Popis: | A technique for the determination of two-dimensional impurity profiles in silicon using methods for emission computed tomography is presented. Several one-dimensional impurity profiles obtained for different directions through the sample are used to reconstruct the two-dimensional profile. A simulation study of the experiment is described, and effects of various experimental and reconstruction parameters are discussed. Reconstructions of an area of 4 mu m*4 mu m from thirteen one-dimensional measurements, with a resolution of 1000 AA, are numerically possible. > |
