Abstract
Marginal internal leakage in mixed-signal devices at operating mode was isolated using a system evaluation board (SEB) and a highly sensitive infrared detector. Focused ion beam cross-section revealed a thin Ti/TiN metal residue (stringer) over two narrowly spaced metal lines. This is a quick and effective technique in isolating small leaky nets for integrated devices.
