摘要

最近,UT-MARLOWE开发并实现了计算效率高的离子注入累积损伤模型4.0和4.1。该模型基于修正的Kinchin-Pease公式,简化了损伤的产生和积累、缺陷的遭遇和非晶化。结果表明,单晶硅中As、B、BF2和P的掺杂谱与实验结果吻合较好。此外,该模型得到的非晶层厚度也与实验测量值吻合较好。基于该损伤模型,开发了一种简单但功能强大且通用的多种植体模拟方法,与实验数据吻合良好。

A computationally efficient ion implantation damage model and its application to multiple implant simulations
A computationally efficient ion implantation cumulative damage model has recently been developed and implemented in UT-MARLOWE Versions 4.0 and 4.1. Based on the modified Kinchin-Pease formula, this model accounts for damage generation and accumulation, defect encounters and amorphization in a simplified way. Good agreement with experimental impurity profiles has been obtained for As, B, BF2 and P implants in single-crystal silicon. In addition, the amorphous layer thicknesses obtained in this model are also in reasonable agreement with experimental measurements. Based on this damage model, a simple but extremely powerful and general method for performing multiple implant simulations has been developed, and very good agreement with experimental data has been obtained.
