Ion implantation profiles of boron after a BF3 plasma immersion ion implantation in a plasma implanter with a pulsed voltage ion extraction were investigated both experimentally and by means of numerical simulation. Boron profiles for different ion implantation doses in the range 1015 to 1017 cm−2 were measured using the SIMS method. Simulations were performed using a Monte-Carlo based binary-collision...
In this work, the influences of advanced annealing schemes, spike and flash annealing and combinations of them, on the electrical behavior of modern FD SOI MOSFETs have been investigated by numerical simulations. Process simulations have been performed for comparing the two-dimensional diffusion behavior of the dopants under the different annealing schemes. Device simulations have been performed for...
With a novel delineation technique, the increase in dopant concentration due to ions which have been scattered out of a vertical mask edge during ion implantation was demonstrated. The equiconcentration lines show that the implanted concentration near the mask edge is greater than that in the middle of the implantation window. This effect could be simulated qualitatively with a Monte Carlo simulation...
Is order to establish a rigorous test for the various models used to simulate ion implantation in crystalline silicon. we have implanted 17-150 keV boron ions with low doses into ≪111≫ and ≪100≫ silicon in channeling direction. Simulations using the program MARLOWE show that. impact parameter dependent electronic stopping is essential. The binary collision approximation is fully, justified. Moliere...
For the analytical description of doping profiles after ion implantation, good multilayer models are required to describe the implantation through thin layers, e.g. a scattering oxide or non-vertical mask edges. In this paper, benefits and drawbacks of some published models are discussed, and an improvement is suggested. Comparisons with results from Monte Carlo simulations and SIMS measurements are...
For the measurement of dopant concentrations in two dimensions (2d), a delineation technique has been optimized. The method yields up to three dopant equiconcentration lines in one sample. The concentrations of these lines can be changed by modification of the etching conditions. This technique is applied to the investigation of 2d ion implantation profiles.
