In this paper we demonstrate a method based on ion-beam sputtering to extend the use of the micro four-point probe technique towards the determination of the carrier concentration profile in small (nm-scale) devices. We demonstrate the concept on laser-annealed B implanted Si fins and show that the carrier profile is independent of fin width. The measured profile is Gaussian shaped and suggests a 40% dopant activation compared to the B implant profile as calculated with Stopping and Range of Ions in Matter.
