News from the U.C. Santa Barbara Nanofabrication Facility.
SiO2 etching, High-Aspect Ratio
Wafer Polisher available
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:
- Raith Products: Velion.
- VIDEO: Synchronized FIB beam + Laser Interferometric Stage write, with live SEM
Tool qualification is currently underway. Dr. Dan Read is be the resident expert on this new tool.

Heidelberg MLA-150: Delivery Scheduled for Sept.
Our Heidelberg Maskless Aligner (MLA150) will be installed the week of September 21st 2020! This tool enables flexible I-Line lithography, in which a user can align to arbitrary features (eg. 2D materials, quantum dots), upload a CAD file to write a pattern without ordering a mask plate, grey-scale lithography and continuous auto-focus on non-planar substrates.
Learn more about the tool at the Heidelberg Instruments website:

TechTalk: Dr. Renan Moreira & Grégoire Coiffard
12n: Dr. Renan Moreira, ULL Technologies: “Ultra-low loss photonic integrated circuits based on Si3N4 waveguides”
1245pm: Grégoire Coiffard, Mazin Group, Physics Dept. UCSB, “The fabrication of 20,000 pixel kinetic inductance detector arrays for near-IR to visible astronomy” // John d 11:03, 5 December 2019 (PDT)
New Plasma Asher Installation
A new YES EcoClean Plasma Strip/Descum System is being installed, for controlled photoresist etching & residue stripping. We will make an announcement when the system has been qualified and is ready for use. // John d 11:03, 7 August 2019 (PDT)
Rapid Thermal Annealer Installed
We are installing and qualifying a new SSI Solaris 150 Rapid Thermal Processor. We will make an announcement when the system is ready and trainings are scheduled. See the SSI RTP Wiki Page here. // John d 12:03, 28 May 2019 (PDT)
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 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. // John d 12:10, 20 February 2019 (PST)
Filmetrics Optical Measurement Systems
A Filmetrics F10-RT for optical reflection/transmission spectra, and a Filmetrics F50 thin-film wafer-mapping system have been installed. Contact Ning Cao for more info. // John d 15:24, 12 December 2018 (PST)
KLA Tencor Profilometer Installed
Laser Endpoint Monitors
We've installed new Intellemetrics LEP500 Laser Endpoint Detection monitoring on the DSEiii & ICP#2 & ICP#1 etchers. This allows you to terminate your etch at a calibrated/modeled distance into a layer, and removes the need to calibrate etch rates for most processes. // John d 09:26, 17 July 2018 (PDT)
Metal Processes on the Atomic Layer Deposition
We now have Ruthenium (Ru) and Platinum (Pt) metal depositions developed on the Oxford FlexAL ALD tool. See the Atomic Layer Deposition: Recipes page or contact Bill Mitchell for more information. // Posted: 16:07, 01 June 2017 (PST)
New Deep Silicon Etcher Online
A new Plasma-Therm Versaline DSE III DRIE etcher has been qualified for bosch etch and single-step etches, and is available for use. The new tool features much higher silicon etch rates, improved uniformity, and allows for photoresist up to the edges of the wafer. An Intellemetrics LEP500 laser end point monitor has also been installed on the system. // Posted: 22:16, 27 November 2017 (PST)
