  Abstract

Plasma etching technology has been developed since it is recognized that silicon etching is very crucial in MEMS(Micro Electro Mechanical System) technology. In this study ICP(Inductive Coupled Plasma) technology was used as a new plasma etching to increase ion density without increasing ion energy, and to maintain the etching directions. This plasma etching can be used for many MEMS applications, but it has been used for PCR(Polymerase Chain Reaction) device fabrication. Platen power, Coil power and process pressure were parameters for observing the etching rate changes. Conclusively Platen power 12W, Coil power 500W, etchng/passivation cycle 6/7sec gives the etching rate of 1.2μm/min and sidewall profile of 90±0.7°, exclusively. It was concluded from this study that it was possible to minimize the environmental effect by optimizing the etching process using SF6 gas.
