The broader impact/commercial potential of this Partnerships for Innovation - Technology Translation (PFI-TT) project is to enable better cooling for more efficient and powerful computing. This technology development and commercialization project will investigate the potential benefit of 3D printing metal fins directly onto silicon to enable a 10X improvement in cooling compared to standard existing technologies. This technology may enable faster and higher power computing, especially for supercomputers conducting high demand processes, such as training artificial intelligence systems. The research objective is to demonstrate a performance benefit resulting from the optimization of the printing process, mechanical bonding/reliability, and the heat sink design. The education objective is to train a postdoctoral and student team in the essentials of entrepreneurship and leadership through industry mentorship and participation in Binghamton University’s XCEED and regional I-Corps program. Participation will be broadened by inclusion of an LSAMP summer student in the research, and having the student and postdoc team lead a seminar explaining their innovation and entrepreneurial quest at our campus LSAMP’s seminar series. The proposed project focuses on translating research on laser printing a molten metal alloy, called Sn3Ag4Ti, on a silicon substrate into a minimum viable product for demonstration to potential development and strategic partners. The process includes depositing a thin powder layer of Sn3Ag4Ti onto silicon and exposing the areas where cooling fins are desired to laser heating. Subsequent layers of copper are then deposited onto this layer to form high-aspect ratio cooling fins using selective laser melting. The rapid laser heating forms thin silicide and intermetallic films at the interface. The manufacture of the entire fin assembly using selective laser melting will be researched, specifically how to deposit high thermal conductivity copper metal onto the Sn3Ag4Ti layer. We will also measure the interfacial mechanical properties and thermal cyclability of the device, which are critical to electronic packaging reliability. The design of the heat sink at high heat fluxes, expected in the next generation of packages, will be optimized using neural network techniques. Our research will solve key translational challenges by refining the processing method, demonstrating long-term mechanical reliability, and optimizing the printed heat sink for minimal thermal resistance at high heat fluxes.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

这一创新-技术转化伙伴关系(PFI-TT)项目的更广泛影响/商业潜力是实现更好的冷却，以实现更高效和更强大的计算。这个技术开发和商业化项目将调查3D打印金属翅片直接在硅上的潜在好处，使冷却能力比标准现有技术提高10倍。这项技术可能会使计算速度更快、功率更高，特别是对于执行高要求过程的超级计算机，例如训练人工智能系统。研究目标是证明打印工艺、机械粘合/可靠性和散热片设计的优化带来的性能好处。教育目标是通过行业指导和参与宾厄姆顿大学的Xceed和地区i-Corps计划，培训一支博士后和学生团队，掌握创业和领导力的基本要素。通过将一名LSAMP暑期学生纳入研究，并让学生和博士后团队领导一个研讨会，在我们校园LSAMP的研讨会系列中解释他们的创新和创业追求，将扩大参与范围。拟议的项目重点是将在硅衬底上激光打印一种名为Sn3Ag4Ti的熔融金属合金的研究转化为最低限度可行的产品，以便向潜在的开发和战略合作伙伴进行示范。该工艺包括在硅上沉积一层薄薄的Sn3Ag4Ti粉末层，并将需要冷却翅片的区域暴露在激光加热下。然后，使用选择性激光熔化将随后的铜层沉积到该层上，以形成高深宽比的散热片。快速的激光加热在界面处形成了薄的硅化物和金属间化合物薄膜。将研究利用选择性激光熔化制造整个翅片组件，特别是如何在Sn3Ag4Ti层上沉积高导热金属铜。我们还将测量器件的界面机械性能和热循环性能，这对电子封装的可靠性至关重要。预计在下一代封装中，高热流密度散热器的设计将使用神经网络技术进行优化。我们的研究将通过改进加工方法、证明长期机械可靠性和优化印刷散热器以在高热流密度下将热阻降至最低来解决关键的翻译挑战。该奖项反映了NSF的法定使命，并通过使用基金会的智力优势和更广泛的影响审查标准进行评估，被认为值得支持。
