摘要
A model for the precipitation of oxygen and associated dislocation loops in Czochralski-grown silicon is presented. Beginning with kinetic rate equations describing the growth and dissolution of oxide precipitates, a reduced model based on the moments of the precipitate size distribution is developed and validated against experimental data. The complete model source code is provided. Comparisons with the full, rate equation-based model show that the reduced version is comparably accurate, while requiring significantly less computational power. The formation of dislocation loops due to silicon interstitial ejection during precipitate growth is modeled using a simple, moment-based approach. An analysis of the sensitivity of the oxygen model to parameters is included.
