Telius SP 305 SCCM Dielectric

Dielectric etch tools remove insulating films from patterned wafers so later process steps can define structures or open contact features. This class of equipment is part of the dry etch segment of wafer fabrication.

A dielectric etch system uses a controlled plasma environment to remove selected dielectric material from exposed areas of a wafer while leaving masked regions in place. The process is directional compared with wet removal methods, which helps preserve patterned feature geometry.

Such tools typically combine a process chamber, gas delivery, vacuum handling, and endpoint control so etch rate and selectivity can be managed during production. The exact chamber architecture and recipe set are model-specific and are not given here.

Dielectric etch sits after patterning of the wafer surface and before downstream steps that depend on openings through insulating films. It is used when a patterned mask must be transferred into a dielectric layer.

In a fabrication flow, this class of tool is used in dry etch modules rather than deposition or lithography modules. It is part of the sequence that turns a resist pattern into a physical opening or trench in the film stack.

Dielectric etch tools are used for insulating films such as oxide or similar interlayer dielectrics in integrated circuit fabrication. They are selected when the process requires removal of a dielectric layer with patterned fidelity.
