Inside the buzzing, meticulously managed atmosphere of Cornell’s NanoScale Science and Technology Facility (CNF), Nandan Reddy Muthangi is aware of that even the slightest miscalculation can undo hours of labor. Clad in cleanroom gear, he rigorously calibrates the settings on a 3D lithography system and begins etching microscopic constructions – work that might assist enhance the reliability of microchip manufacturing that can energy future applied sciences.
A Master of Engineering (M.Eng.) scholar within the Semiconductor and Quantum Materials Pathway on the Cornell Duffield College of Engineering, Muthangi is advancing new strategies for constructing semiconductor check chips for programs used to make sure reliability in manufacturing. Most semiconductor units corresponding to microchips are made by way of tightly managed, microscopic steps. Even the smallest defect can influence efficiency or trigger failure, making exact metrology applied sciences important for catching points early and guiding the manufacturing course of.
Through his M.Eng. diploma program, Muthangi partnered with the corporate Xallent to advance this strategy by growing high-resolution check chips able to detecting smaller variations than typical tools. By enhancing how exactly measurements might be made, the chips will assist producers produce extra dependable units at scale.
Inside CNF – a state-of-the-art nanofabrication facility in Duffield Hall, the place researchers engineer supplies and units on the nanoscale – Muthangi works by way of the total fabrication course of. He begins with lithography, patterning microscopic constructions onto substrates utilizing tools like contact aligners, adopted by metallic deposition and etching steps to construct and refine the options. He then evaluates the outcomes, measuring thickness, floor high quality and structural integrity. It’s a posh workflow that requires fixed iteration.
“Some days I’m in the cleanroom fabricating, and other days I’m reading research papers and trying to understand why something didn’t work,” Muthangi stated. “If the output is different than what I expected, I switch gears and try to explore a new way.”
Designing, constructing and testing units is on the coronary heart of Muthangi’s work and the partnerships that gas Cornell’s M.Eng. program. Through this collaboration, Xallent – a Cornell-spinoff firm now primarily based in Albany, New York, that develops high-precision semiconductor testing tools – leverages Muthangi’s knowledge and Cornell’s superior fabrication sources to refine its engineering approaches. At the identical time, Muthangi positive factors worthwhile expertise on a mission with tangible business influence.
“That blend of deep technical knowledge and hands-on practice is central to our Materials Science and Engineering M.Eng. program,” stated Kintu Early, director of this system and a professor of apply. “The projects that our students work on, whether with industry or faculty, help prepare them for careers in some of the most critical and rapidly evolving industries.”
For Muthangi, the expertise has been transformative. Coming from a pc science background, he was unfamiliar to the cleanroom atmosphere. But steering from Cornell school and workers helped him construct the data and technical experience.
Beyond the technical abilities, the M.Eng. program has impressed Muthangi’s profession targets. After graduating, he hopes to work in semiconductor course of or manufacturing and, long run, is concerned about combining that data with synthetic intelligence to reimagine how microchip manufacturing is managed.
“If you look around, almost everything relies on a chip – electronics, medical devices, transportation,” Muthangi stated. “As these devices continue to shrink, it’s important we continue to improve how we test and manufacture them. I want to be part of that.”
