Reactive ion
WebMERIE, Magnetically Enhanced Reactive Ion Etching, is where a magnetic field is applied in a capacitively coupled plasma etcher. Applied magnetic field enhances the etch rate while reducing the bias voltage simultaneously for a given RF power setting. Webreactive: [adjective] of, relating to, or marked by reaction or reactance.
