|Title:||IonRock: software for solving strain gradients of ion-implanted semiconductors by X-ray diffraction measurements and evolutionary programming|
|Abstract:||We present a program that uses an optimization algorithm to fit rocking curves of ion-implanted semiconductors. This is an inverse problem that cannot be solved by simple methods. However, using recursion formulae for rocking curve calculations and a model of ion distribution after implantation, it is possible to fit experimental data with a general-purpose optimization method. In our case, we use a modified version of the genetic algorithm, which has been shown to be a good technique for this problem. The program also calculates rocking curves for a given ion profile, such as those generated by ion implantation simulation programs. (C) 2004 Elsevier B.V. All rights reserved.|
