At-speed, internal-node, backside laser-probing of flip-chip ICs using amplitude and phase-sensitive detection modes is characterized. Results show that phase-sensitive detection gives consistently higher signal quality, is less sensitive to probing conditions such as probe placement and sample drift, and can acquire waveforms at nodes difficult to probe using amplitude detection.
