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.

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.
