What it is
How it works
General reference — not yet source-verifiedA dielectric dry etch tool removes selected dielectric material from a wafer using a plasma-based process rather than liquid chemistry. The wafer is exposed to a controlled reactive environment so material is etched in patterned regions while masked regions remain protected.
Dry etch equipment of this class is typically used in a vacuum process chamber with gas flows, plasma generation, and endpoint control to shape feature profiles and transfer patterns into insulating films.
Where it fits in the process flow
General reference — not yet source-verifiedDielectric etch sits in the pattern-transfer portion of semiconductor fabrication. It follows pattern definition on the wafer and precedes later cleaning, inspection, and subsequent integration steps.
This type of tool is used when circuit patterns must be opened or transferred into dielectric layers such as interlayer insulating films or hardmask-related structures.
