Advancing Next Generation Microshutter Arrays for Future Astronomical Space-Based Observatories
Completed
TRL 5 (started at 4, targeting 5)
Description
We propose development of a near-unity yield array by perfecting the wafer bonding and back etch processes. We believe this fabrication development is the most critical element to successfully demonstrate a flight-qualified large microshutter array.
Benefits
Large-format NextGen Micro-Shutter Arrays (NGMSA) are a key enabling technology for the LUVEx flagship mission recommended in the Astro20 Decadal Survey. After successfully fielding small-format (128 X 64) NGMSA on-board FORTIS, there was an expressed interest in employing a large-format (736 X 384) NGMSA for the HabEx, CETUS, and LUVOIR concept studies. Specifically, whereas the NGMSA developed for FORTIS could be fabricated on 100mm silicon substrates, the required geometry for the large format necessitated fabrication on 150mm substrates

How to get involved
This is early/mid-stage (TRL 5) — the most realistic path in is NASA SBIR/STTR, which funds small businesses and research institutions to develop technology aligned with NASA's needs (equity-free, phased funding). Check whether a current SBIR/STTR solicitation topic overlaps with this project's technology area, or contact the project directly (above) to ask.
None of these are guaranteed paths for this specific project — TechPort itself doesn't have an "apply" button. Reaching out to the contact(s) above with a specific question is usually the fastest way to find out what's actually open.
