Parameter Investigation of Nano-Sized Etching in an ICP Silicon Etching System

摘要

The effect of process parameters on the performance of silicon nano-sized etching in an Inductive-Coupled-Plasma Reactive-Ion-Etching (ICP-RIE) system is studied by the Taguchi experimental method. The Standard L9 orthogonal array is considered to evaluate the parameter effect and to obtain the optimum conditions. A total of 9 parameter settings are conducted to investigate the four parameters with three levels for each. The four parameters include the substrate temperature, bias power, gas cycle time and C
