Glass core substrates exhibit low CTE and significantly higher rigidity than conventional organic substrates and are therefore regarded as promising core materials for next-generation build-up packages. However, a major challenge lies in the occurrence of SeWaRe defects (delamination in glass), which arise from thermal stresses induced by the mismatch in the coefficients of thermal expansion (CTE) between the glass material and the build-up resin.
To mitigate this issue, we proposed a structure in which the corner regions of each individual piece are formed from resin. However, considering the thermal history during chip mounting, it became evident that the suppression effect was insufficient. Therefore, an edge‑protection material was applied to relieve the stress concentrated at the edges of each individual piece. As a result, it was confirmed that SeWaRe defects could be effectively suppressed even under thermal loading.
Through these efforts, we successfully developed a glass core build-up package substrate incorporating 11 layers of single‑sided copper wiring (22 layers in total).

Co-packaged optics (CPO) is emerging as a key enabler for scaling bandwidth while containing power and cost in next-generation AI and cloud infrastructure. By moving optical engines closer to the switch ASIC and shortening high-speed electrical reaches, CPO can reduce SerDes power, ease signal-integrity constraints, and increase overall front-panel bandwidth density. However, delivering these benefits at volume requires new approaches across package architecture, manufacturing, and system integration.
This presentation reviews the main packaging challenges that must be solved to industrialize CPO, including thermal management and heat spreading near high-power silicon, fiber attach and optical alignment tolerances, photonics/laser integration choices, high-density optical and electrical I/O, substrate and interposer selection, and reliability risks such as warpage, CTE mismatch, and contamination control. Test and rework strategy, yield learning, and supply-chain readiness (materials, assembly, and metrology) are highlighted as practical barriers to adoption.
The talk also outlines opportunities created by CPO packaging innovations—such as modular optical tiles, standardized fiber interfaces, advanced lid/heat-sink concepts, and co-design of electrical, mechanical, and optical domains—to unlock higher radix switches and lower system power. Attendees will leave with a structured view of technology tradeoffs, a roadmap of near-term versus long-term packaging options, and actionable considerations for bringing CPO from prototypes to deployable products.

AI is fueling unprecedented growth and accelerating demand for advanced devices. Its requirements for performance, power, and area scaling are driving memory and logic devices toward 3D architectures.
At the heart of this 3D transformation, processing steps must enable taller, perpendicular structures as well as smaller features. Meeting these requirements calls for new deposition and etch capabilities that did not exist before, leading to breakthroughs needed in areas such as atomic-level deposition and etch (ALD and ALE), high-aspect-ratio processing, dry resist EUV patterning, and the adoption of new materials like molybdenum (Mo). As a result, the transition to 3D devices will drive increased intensity of deposition and etch processing.
This presentation will explore how deposition and etch are critical to unlocking the future of 3D devices, with increasing velocity required to meet the demands of AI-driven innovation.

As the semiconductor industry navigates the challenges of dimensional and functional scaling in the artificial intelligence (AI) era, advanced materials science has emerged as a critical enabler for performance enhancement. Modern AI-centric architectures demand the integration of increasingly complex system-on-chip (SoC) designs with non-traditional material systems.
This work details a high-throughput methodology for the rapid down-selection and optimization of multi-element thin films, ensuring alignment with both physical and electrical key performance indicators (KPIs). Utilizing combinatorial physical vapor deposition (PVD) in conjunction with unit-cell electrical test vehicles, we systematically screen an expansive elemental compositional space to identify optimal candidates. Advanced machine learning (ML) algorithms are integrated into each phase of the development lifecycle—spanning precursor synthesis, process optimization, and heterogeneous integration—to satisfy the rigorous specifications of emerging device applications. The synergy between integrated materials engineering and AI-driven informatics significantly reduces the temporal gap between material discovery and device-level implementation.

As device architectures scale toward the angstrom era, metallization has emerged as one of the most critical bottlenecks to continued improvements in power and performance. Shrinking feature dimensions increase resistance, heighten reliability risks, and add complexity in interconnects and contacts. At these scales, traditional approaches which uniformly affect all wafer surfaces are increasingly ineffective. They rely heavily on lithography to define placement, and struggle to address tighter geometries and growing sensitivity to interfaces. Selective deposition is a solution which enables atomicscale control of where metals grow, placing material only where it is needed, without relying on patterning. It also enables monocrystalline metal growth, eliminating grain boundaries to minimize contact resistance.

This presentation will highlight how Applied Materials’ integrated materials solutions are enabling multiple inflections through area selective metallization. Selective Cobalt Capping technology encapsulates copper interconnects, improving adhesion, suppressing electromigration, and extending copper reliability to advanced nodes. Applied’s Selective Barrier eliminates a highly resistive interface at the interface of interconnect wiring. For contact fill, Applied developed Selective Tungsten (W) as a liner-less gap-fill solution that eliminates traditional liner/barrier layers and enables bottomup, seamfree metal fill. Finally, we introduce Selective Molybdenum (Mo) deposition that carries lowresistivity contact scaling forward as dimensions approach the fundamental scaling limits of W. Applied’s state-of-the-art atomic layer deposition tool for molybdenum delivers bottom-up, single-crystal Mo growth, enabling the next generation of contact scaling.

Cleaning processes originally relied on wet etch based patterning. However, dry etching now performs the majority of the patterning work, so wet etching is no longer needed for most pattern creation steps. Consequently, the focus of cleaning has shifted from patterning to the removal of contaminants. To obtain a clean surface, we must eliminate unwanted contaminants without any side effects such as pattern damage, collapse, material loss, or corrosion.
However, in the current era of 3 D structured devices such as V NAND, GAA, and 3 D DRAM, lateral wet etching is essential for patterning 3 D devices, and the proportion of wet etching in cleaning processes is increasing. Additionally, different kinds of selectivity such as concentration selectivity and area selectivity, have become important, in addition to conventional material selectivity. Sometimes we have to remove a film uniformly even though there are seams and voids. In addition, pattern loading has become a critical factor in lateral removal processes. We must solve these loading issues to achieve better performance and yield.
From time to time we must use more flexible, multi step processes; therefore, premixed chemistry is not enough to meet our purpose. Due to the flexibility of dry (gas phase) cleaning, the portion of dry cleaning has been increasing sharply. Area selectivity has also become another challenge. We must etch without corner rounding or climbing, and we want to perform anisotropic etching.
Conversely, based on the generic clean roadmap, high aspect ratio cleaning and low consumption cleaning will remain continuous challenges. Super critical CO2 drying is a solution for pattern collapse in HAR patterns, yet a dryer that is milder than CO2 but better than conventional IPA dryer technology is still required. In terms of chemical reduction, the puddle process may be a solution, but some side effects related to temperature consistency and cleanliness differences due to fluid dynamics must be resolved before implementation.
