Inductively Coupled Plasma Reactive Ion Etch (II)
Introduction
An inductively coupled plasma (ICP) reactive ion etch enables anisotropic etching, passivation and isotropic etching processes. Suspension structures can be formed by a fabrication process, dry SCREAM. The success of this fabrication process has been found by demonstrating a variety of movable actuators.
