A 28-year-old postdoctoral researcher from KAIST was recognized for the excellence of his paper at a prestigious international conference on semiconductor design.
The university announced on Monday that Shin Tae-in, a researcher from professor Kim Jeong-ho's lab in the School of Electrical Engineering, was selected as a winner of the Best Paper Award at DesignCon 2025.
This is the second time that Shin has won the Best Paper Award at the conference. In 2022, he was one of the four students from Kim's research lab, who received the award given to only eight recipients.
"Shin's paper was selected from over 100 papers accepted by the conference in late 2024," an official from the research lab said. "His contribution to technological innovation in the field was highly regarded by the judging panel."
Titled "PSIJ-Based Integrated Power Integrity Design for HBM Using Reinforcement Learning: Beyond the Target Impedance," the paper introduces a methodology that optimizes power integrity design for high-bandwidth memory (HBM) packages.
The research lab explained that his approach utilizes power supply noise-induced jitter (PSIJ) as a criterion, incorporating artificial intelligence (AI) to optimize design parameters affecting jitter.
"As next-generation HBM-based package systems continue to advance in speed to support large-scale AI implementations, I aim to establish a foundation for semiconductor signal and power integrity design based on the proposed methodology," Shin said.
The DesignCon is a globally recognized international conference in semiconductor and package design.
Each year, researchers and engineers from leading global tech companies, such as Intel, Nvidia, Google, Micron, Rambus, Texas Instruments, AMD, IBM and ANSYS, as well as students from renowned universities worldwide, participate in this conference held in Silicon Valley.
Among all submitted papers, up to 20 are shortlisted as Best Paper Award nominees.
The authors of these nominated papers must attend the conference in person and deliver a 45-minute oral presentation, after which a strict evaluation process determines the final eight recipients of the Best Paper Award.
