Abstract By inducing two-photon absorption within the active layer of a 28nm test chip, we demonstrate nonlinear laser-assisted device alteration and single-event upsets by temporarily perturbing the timing characteristics of sensitive transistors. Individual qualitative and quantitative evaluations are presented for both techniques, with lateral resolutions demonstrated with sub-100nm performance. A simplistic signal response rate comparison analysis of these two technologies is also presented.

Abstract By implementing two-photon optical-beam-induced current microscopy using a solid-immersion lens, imaging inside a silicon flip chip is reported with 166nm lateral resolution and an axial resolution capable of resolving features only 100nm in height.
