What is ICP (inductively coupled plasma)?
A method that generates a high-density plasma with RF current in a coil. It makes it easy to control plasma density and the energy of ions reaching the wafer independently.
Field: Etching

Field: Etching
An ICP etcher drives RF current through a coil above or around the chamber to induce an electric field that sustains a dense plasma of 10¹¹–10¹² cm⁻³, while a separate RF supply biases the wafer.
Which is a characteristic of inductively coupled plasma (IC…Analyzing the collected liquid by ICP-MS or total-reflection X-ray fluorescence (TXRF) measures whole-wafer metal contamination with sensitivity around 10⁸–10⁹ atoms/cm².
To analyze metal contamination on a wafer surface with high…High-density ICP tools etch mesas for LEDs and lasers and gate recesses for HEMTs, using low ion energies to keep etch damage from degrading performance.
