An ultra-short pulse laser process is presented that is based on a photon-induced phonon excitation process for low-temperature nano-surface modification of silicon. The present methodology is based on the concept that the energy required for re-crystallization and activation of the implanted dopants is supplied to the dopant layer via a nonequilibrium adiabatic process induced by ultra-short pulse laser irradiation at room temperature. An ultra-short pulse laser beam with a pulse duration of ~ 100 femtoseconds has been used in the present work for the investigation of surface excitation features via pump-probe reflectivity measurements and for demonstrations of room-temperature re-crystallization and activation of ion-implanted silicon substrates.

Abstract Ultra-short pulse laser ablation is applied to IC backside sample preparation. It is contact-less, non-thermal, precise and can ablate the various types of material present in IC packages. This study concerns the optimization of ultra-short pulse laser ablation for silicon thinning. Uncontrolled silicon roughness and poor uniformity of the laser thinned cavity needed to be tackled. Special care is taken to minimize the silicon RMS roughness to less than 1µm. Application to sample preparation of 256Mbit devices is presented.
