MXenes are an emerging class of highly conductive, two dimensional materials that combine metallic performance with solution based processing. These properties position MXenes as promising candidates for next generation technologies in microelectronics, sensing, and flexible devices. Despite their potential, widespread adoption has been limited by the lack of a practical and scalable method that can pattern MXene films into high quality microelectrodes with sub micron precision.

Unmet Need

As device geometries continue to shrink, industry requires materials that can be patterned with increasing accuracy, ideally below one micron, while avoiding costly or hazardous fabrication routes. Existing MXene patterning techniques, including plasma etching and lift off processing, face significant challenges related to equipment expense, pattern fidelity, film uniformity, and compatibility with common substrates. A simpler, more scalable solution is needed to enable broader integration of MXene based components.

Our Technology

We developed a highly selective wet etching process that allows clean and precise patterning of MXene thin films using standard photolithography and widely available wet chemistry materials. This gentle approach preserves the intrinsic electrical properties of the films and produces well defined microelectrodes suitable for wafer scale fabrication. The method provides high resolution, excellent uniformity, low operational cost, and full compatibility with silicon, glass, and other widely used substrates. These advantages make integration of MXenes into advanced device architectures both straightforward and commercially relevant.

Market Opportunity

The technology serves a broad range of sectors that require finely patterned conductive materials. In microelectronics and semiconductor manufacturing, it enables the fabrication of advanced interconnects and electrodes, including those that require low temperature processing or compatibility with sensitive substrates. In sensing and photodetection, the ability to define sharp MXene features supports the development of high performance optical, chemical, and electronic sensors. The method is also well suited for flexible, wearable, and large area electronic systems, where lightweight conductive patterns are essential. Additional opportunities arise in compact energy storage and energy conversion devices, such as micro supercapacitors and on chip power units. These application domains collectively represent a significant and expanding demand for scalable MXene patterning technologies.
