2024-12-20 to 2025-01-02: Reduced Holiday Operations

Dear Birck Research Community,

The Purdue winter recess begins effective Friday afternoon December 20th and concludes Thursday morning, January 2. The university is officially closed during this time. As we have done in past years, the Birck Nanotechnology Center will remain available for research but will be unstaffed and hazardous gasses will be unavailable. Lab work may otherwise proceed, though any fume hood work must be done with someone else present in the same laboratory or cleanroom bay (the "buddy" system). Click the link above to get more detail about equipment conditions and rules.

Refer to the Material and Process Compatibility page for information on materials compatible with this tool.
Equipment Status: Set as UP, PROBLEM, or DOWN, and report the issue date (MM/DD) and a brief description. Italicized fields will be filled in by BNC Staff in response to issues. See Problem Reporting Guide for more info.

iLab Name: Axic

iLab Kiosk: BRK Growth Core
FIC: Shared
Owner: R ich Hosler
Location: Cleanroom - R Bay
Maximum Wafer Size: 8"/200 mm

Notes: Axic SiO2 dep rates are a little below stated recipe values at the moment. For example the 40nm/min dep recipe is putting down about 32nm/min. I'm investigating this as time allows but just be forewarned that this is the current state.

Questions & Troubleshooting

What kind of quality can I expect from deposited oxide?
Below is an example of deposited PECVD oxide under AFM. Note that this was taken when the tool was initially installed, and is for illustrative purposes only:
