Antifuse is a type of programmable chip technology that creates permanent conductive paths between transistors. Unlike traditional fusible link methods, antifuse technology grows a conductive layer over two metal layers and a layer of non-conductive amorphous silicon to close the circuit. When a voltage is applied, the amorphous silicon transforms into poly-silicon, which is conductive.
This technology can be controlled and programmed, allowing a high voltage to be applied to exceed the threshold and yield a logic or Boolean 1 when a control command is issued. Additionally, antifuse technology is capable of disconnecting circuits or shutting them down in the event of an issue. Instead of installing and replacing fuses, linear and clocked power supply regulation can be utilized to reduce voltage or current spikes and circuit breakers that can be externally reset.
Frequently Asked Questions (FAQ)
What is the difference between antifuse and fuse technology?
Antifuse technology creates permanent conductive paths between transistors, while fuse technology breaks the conductive path to open a circuit. Additionally, antifuse technology can be controlled and programmed, while fuse technology requires a replacement after it is blown.
What is the benefit of using antifuse technology?
The benefit of using antifuse technology is the ability to create permanent conductive paths between transistors and the ability to disconnect or shut down circuits without needing to replace fuses. This technology can also be controlled and programmed for specific commands.
How does antifuse technology disconnect circuits?
Antifuse technology can disconnect circuits by utilizing linear and clocked power supply regulation to reduce voltage or current spikes and by using external circuit breakers that can be reset.
Conclusion
Antifuse technology is a programmable chip technology that creates permanent conductive paths between transistors. It is controlled and programmed, making it a versatile and efficient option. Additionally, it is capable of disconnecting circuits without the need for replacing fuses, reducing maintenance needs and improving overall functionality.
