Research Quality: 50% complete

The SPTS RIE-10 is a deep silicon etching system with dual plasma sources and dual gas inlets. The SPTS RIE-10 achieves an etch rate of 6–10 µm/min and aspect ratio up to 50:1. The SPTS RIE-10 uses fixed RF matching technology for reduced step-process time and controllable side wall roughness below 6 nm.[1][2]

What it is

The SPTS RIE-10 is configured for six-inch wafers and smaller samples.[3][1]

How it works

The SPTS RIE-10 uses dual plasma sources and dual gas inlets.[1][4]

The SPTS RIE-10 includes fixed RF matching technology and a Claritas end point detector.[1][3]

Where it fits in the process flow

The SPTS RIE-10 is suited to fabrication steps that require deep silicon removal, high aspect ratio features, and through-wafer etching.[1][3][2]

Applications

The SPTS RIE-10 is used for silicon etch only.[1][2]

The SPTS RIE-10 is used for micro pillars, nano pillars, micro trenches, nano trenches, via etch, through wafer via etch, and wafer thinning.[1][2]

Frequently asked questions

What types of films can be etched?General reference — not yet source-verified

RIE systems can etch a wide range of films used in device fabrication, including silicon, silicon dioxide, silicon nitride, various metals, and organic materials, depending on the chosen gas chemistry.

Why is reactive ion etching preferred for pattern transfer?General reference — not yet source-verified

The directional ion bombardment in RIE produces anisotropic etch profiles, which preserves critical dimensions during pattern transfer and allows high-fidelity reproduction of small features.
