Structural pattern extraction from asynchronous two-photon laser fault injection using spectral analysis.

This paper presents a methodology for analysing two-photon absorption laser testing results in the frequency domain rather than with the classical mapping approach. We experimentally demonstrate, on a 28 nm device, the extraction of subwavelength dimensions from a noisy environment without requiring any synchronization between the test operations and the laser or the scan motion. A model of the experiment is then used to evaluate the impact of different parameters on the capabilities of the technique. [ABSTRACT FROM AUTHOR]
