Visible light LVP on bulk silicon devices

Conference Proceedings from the International Symposium for Testing and Failure Analysis

Beutler, Joshua; Clement, John J.; Foulk, James W.; Stevens, Jeffrey; Hodges, V.C.; Silverman, Scott; Chivas, Robert

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

We report Pauli blockade in a multielectron silicon metal–oxide–semiconductor double quantum dot with an integrated charge sensor. The current is rectified up to a blockade energy of 0.18 ± 0.03 meV. The blockade energy is analogous to singlet–triplet splitting in a two electron double quantum dot. Built-in imbalances of tunnel rates in the MOS DQD obfuscate some edges of the bias triangles. A method to extract the bias triangles is described, and a numeric rate-equation simulation is used to understand the effect of tunneling imbalances and finite temperature on charge stability (honeycomb) diagram, in particular the identification of missing and shifting edges. A bound on relaxation time of the triplet-like state is also obtained from this measurement.

SOI substrate removal for SEE characterization: Techniques and applications

IEEE Transactions on Nuclear Science

Shaneyfelt, Marty R.; Schwank, James R.; Dodd, Paul E.; Stevens, Jeffrey; Vizkelethy, Gyorgy; Swanson, Scot E.

Techniques for removing the back substrate of SOI devices are described for both packaged devices and devices at the die level. The use of these techniques for microbeam, heavy-ion, and laser testing are illustrated. © 2012 IEEE.
