The Mattson Aspen II ICP LE is an inductively coupled plasma low-energy etch system designed for semiconductor wafer processing.
Inductively coupled plasma etchers generate a high-density plasma using a radio-frequency coil wrapped around a dielectric chamber, producing a reactive ion etch with independent control of ion energy.
Etch systems of this class remove material from defined areas on the wafer to create features such as contact holes, vias, or trenches, and are preceded by lithography and followed by cleaning and inspection.
