Abstract :
This work presents a simplified procedure to obtain the ionization profile from SRIM2010 and the Katz radial dose model applied to oxygen ions with kinetic energy from 12 to 18 MeV. Device simulation of Single Event Upsets needs LET(z) and w(z) (linear energy transfer and lateral radius) as inputs. TCAD simulations with the calculated ionization profile of a digital test chip predicts a SEU Threshold. That threshold is experimentally confirmed using the ion microprobe of the Tandem Van de Graaf accelerator at the CNA facility (Spain), validating the ionization model.
