Dual Stage Voltage Ramp Stress Test for Gate Dielectrics

A testing system for testing the integrity of a gate dielectric includes a testing apparatus, the testing apparatus including a test probe configured to contact and provide a voltage across the gate dielectric and to measure a current passing through the gate dielectric. The testing system also incl...

Zusammenfassung:A testing system for testing the integrity of a gate dielectric includes a testing apparatus, the testing apparatus including a test probe configured to contact and provide a voltage across the gate dielectric and to measure a current passing through the gate dielectric. The testing system also includes a computing device coupled to the testing apparatus an causing the testing apparatus to apply a constant voltage as part of a first test to the gate dielectric through the test probe until a first predetermined current is measured passing through the gate dielectric and to apply an increasing voltage to the gate dielectric after the first predetermined current is measured.
