Unity M 85 DRM Dielectric

A dielectric etch tool removes patterned insulating material from a wafer so that circuit features can be opened and transferred into underlying layers during fabrication.

Dielectric etch equipment uses a controlled plasma environment to remove selected dielectric films from exposed areas of a patterned wafer while the masked regions remain protected. Process gases, chamber conditions, and endpoint control are adjusted to shape the etch profile and limit damage to adjacent structures.

In this class of tool, the wafer is loaded into a process chamber, exposed areas are etched, and the process is stopped when the target layer or feature depth is reached. The tool is built to support repeatable dry etching rather than wet chemical removal.

Dielectric etch sits in the pattern transfer part of semiconductor fabrication, after lithography has defined the desired feature pattern in photoresist or another masking layer. It is used before later cleaning, deposition, or planarization steps that complete the layer.

The tool is part of the back-end and interconnect-oriented sequence for opening vias, trenches, and other insulating-layer features on a wafer.

This class of equipment is used for etching insulating films such as silicon dioxide, silicon nitride, and related dielectric materials in integrated-circuit manufacturing. It is commonly applied to feature transfer for contacts, vias, and interlayer structures.
