors cannot have too low value as that would sink the zapping current; a series-parallel combination of resistors and antifuses is employed in such cases. Retrieved from ” https: In a similar fashion to that of Christmas tree lights, before the advent of high-intensity discharge lampsstreet light circuits using incandescent light bulbs were often operated as high-voltage series circuits.
The terminals of the antifuses are usually accessible as bonding pads and the trimming process is performed before wire-bonding and encapsulating the chip. From Wikipedia, the free encyclopedia. Certain programmable logic devices PLDssuch as structured ASICsuse antifuse technology to configure logic circuits and create a customized design from a standard IC design.
