Standard Test Method for Separating an Ionizing Radiation-Induced MOSFET Threshold Voltage Shift Into Components Due to Oxide Trapped Holes and Interface States Using the Subthreshold Current-Voltage Characteristics
|Publication Date:||10 May 1998|
|ICS Code (Transistors):||31.080.30|
1.1 This test method covers the use of the subthreshold charge separation technique for analysis of ionizing radiation degradation of a gate dielectric in a metal-oxide-semicond
1.2 Procedures are given for measuring the MOSFET subthreshold current-voltage characteristics and for the calculation of results.
1.3 The application of this test method requires the MOSFET to have a substrate (body) contact. MOSFETs on silicon-on-insulator
1.4 Both pre- and post-irradiation MOSFET subthreshold source or drain curves must follow an exponential dependence on gate voltage for a minimum of two decades of current.
1.5 This standard does not purport to address all of the safety problems, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
