“…5. The system is similar to the IXL system, at the Université Bordeaux, France [31]- [33]. At the center of the system is a tunable Spectra-Physics Ti: sapphire mode-locked Tsunami laser pumped by a 5 W Millennia Pro5s laser at 532 nm (frequency doubled from Nd: YAG diodes).…”

Spatially-resolved picosecond laser induced transients have been measured in a 0.18 m CMOS inverter test structure as a function of temperature. Sensitive -drain and -drain nodes have been scaled in size to accommodate characteristic differences between ion and laser tracks. Images based on pulse characteristics have been collected from 325 K to 400 K and transient currents extracted from laser strikes to both the OFF drain and its surroundings. With increasing temperature strikes to the OFF drain result in a pulse width which appears to broadens whilst the charge collected surprisingly decreases.

“…We refer to transients that drop below base line as negative going transients. The negative-going transients have longer duration, typically [10][11][12][13][14][15] and only occur for capacitive filter of 0.1 . The output waveform voltage starts to recover with a damped oscillatory behavior that persists for several microseconds.…”
Single-event transients (SETs) from heavy ions and laser beam are investigated for two positive adjustable linear voltage regulators: the RH117 from Linear Technology and the HS-117RH from Intersil. Both positive and negative going transients are observed. The role of input voltage, load capacitance and supply current on the SET response is discussed.
“…But DLS does not provide any knowledge on when the laser causes such a change in the test result. Temporal information could be provided by targeting specific vectors or transitions with the help of a modulated laser beam [18,19]. In such a scheme the laser is turned on or off during different part of the test pattern.…”
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
