Abstract

The dry etching technologies reactive ion etching (RIE) and ion beam etching (IBE) have both been shown to cause a damaged layer at silicon surfaces. It has been demonstrated that this damage can be annealed out or, alternatively, it can be passivated with low energy hydrogen implants from a Kaufman ion source. This study further explores the hydrogen passivation approach by focusing on the effect of hydrogen implantation on damage caused by argon ion beam etching. The lighter hydrogen ions are actually shown ta cause more extensive damage than the heavier argon ions. However, by using low-energy hydrogen implants all damage, that present from the Ar and that generated during the hydrogen implant, can be passivated.
