News from the U.C. Santa Barbara Nanofabrication Facility.

Oxford PlasmaPro ICP Etcher installed

We have a new ICP etcher in Bay 2: Oxford_ICP_Etcher_(PlasmaPro_100_Cobra)

The tool has been qualified for InP Ridge and InGaAsP Grating etches, and is intended for III-V etching in general (GaAs, GaN, GaSb etc.)

In addition, the tool is capable of Atomic Layer Etching on various materials. Contact the supervisor for training. // John d 11:27, 29 September 2021 (PDT)

SiO2 etching, High-Aspect Ratio

Dr. Bill Mitchell recently published an article detailing high-aspect ratio SiO2 etching (JVST-A, May 2021) in the Plasma-Therm Fluorine ICP etcher, using a novel Ruthenium Hard Mask.

Ruthenium can be deposited using the Oxford ALD or AJA Sputter and etched in one of the Panasonic ICP's.

You can find a full process flow at the FL-ICP's Recipe Page, in this case using a Sputtered Ru hard mask and I-line stepper lithography. // John d 08:05, 27 May 2021 (PDT)

Wafer Polisher available

We have added an Allied Wafer Polish tool to our equipment list. Contact Brian Lingg for more information. // John d 16:49, 10 May 2021 (PDT)

Digital Microscope: Olympus DSX-1000

You'll see a new digital microscope in Bay 4/Metrology, that's our new Olympus DSX-1000. We are currently developing procedures, keep an eye out for training emails. // John d 13:49, 8 April 2021 (PDT)

Raith Velion: FIB/SEM Installation

We have installed a new state-of-the-art focused ion beam/electron beam tool in Bay 1. The Raith Velion enables synchronized interferometric stage, Focused-ion Beam Lithography with ~10nm features or less, live SEM during writing, and Electron-Beam Lithography.

Learn more about the tool's capabilities at the Raith website:

Tool qualification is currently underway. Dr. Dan Read is be the resident expert on this new tool.

-=== S-Cubed Spin/Coat/Dev Station Installation ===
-We are currently in the process of installing a Cube system for automated Spin Coating, Baking, Developing and Edge-Bead Removal on 4-inch and 6-inch wafers.  Initially this tool will be solely purposed for Staff and the use of the sponsor, primarily for [[Stepper 3 (ASML DUV)|ASML DUV Stepper]] wafer prep. As procedures are developed, the system will be opened up for use by all ASML Stepper users, and may eventually be opened for I-Line stepper use as well.

The system complements the [[Laser_Scanning_Confocal_M-scope_(Olympus_LEXT)|LEXT Confocal Microscope]] and [[Atomic Force Microscope (Bruker ICON)|AFM]], by providing large-area profiles (~5-10mm square) with nanometer-level height resolution, and possibly a fast surface roughness measurement.  See the [[White-Light/Phase-Shift_Interference_Profilometer_(Filmetrics_Profilm3D)|Profilm3D Wiki Page]] for more info on the capabilities and techniques.
