AMS 200 SE
The Alcatel AMS 200 SE is a Deep Reactive Ion Etching (DRIE) system for Silicon (Si) and Silicon-on-Insulator (SOI) wafers. The Alcatel AMS 200 SE uses an Inductively Coupled Plasma (ICP) source with RF power up to 3 kW and offers both RF and pulsed LF wafer biasing for flexible etching of dielectrics and silicon.[1]

What it is
General reference — not yet source-verifiedDeep reactive ion etchers are plasma dry-etch tools used to transfer patterned features into substrates by combining chemical reaction and ion-assisted removal. Deep reactive ion etchers are typically used when a process needs anisotropic profiles, significant etch depth, or high aspect ratio structures in materials such as silicon.
How it works
The Alcatel AMS 200 SE has a loadlock and transfer arm designed for transfer between the loadlock and the processing chamber in 40 s. The Alcatel AMS 200 SE includes end-point detection based on laser interferometry through a top viewport. The Alcatel AMS 200 SE monitors a 670 nm laser signal for transparent-film etch tracking and buried-oxide detection during SOI etching. The Alcatel AMS 200 SE has a camera and laser mounted on an X/Y stage for spot positioning on the wafer. The Alcatel AMS 200 SE has 7 mass flow controllers for 6 gases: SF6, C4F8, CH4, O2, Ar, and He. The Alcatel AMS 200 SE allows SF6 and C4F8 to be used in pulsed mode for Bosch processing.[1][2]
Where it fits in the process flow
The Alcatel AMS 200 SE supports three process families: silicon etching with a pulsed process, silicon etching with a continuous process, and dielectric etching. The pulsed silicon process corresponds to the Bosch process. The Alcatel AMS 200 SE is used after lithographic patterning of a mask layer and before mask removal and cleaning steps.[1][2]
Applications
The Alcatel AMS 200 SE is intended for silicon and silicon-on-insulator wafer etching. The Alcatel AMS 200 SE also supports dielectric etching. The Alcatel AMS 200 SE is not microelectronic compatible. The Alcatel AMS 200 SE can load borosilicate and sodalime wafers when they have a backside conductive layer. Fused silica, Pyrex, and float glass wafers require a conductive backside layer because of the electrostatic clamping chuck.[1][2]

Why won't it start?
Documented failure modes, common issues, and field considerations.
- The equipment is not microelectronic compatible.
- Borosilicate (Pyrex) and sodalime (floatglass) wafers can be loaded only with a backside conductive layer.
- For fused silica, Pyrex, and float glass wafers, a conductive backside layer is required because of the electrostatic clamping chuck.
