One-time programmable devices and methods of forming the same

A one-time programmable (OTP) device includes at least one transistor that is electrically coupled with a fuse. The fuse includes a silicon-containing line continuously extending between a first node and a second node of the fuse. A first silicide-containing portion is disposed over the silicon-cont...

Zusammenfassung:A one-time programmable (OTP) device includes at least one transistor that is electrically coupled with a fuse. The fuse includes a silicon-containing line continuously extending between a first node and a second node of the fuse. A first silicide-containing portion is disposed over the silicon-containing line. A second silicide-containing portion is disposed over the silicon-containing line. The second silicide-containing portion is separated from the first silicide-containing portion by a predetermined distance. The predetermined distance is substantially equal to or less than a length of the silicon-containing line.
