To build a virtual microchip factory, University of Cincinnati doctoral students turned to the real one where they work.
Shailesh Padalkar, Manish Aryal and Anuj Gautam took exacting measurements of machines and workspaces in UC’s Mantei Center clean room to develop a three-dimensional virtual world designed to train new workers for semiconductor manufacturing.
The three students work under the supervision of College of Engineering and Applied Science Professor Sam Anand in UC’s Smart Manufacturing Lab at Digital Futures. The lab focuses on research in virtual and augmented reality for smart or digital manufacturing and training.
“In collaboration with Ron Flenniken, who is the senior clean room engineer, we took measurements of each piece of equipment to build 3D models so it was an exact replica of what we have at UC,” Padalkar said.
Padalkar designed the VR simulator from scratch using Siemens NX 3-D modeling software and the Unreal Engine, software used to make popular games such as Fortnite. He has been working on developing the VR chip manufacturing training modules for the past two years.
UC is using both simulation and in-person instruction in the 8,000-square-foot clean room to train its first group of students in the basics of microchip manufacturing as part of a coalition of 15 colleges and universities called the Ohio Southwest Alliance on Semiconductors and Integrated Scalable Manufacturing.
The goal is to begin preparing students and workers for new high-tech jobs at places like Intel Corp., which is building its first microchip fabrication plant outside Columbus, Ohio.
In 2022, UC organized the higher-education group to train students and workers in semiconductor technology and manufacturing. Intel awarded UC and its partners $3.5 million over three years to provide training.
UC expects to train 1,000 students by the end of 2025.
Marc Cahay, head of UC’s Department of Electrical and Computer Engineering, is planning to expand the microcredentials developed with the support of Intel into a new certificate in semiconductor materials, devices, and circuits, which is expected to appeal to a wide audience of scientists and engineers.
UC played host to a workshop in June to give students a bird’s eye view of the field of semiconductors, covering the fundamentals of chip design and manufacturing. The students received hands-on experience with equipment similar to the kind found at chipmakers such as Intel.
Clean rooms provide a controlled environment that is kept free from contaminants that could affect the sensitive microchips. Before entering, students donned head-to-toe coveralls with hoods, gloves, masks and slip-resistant boots to prevent dust and other contaminants from fouling the sensitive electronics.
Like a squire helping a knight with their armor, a graduate student helped the students with the hoods and hard-to-reach snaps. After learning more about the machines, the students worked with equipment such as a mask aligner used in photolithography.
High school senior Brooklyn Barnes, of Columbus, Ohio, said she is considering following her dad into engineering. Barnes said she was excited about getting to work with actual semiconductor fabrication equipment.
“Once I get out of college, I’ll be ready,” she said.
Tim Agnello, a high school science teacher in Cincinnati, enrolled in the training to learn more about what goes into making microchips.
“Half my job is getting kids excited about science,” he said.
“I’m trained as a geologist, but I teach physical and earth science to eighth-graders. The whole process of getting silicon from quartz and turning it into a microchip is interesting to me,” he said. “The more of this I learn, the more I can relate the science to my students.”
At UC’s Digital Futures building, Agnello got to try virtual reality for the first time. He recognized the benefits of using VR to introduce students to the concepts of microchip manufacturing.
“It was very cool — a little disorienting at first,” he said. “But you press a button and teleport to a different part of the room. And to pick things up — in virtual reality, you could turn gravity off and stack items in space in front of you.”
UC's Anand is no stranger to using simulations in industry. He and his students employ technology such as digital twins that use computer simulations to make real-time adjustments to manufacturing machines in industrial settings.
He said the VR system offers some notable advantages.
“Clean rooms have expensive equipment. You can’t just walk in and use it. And there are very few of them around the country,” he said. “A virtual clean room is convenient. You can do the training or practice your skills almost anywhere. And it provides feedback that shows you where you might need more skills training.”
Anand said if the simulated exercises are fun and engaging, students are more likely to retain what they’ve learned.
UC will be offering more training classes to prepare workers for jobs at microchip manufacturers across the country, particularly Intel, which will need to fill 3,000 positions at its new Ohio plant when it opens in 2027.
