摘要
Plasma immersion ion implantation (PIII) is a technique for surface modification of three dimensional objects where the spatial dose distribution and homogeneity is a priori unknown. Here we present model calculations for trenches. determining the retained dose, the angle of incidence and the depth profiles. In the trenches, especially in the side walls, a reduced dose is obtained as the plasma sheath expands out of the trench during the pulse. A reduction of the pulse rise time from 2 to 0.1 mu s results in an increase of the ion range of up to 100%. (C) 1999 Elsevier Science B.V. All rights reserved.
