<h3>Abstract:</h3><h3>High-volume, rapid fabrication of three-dimensional (3D) nano-architected materials and devices is key to deploying next-generation nanotechnologies to solve real-world challenges. Due to the field-of-view limitations of conventional optics, existing 3D nanofabrication techniques face fundamental challenges in throughput, proximity error, and stitching defects on the path to scaling. At LLNL, we have developed a scalable 3D nanofabrication platform that utilizes a metalens-generated focal spots array to massively parallelize two-photon lithography (TPL). Our current system uses over 100,000 high-contrast metalenses to enable the rapid parallel production of complex nanostructures with nanoscale resolution (up to 110 nm) over a 12-cm^2 write field. By programmatically patterning the focal spot array using a spatial light modulator, we further devise an adaptive parallel printing strategy for precise grayscale linewidth modulation and high-throughput production of semi-periodic and fully aperiodic 3D geometries. In this talk, I will share the details of this platform technology that received the R&amp;D 100 Award in 2025. This work represents a paradigm shift for 3D nanolithography from lab-scale prototyping towards wafer-scale production, empowering TPL to be widely adopted at volume in microelectronics, quantum technology, biomedicine, and other fields. I look forward to engaging with the IEEE community to discover suitable use cases in the microelectronics industry, especially for advanced packaging.</h3>Read More: <a href="https://ieee.us6.list-manage.com/track/click?u=4f23d76911d28dcc51bf71bce&amp;id=8c5410e821&amp;e=d63c66b7c5" title="https://ieee.us6.list-manage.com/track/click?u=4f23d76911d28dcc51bf71bce&amp;id=8c5410e821&amp;e=d63c66b7c5" target="_blank" data-msys-clicktrack="0" rel="nofollow noopener noreferrer">3D-printed micro ion trap technology for quantum information applications</a> <a href="https://ieee.us6.list-manage.com/track/click?u=4f23d76911d28dcc51bf71bce&amp;id=b0034ae528&amp;e=d63c66b7c5" title="https://ieee.us6.list-manage.com/track/click?u=4f23d76911d28dcc51bf71bce&amp;id=b0034ae528&amp;e=d63c66b7c5" target="_blank" data-msys-clicktrack="0" rel="nofollow noopener noreferrer">3D polycatenated architected materials</a> <a href="https://ieee.us6.list-manage.com/track/click?u=4f23d76911d28dcc51bf71bce&amp;id=d25b5170c6&amp;e=d63c66b7c5" title="https://ieee.us6.list-manage.com/track/click?u=4f23d76911d28dcc51bf71bce&amp;id=d25b5170c6&amp;e=d63c66b7c5" target="_blank" data-msys-clicktrack="0" rel="nofollow noopener noreferrer">Responsive materials architected in space and time</a> <a href="https://ieee.us6.list-manage.com/track/click?u=4f23d76911d28dcc51bf71bce&amp;id=7984ebe623&amp;e=d63c66b7c5" title="https://ieee.us6.list-manage.com/track/click?u=4f23d76911d28dcc51bf71bce&amp;id=7984ebe623&amp;e=d63c66b7c5" target="_blank" data-msys-clicktrack="0" rel="nofollow noopener noreferrer">Electrochemically reconfigurable architected material</a>
