Laser SEE testing is an alternative method of testing electronic components and devices that are space bound. Although for accurate measurement of cross section, threshold LET and error rates, particle accelerator testing is preferred, the wait time to get into one of these facilities is quite long and cost per hour is quite high as well. The laser method can be used as a complementary method to identify error modes, disqualify faulty COTS parts and do rapid testing of electronic parts prior to a visit to a particle accelerator SEE testing facility.

Allied Scientific Pro (Gatineau, Canada) has set up a Single Photon Absorption (SPA) test facility which is open to the SEE community in North America. The facility uses a Master Oscillator with Programmable Amplitude Waveform (MOPAW)1 fiber laser with emission at 1030 nm to do the SEE testing. SWIR and visible cameras, high quality illuminator in both visible and Near IR, high precision translation stage along 3 axes, automated scanning, LabView software control, attenuation polarizers, etc. are some of the features of the testing station.

As the first step to validate the performance of the SEE testing station, a few known devices whose SEE behavior were available in literature2 were tested. These included a SRAM and an Op-AMP for which SEU, SEL and SET were detected and hence the performance of the SEE testing station was validated.

The facility is looking forward to testing more complex devices such as FPGAs and Power MOSFETS in near future.

We would like to thank INO (Quebec city, QC, Canada) engineers for providing us with the MOPAW laser and their useful guidance for laser control and selecting the correct laser parameters throughout the course of testing.
