Abstract
The present invention is directed to enhancing the analysis and modification of a flip chip integrated circuit die having silicon on insulator (SOI) structure. According to one example embodiment, an optical nanomachining arrangement is adapted to direct an optical beam, such as a laser, at a selected portion of the flip chip SOI structure. The optical beam performs device edits to modify the circuitry contained in the SOI selected portion without necessarily damaging surrounding circuitry. The ability to make such device edits is advantageous for various applications, such as in dies of complex, circuitry containing multiple stacked layers of components, and for dies having densely packed circuitry.
