Diazirine-based photopatterning compounds for polyimides
Innovative diazirine-based compounds enable high-resolution photopatterning of polyimides, facilitating advanced microfabrication and electronics applications. These compounds create strong covalent bonds upon UV exposure, achieving pattern resolutions as fine as 3 um.
Overview
XLYNX Materials Inc. presents advanced diazirine-based compounds designed for the covalent photopatterning of polyimides. These compounds promise a significant leap forward in microfabrication and electronics applications by enabling high-resolution designs on polyimide coatings. The diazirine groups undergo a photochemical reaction under UV light, releasing nitrogen gas and forming reactive carbenes. These carbenes facilitate the creation of strong covalent bonds, allowing precise patterning capabilities.
Technical specifications
- Diazirine Activation: Activated by UV light at 365 nm (i-line), resulting in the release of nitrogen gas and formation of reactive carbenes.
- Photopatterning Resolution: Achieves pattern resolutions as fine as 3 um, with demonstrated photopatternability below 5 um.
- Polyimide Compatibility: Fully soluble in PGMEA and does not interfere with dielectric properties.
- High Heat Resistance: Evaluated for high heat resistance, suitable for final product applications.
- Applications: Ideal for microfabrication, electronics, and semiconductor industries.
Technology readiness level
The technology is currently at TRL 3, with proof-of-concept experiments underway to demonstrate the photopatternability of polyimide resins. Initial tests focus on insertion capabilities and will include DSC and peel tests to validate performance. Collaboration opportunities are available for further development and testing phases.
