Abstract
An apparatus for applying a stress voltage to a device under test includes a stress voltage source, a constant voltage circuit having an input connected to the stress voltage source and an output connected to a control circuit for removing stress when current exceeds a predetermined level which is connected to the device under test. The constant voltage circuit provides a constant stress voltage to the device under test. A monitoring circuit measures the stress voltage applied to the device under test, and measures leakage current through the device under test. A switch has inputs connected to outputs of the monitoring circuit, with the switch being capable of sending a selected output or outputs of the monitoring circuit to a measurement system.
