Nordson MARCH introduces its Plasma Confinement Ring for wafer processing and wafer fan-out applications. The ring concentrates and focuses the plasma directly over the wafer to speed up the etching process, provide uniform plasma coverage, and to isolate the plasma on the wafer itself rather than the area around or below it. Process temperatures can be kept low because the ring increases etch rate capability without the need to increase the electrode temperature or add bias to the chuck.
