摘要: 利用二维流体模型和数值计算方法模拟了等离子体浸没离子注入(PⅢ )中,具有圆弧凹槽的平面靶周围的鞘层扩展情况,计算了鞘层扩展过程中的电势分布、离子速度和离子密度变化,获得了沿靶表面的离子入射角度和注入剂量的分布情况,为等离子体浸没离子注入处理复杂形状靶提供了理论基础。

关键词: 等离子体浸没离子注入, 鞘层, 数值模拟

Abstract: The sheath expansion around a planar target with an arc trench during plasma immersion ion implantation(PⅢ) is simulated numerically with a two-dimensional fluid model.The sheath potential,ion velocity and ion density during sheath expanding are calculated.The distribution of ion incident angle and dose along the target surface is presented.It provides the theoretical base for treatment of the targets with complicated shape using plasma immersion ion implantation.

Key words: plasma immersion ion implantation, sheath, numerical simulation
