Visible light LVP on ultra-thinned substrates

Beutler, Joshua; Clement, John J.; Miller, Mary A.; Stevens, Jeffrey S.; Cole, Edward I.

Visible light laser voltage probing (LVP) for improved backside optical spatial resolution is demonstrated on ultra-thinned samples. A prototype system for data acquisition, a method to produce ultra-thinned SOI samples, and LVP signal, imaging, and waveform acquisition are described on early and advanced SOI technology nodes. Spatial resolution and signal comparison with conventional, infrared LVP analysis is discussed.
