Abstract
A set () of laser pulses () is employed to sever a conductive link () in a memory or other IC chip. The duration of the set () is preferably shorter than 1,000 ns; and the pulse width of each laser pulse () within the set () is preferably within a range of about 0.1 ps to 30 ns. The set () can be treated as a single 'pulse' by conventional laser positioning systems () to perform on-the-fly link removal without stopping whenever the laser system () fires a set () of laser pulses () at each link (). Conventional IR wavelengths or their harmonics can be employed.
