WEST LAFAYETTE, Ind. — Scaling up excellence in the semiconductor and microelectronics industry is a key commitment at Purdue University.

A recent success is a project to advance AI hardware: CHEETA, which is funded through the Department of Defense Microelectronics Commons program in collaboration with the Silicon Crossroads Microelectronics Commons Hub.

This roundup comes ahead of Purdue’s third Semiconductor Week, taking place Oct. 28-Nov. 2. The slate of events calls together industry leaders and allows students to engage with professional industry organizations.

Here are more of the latest outcomes in research, workforce development and industry partnerships from Purdue.


RESEARCH BESTS: Applying, enhancing and securing chips for the future

Inspired by the human body, engineer designs chips that could make wearable AI more energy efficient

Purdue engineers are considering how the human body’s nervous system can inform the future of chip design to maximize energy use, which could expand the applications of wearable devices.

Right now, chips in wearable devices can’t access the power of AI without steady internet access because of the energy required. Shreyas Sen and his team are custom-designing chips for a network of wearable devices that can work with “edge devices” to solve more complex problems with AI while using less power — similarly to how a human’s nerves and brain work together.

One potential application: Someone with a heart condition could wear an electrocardiogram that uses AI to more accurately detect irregularities in the heart, even with a bad internet connection.

Keeping today’s hottest electronics cool for users at nanoscale level

Semiconductor-driven machines can only operate as well as we can keep the entire system functioning — including keeping the machine from overheating. Mechanical engineer Amy Marconnet is investigating which tiny materials are best suited to keep tiny microchips from transferring heat in the wrong directions (say, onto your skin) without adding undue weight and cost.

For example, phase changing materials are one option under investigation.

“So you can have the materials be melting while you’re, say, using your VR (virtual reality) goggles,” Marconnet said. “And then when you’re recharging your goggles or overnight, they will solidify, and you can use the device with higher intensity the next day.”

RAPTOR technology secures semiconductors against counterfeit chips

RAPTOR, a patent-pending optical counterfeit detection method, uses deep learning to combat counterfeit chips — a problem that soared during recent chip shortages — while improving on scalability, natural degradation and tampering issues faced by existing anti-counterfeit tactics. Clever girl!

A raptor stands on a microchip branded with the word “RAPTOR.” A hand made of blue circuits points at the chip.
Led by Alexander Kildishev, Purdue University engineers have created RAPTOR, an optical counterfeit detection method. It leverages deep learning to identify adversarial tampering in chips used in semiconductor devices. Their research has been published in the peer-reviewed journal Advanced Photonics.

“The global chip industry is grappling with dual challenges: a profound shortage of new chips and a surge of counterfeit chips valued at $75 billion, introducing substantial risks of malfunction and unwanted surveillance,” Kildishev told Hackster.

SEMICONDUCTORS AND SOCIETY

Inside a semiconductor boot camp with NBC News NOW

Gadi Schwartz, host of NBC’s Stay Tuned NOW, talks the state of semiconductors, beginning with a visit to Purdue’s hands-on “semiconductor boot camp.” In the Summer Training, Awareness, and Readiness for Semiconductors (STARS) program, underclassmen are exposed to the design, manufacture and packaging of microchips.

Reinventing the land-grant university to grow jobs, companies, talent and global competitiveness (Elsevier)

In this post, Purdue President Mung Chiang outlines the responsibilities of modern land-grant universities and how they are positioned to address society’s most pressing problems — now and in the future.

With the accelerated development of the technology and semiconductor industries, demand for both products and services, as well as the highly skilled workforce to support them, is evolving faster than ever.

“We believe it’s key to our mission to serve as an economic growth engine, co-generating what we call the three elements that advance an academic culture that has direct impacts on society: workforce talent, jobs and careers, and knowledge together.”

CAMPUS NEWS: Funding near and partnerships far

Since plans to build a $4 billion AI memory chip production facility in Purdue Research Park were announced this spring, Purdue leaders have been steadily bolstering the university’s relationships with international partners while research faculty have been earning the support of federal funding agencies. Here are some of the headlines from recent months:


Purdue’s growing semiconductor innovation ecosystem is one of four key pillars of Purdue Computes, a comprehensive initiative that also includes positioning the Department of Computer Science as a top 10 national program, becoming a leader in the field of physical artificial intelligence, and advancing quantum science and engineering to create future technologies that enable unparalleled excellence at scale.

About Purdue University

Purdue University is a public research institution demonstrating excellence at scale. Ranked among top 10 public universities and with two colleges in the top four in the United States, Purdue discovers and disseminates knowledge with a quality and at a scale second to none. More than 105,000 students study at Purdue across modalities and locations, including nearly 50,000 in person on the West Lafayette campus. Committed to affordability and accessibility, Purdue’s main campus has frozen tuition 13 years in a row.
