Ultra-Thin Ceramic Film Based Passive Electronics

This Phase I investigation is focused on demonstration of both capacitors and inductors based on an innovative micron-scale thick high temperature stable dielectric film (Cerablak® UTF) deposited on suitable metal substrates to form MIM capacitors or coating on metal wire to form inductors on an insulating core material. Cerablak® UTF is a transparent ultra-thin film with excellent dielectric characteristics made of aluminophosphate oxide material derived from a patented chemical precursor system. Cerablak® UTF h as excellent adhesion to most metal substrates and also serves as a highly effective diffusion barrier to protect the metal substrate from harsh environments. Previous studies, including recent GEER testing, has confirmed the robust stability and protective nature of Cerablak® UTF films. Phase I effort will include fabrication of suitable prototype specimens of both capacitors and inductors with the objective to downselect suitable MIM designs and identify metal wire based on laboratory scale prolonged high temperature exposure conditions. Suitable specimens will be delivered to NASA for GEER and other testing.

Passive circuit components that can survive in harsh space environments are of critical need to NASA. Power storage via use of stable MIM capacitors is also a critical need for NASA in many of their explorations, including Venus, Mars, and the like.

Non-NASA applications include vehicle engine health monitoring systems for aerospace markets.

This is early/mid-stage (TRL 4) — 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.
