Numerical Analysis of Characterized Back Interface Traps of SOI Devices by R-G Current

Characterized back interface traps of SOI devices by the Recombination-Generation (R-G) curren: has been analyzed numerically with an advanced semiconductor simulation tool,namely DESSiS-ISE. The basis of the principle for the R-G current's characterizing the back interface traps of SOI lateral p+p-n+ diode has been demonstrated. The dependence of R-G cur rent on interface trap characteristics has been examined, such as the state density, surface recombination velocity and the trap energy level. The R-G current proves to be an effective tool for monitoring the back interface of SOI devices.
