–  10:50 – 11:05 Neuromorphic Computing Systems for Heteroneneously-Integrated Silicon Photonics LiDAR – Jong Hyeok Yoon  (DGIST)

Dr. Jong Hyeok Yoon is an Associate Professor in the Department of Electrical Engineering and Computer Science (EECS) at DGIST.

His work centers on high-speed integrated circuits and energy-efficient communication systems.

Autonomous vehicles, encompassing unmanned aerial vehicles (UAVs) and unmanned aerial mobility (UAMs), necessitate robust object detection methodologies to facilitate reliable navigation systems. While Time-of-Flight (ToF) LiDAR modules are extensively utilized for object detection in autonomous vehicles, they encounter substantial limitations, including elevated costs, restricted detection angles, and susceptibility to interference from external light sources. Conversely, Frequency-Modulated Continuous Wave (FMCW) solid-state LiDAR modules offer broader detection angles, resilience to interference, and the capability to measure the velocity of nearby objects, rendering them a superior alternative.

In this presentation, I will introduce the KR-EU collaborative project to develop neuromorphic computing systems for heterogeneously-integrated silicon photonics LiDAR. Notably, I will emphasize the role of the Korean consortium, which comprises the following features: 1) The development of FeFET-based compute-in-memory (CIM) accelerators for energy-efficient processing, 2) The design of optimized AI network architectures tailored for real-time semantic segmentation tasks, and 3) The creation of wireline/wireless peripheral circuits to facilitate seamless intra- and inter-agent communication.

– 11:05 – 11:20 Neuromorphic Enhanced Heterogeneously Integrated FMCW LiDAR – Ruud Oldenbeuving (IMEC, NL)

With more than 20 years of experience in laser development and 15+ years of experience in photonic integrated circuit (PIC) development is recognized as one of the Photonics 100, the one hundred most innovative people of 2025 in the worldwide industry by the Electro Optics magazine. He was the first in the world to design, fabricate and characterize a hybridly integrated ultra narrow linewidth laser consisting of InP and SiN, which is nowadays an industry standard. He is consulted by industry leaders, institutes, and universities for his knowledge on this topic and accordingly, considered a thought leader in the field. He has co-authored over 80 papers and several patents. After working at LioniX International and spin-offs thereof for about 13 years, Ruud currently holds a scientific leadership position at imec, focusing on PIC system development.

With self-driving cars quickly emerging as commercial commodity, there is no doubt anymore: autonomous driving vehicles will be the future. This requires 3D sensing of the environment in high resolution, high speed and high accuracy, using complementary and/or redundant measurement methods. Fusing techniques such as radio detection and ranging (RADAR), light detection and ranging (LiDAR) and camera images, seems obvious to achieve this goal. However, the sheer amount of data generated by all of these techniques requires a significant advancement in Neuromorphic edge-computing (in more popular words: Artificial Intelligence), next generation frequency modulated continuous wave (FMCW) LiDAR on low-cost, low power consuming and light weight photonic integrated circuitry (PIC), that can beam-steer and detect without any moving parts, and the integration of electronic integrated circuits (EIC) to drive and read-out and combine all signals.

In the NEHIL project, Korean and European researchers (both academic and industrial) aim to combine Neuromorphic edge-computing with data from a PIC-based FMCW LiDAR using FeFET-based compute-in-memory (CIM) accelerators, to support hybrid SNN/ANN models for semantic segmentation. These systems aim to reduce power consumption and improve the efficiency of the LiDAR system and can be used in autonomous vehicles and other applications. The integration of CIM, neuromorphic computing, FMCW LiDAR and photonic reservoir computing technologies will enable high-resolution, low-power, and cost-effective solutions for real-time data processing and object recognition.

‘Modern information technology accelerated data processing and storage, and scaled up their capacity since the introduction of integrated circuitry in the 1960s. Upon the technology-nodedriven miniaturization, we have witnessed that electronic device structure began to deviate from planar geometry and evolved into three-dimensional space, e.g., trigate FinFET and VNAND for better electrostatic control and massive data storage, respectively.

Following such device structural renovation, this talk will highlight how an emerging class of semiconductors, atomically-thin semiconductors, can be synergistically embedded to function as logic and nonvolatile memory operations in the More-Moore as well as in the More-than Moore domains. More importantly, as an integrated solution, I will introduce vapor-phase deposition (ALD and MOCVD) and a set of nanofabrication strategy tailored for target chalcogenide semiconductors and 3D device geometry. To be specific, I will initially address how our team approach to explore and solve fundamental scientific and engineering challenges in 3D adaptive MOCVD growth of 2D semiconductors and eventually monolithic integration of 2D vertical FETs in the complex device geometries.

Our recent works of hybrid-dual-gated electrochemical and multi-junction tunneling logic transistors will be followed to demonstrate field-controlled bimodal and steep-slope low-power switching, respectively.

In particular, the latter is enabled by phase-centric synthetic strategies where we achieve wafer-scale production of tin selenides (SnSe and SnSe2) in the 2D limit by utilizing a low-temperature MOCVD process. Next, I will present the wafer-scale growth of mono-elemental 2D tellurium (Te) thin films using an annealing-free, low-temperature ALD process. As-deposited Te films exhibit exceptional homogeneity, precise layer controllability, and 100 % step coverage in high aspect ratio nanostructures.

Additionally, we showcase an ALD-Te-based selector device with fast switching time, selectivity and low Vth. Capable of low-temperature processing, I will conclude with the latest research progress toward BEOL-compatible neuromorphic hardware, all based on synthetic chalcogenide thin films.

Epitaxy is a key technique for fabricating single-crystalline thin films on substrates via strong chemical bonding. These covalent bonds extend the crystal symmetry and orientation of the underlying wafer into the epitaxial layer, enabling high-performance semiconductor devices. However, the very nature of these strong bonds makes it difficult to separate the epitaxial layer from the substrate. Given that the epitaxial layer is typically only a few microns thick—compared to several hundred microns for the wafer—the substrate becomes a substantial waste of material and space in high-density microelectronic architectures. Moreover, while epitaxy excels in forming high-quality semiconductors, it poses challenges for heterogeneous integration, which is critical for multifunctional device systems.

In this talk, we introduce novel epitaxial growth strategies that avoid covalent bonding at the interface—namely, van der Waals epitaxy and remote epitaxy.

These methods offer promising pathways for the high-density integration of diverse semiconductor devices. As a demonstration, we present an ultrahigh-resolution full-color display based on a vertically stacked R/G/B pixel architecture.

Using non-covalent epitaxy, we grew red, green, and blue light-emitting diode (LED) epilayers that were subsequently delaminated from their native wafers via simple mechanical exfoliation.

These freestanding LED layers were then vertically stacked and patterned via photolithography to form pixel arrays. As a result, we achieved full-color displays with a pixel density of 5,100 pixels per inch (ppi).

Additionally, we highlight the advantage of remote epitaxy in obtaining excellent crystal quality of the grown layers, further emphasizing its potential in advanced semiconductor integration.

Gaussian distributions are fundamental to probabilistic models, yet their hardware realization remains elusive. Existing solutions based on heterojunction anti-ambipolar transistors suffer from structural asymmetry, inconsistent transport properties, and limited tunability. Here, we introduce a single-material, single-channel split-gate Gaussian-mirroring transistor (SC-SMT) that generates highly symmetric, near-Gaussian transfer curves under reversal gate biasing. Independent gate control enables precise tuning of amplitude, mean, and standard deviation, achieving >99.99% cosine similarity with ideal Gaussian profiles. To validate functionality, we integrated the SC-SMT onto a printed circuit board with real-time current sensing and DAC-based gate control.

This system implements an analog Gaussian Naive Bayes classifier, distinguishing deepfake from authentic voices with 82% accuracy on the ASVspoof2019 dataset. Further, the device exhibits quadratic-order output scaling with dual-gate input, supporting analog vector–vector multiplication. We demonstrate its use in a memristor crossbar array for transformer attention scoring, eliminating the need for matrix projection.

These results establish the SC-SMT as a compact, tunable hardware primitive for real-time probabilistic inference and neuromorphic acceleration.

The development of via-hole-less interconnection technology is important for the successful implementation of vertical integration technology of semiconductor devices, and this interconnection technology requires the introduction of micro-bump conductive ball array technology into RDL technology.

The research team of VEXAN Steel Co., Ltd. is developing this micro-bump conductive ball array bonding technology using micro-particle alignment and transfer technology.

In particular, the development of bump materials and bump formation technology according to the miniaturization of bump size is essential for the development of 3D packaging technology, and the micro-bump array technology of this research team is pursuing a 10μm pitch in the future, so it is considered to be suitable as a bonding solution for the next generation of 3D packaging.

Dr Hee Dae Kim is an Associate Professor of Physics at Jeonbuk National University. He earned his Ph.D in Physics from the University of Oxford and a B.Sc, in Physics from the University of Texas at Austin. He has held research and teaching positions at leading institutions including the University of Oxford (Research Associate/Lecturer), IFW-Dresden in Germany (Postdoctoral Researcher, independant position), Arizona State University (Research Professor), Hokkaido Univeristy in Japan (Assistant Professor), and Northeast Normal in China (Distinguished Professor). He has also served as a visiting professor at Oxford. Research interests: Optical spectroscopy of quantum dots, Surface plasmonbased photonic application, Time-resolved quantum optical analysis.

Recent advances in droplet epitaxy (DE) methods have enable the growth of diverse nanostructures including coupled quantum dots (CQDs). CQDs are regarded as crucial building block for the development of scalable quantum devices, as the coupling between adjacent quantum dots can be controlled both electrically and optically [1-4]. In such systems, the tunneling interaction is typically much weaker in laterally coupled QDs compared to vertically coupled ones, where wavefunction overlap is more likely to occur. Although tunneling-induced coupling is negligible due the relatively large inter-dot distance in laterally configurations, excitons localized in the individual QDs can still interect though dipole-dipole coupling.

This dipole-dipole interaction is primarily mediated by two mechanisms: Foster energy transfer (FRET) and the direct Coulomb interaction. Both mechanisms exhibit a ~1/R12 dependance on the inter-dot distance (~R12), yet their effectiveness is highly sensitive to the spatial configuration of the excitonic dipoles, particularly their orientation and charge distribution. Our findings suggest that excitons and biexctions in laterally coupled QDs exhibit controllable polarization properties, opening the possibility for tunable anisotropic emission through optical manipulation.

Halide perovskite nanocrystals (PNCs) have recently attracted lots of attention due to their excellent opto-electronics properties. Blue-emissive PNCs can be achieved via either size reduction or halide exchange. Low-temperature synthesis or ligand engineering is widely used to reduce the particle size of PNCs, leading to blue emission. However, these methods are limited by high defect density and board FWHM, which causes low PLQY and structural degradation. In this work, the particle siez of CH3NH3PbBR3NCs was reduced by controlling the interaction between ligands and anti-solvents with different dipole moments, enabling the fabrication of highly efficient blue-emissive PNCs. Additionally, halide exchange was employed to achieve blue-emitting PNCs, but high defect density was observed in the chlorine (CI)-exchanged PNCs. To address this issue, a short ligand containing chlorine was applied, which suppressed defect formation and significantly imprived the structural stability of the PNCs, resulting in blue emission at approximately 480nm.
