Radiation Hardness Assurance

Combination of Heavy Ion, Laser and Proton Irradiation for SEE Qualification Test, Advantages and Limitations


Vasily S. Anashin, Aleksandr E. Koziukov


One of the most actual goal during radiation experiments is getting full information (more data) from tests with beam time and cost reducing. Sometimes one or another testing method is limited by impossibility of DUT de-encapsulation, impact penetration requirement, heavy ion LET discrete values [1] and small equivalent LET values of secondary particles from proton. The most effective approach for wide device parameterization is combination of different facility using (laser, heavy ion and proton beams). Each of them has a lot of advantages and limitations such as similar physical nature for ions and protons, high penetration ability and small size of a beam for protons, milli- and micro- size of laser spot, precise and monotonous adjusting of laser energy (having more equivalent LET values) and possibility of scanning for laser.

The consequence of test facilities choice is depended on type of the test (evaluation or validation). During validation test more rational is staring from proton facility for potentially susceptible devices rejection (without solving the problems with possibility de-encapsulation). Next heavy ion test is carried out (characterization of hardened DUT is performed) and in case of bad results an additional investigation on laser facility is carried out and allowed to clarify LET threshold values and localized sensitive to SEL regions [2], performing SEL stress test in every founded region. During evaluation test the main facility is based on heavy ion accelerator [3] while laser facility and proton cyclotron play a role of supporting tools
