-Reactive Ion Etching (RIE) uses radio waves and an etchant gas to etch away a sample.  Unlike many chemical methods, RIE is isotrophic making it suitable for etching high resolution lithography.  As an analyst tool it provides a good way to both delayer and even decapsulation chips, although it tends to be much slower than alternative methods.+Mainly this is used for delayering ([[delayer:rie|main article]]) but sometimes used to remove epoxy.
  
-A typical RIE setup (an "asher") has a bottle of gas such as SF6 fed into a quartz tube with a sample in it.  The quartz tube is surrounded by magnetic coils emitting typically 13.56 MHz radio waves.
