Abstract
A method for IDDQ testing to detect defects in a semiconductor device in the presence of a high background leakage current. In one embodiment at least a portion of a semiconductor device is biased and a first quiescent current measurement is taken. The portion of the semiconductor device that was biased is then unbiased and a second quiescent current measurement is taken. The first and second quiescent currents are then compared to determine if a defect exists in that portion of the semiconductor device.
