Investigation on the SEL Sensitive Depth of an SRAM Using Linear and Two-Photon Absorption Laser Testing

Comparison of classical and two-photon photoelectric laser stimulation capabilities for failure analysis

“…As we mentioned before, the TPA laser stimulation has not only better lateral resolution but also more confined axial region than in single photon stimulation, whichopens interesting applications like SEU sensitive volume characterization [13]. In order to use the axial resolution of TPA stimulation, understanding of its complex nonlinear propagation effect and carrier collection mechanism is essential.…”

Investigation on the Single Event Burnout Sensitive Volume Using Two-Photon Absorption Laser Testing

“…The depth of the SEB-sensitive volume in power MOSFETs has recently been studied in [3] and [4], where front side and back side heavy ion irradiation show that it depends both on the ion range and the Source-Drain bias. The laser Two-Photon Absorption (TPA) technique is known to allow the injection of a high electron-hole pair density, concentrated in a localized volume inside the device [5]- [7]. It has been used to study the in-depth sensitivity of Single Event Transient in linear technology [5], [6] and Single Event Latchup in highly integrated memory [7], [8].…”

A first study of the charge collection volume of vertical power MOSFETs has been given in [9].…”

Improved Fine-Scale Laser Mapping of Component SEE Sensitivity

“…It is necessary to wait an additional interval of time for this vibration to die away in start-stop. Some teams move the laser beam rather than the microchip, but this requires a moving mirror [8], so the acceleration and vibration problems are simply transferred to the mirror translation system.…”

“…For example, French experimenters are currently applying new types of laser scanning of microchips: e.g., in Fig. 2 of [8] an alternative optical setup employs an X-Y scanner that allows fast scanning of small areas using steering mirrors (without 0018-9499/$31.00 © 2012 IEEE moving the device). This paper focuses upon the application of curvilinear scanning trajectories and continuous (piezoelectric) positioning systems and the improvements of laser SEE sensitivity mapping that they facilitate.…”
