Two drivers carry the strongest influence on 3D IC and 2.5D IC packaging demand during the forecast period.

AI Accelerators and HBM Are Driving 3D IC and 2.5D IC Packaging Demand

AI accelerators and high-bandwidth memory are the strongest drivers of 3D IC and 2.5D IC packaging demand. Graphics processors and custom AI chips need huge memory bandwidth, which can only be delivered by placing stacked memory right next to the processor.

The mechanism is advanced packaging integration. In 2.5D designs, processors and HBM stacks sit side by side on a silicon interposer with thousands of fine connections. HBM itself is a 3D stack of memory dies connected by through-silicon vias. TSMC’s CoWoS technology is used for many leading AI chips, and supply has been tight. Reports in June 2026 indicated the CoWoS supply-demand gap was expected to narrow from about 20% to 10% by the end of 2026 as new capacity came online. CoWoS wafer prices were reported near US$ 10,000 per wafer, showing the high value of these packages.

Chiplet Architectures Are Expanding 3D IC and 2.5D IC Packaging Use

Chiplet architectures are expanding the use of 3D IC and 2.5D IC packaging beyond AI. As shrinking transistors becomes slower and more expensive, chip designers split large chips into smaller dies and connect them in a single package.

The cause is the rising cost of advanced manufacturing nodes. Large monolithic dies have lower yields and higher costs at leading nodes. Chiplets let companies use the most advanced process only where needed and reuse proven dies for input-output and memory functions. AMD, Intel, and Apple already use chiplet or multi-die designs in processors. Design software from companies such as Siemens, which launched Innovator3D IC in June 2024, and Cadence, which acquired Invecas in January 2024, supports multi-die design. These trends extend packaging demand to servers, PCs, networking, and automotive chips.

Two restraints limit how quickly 3D IC and 2.5D IC packaging capacity can grow.

Thermal and Yield Challenges Limit 3D IC and 2.5D IC Packaging

Thermal management and yield challenges limit how fast 3D IC and 2.5D IC packaging can scale. Stacking dies and placing many chips close together concentrates heat and increases the risk of defects.

The underlying causes are physics and manufacturing complexity. Heat from lower dies in a 3D stack has difficulty escaping, which can reduce performance and reliability. AI packages draw more than 1,000 watts in some cases, requiring advanced cooling such as liquid cooling. Through-silicon vias and fine-pitch bonds must be precisely aligned, and a single defect can ruin an expensive package containing several costly dies. Warpage of large interposers and substrates also causes failures. Testing each die before assembly to confirm it is a known good die adds further cost. These challenges raise production costs and limit yields, especially for the largest AI packages.

High Capital Costs and Supply Concentration Constrain 3D IC and 2.5D IC Packaging

High capital costs and concentrated supply constrain the 3D IC and 2.5D IC packaging market. Building advanced packaging lines requires expensive equipment and cleanrooms, and much of the world’s capacity sits in a few locations.

The specific causes are equipment costs, skilled labor, and geography. Hybrid bonding tools, lithography for interposers, and advanced testing equipment cost millions of dollars each. Capacity for leading 2.5D packaging is heavily concentrated in Taiwan, creating supply risk for chip designers worldwide. Shortages of substrates and interposers have repeatedly delayed product launches. Packaging firms in Taiwan have raised prices; reports in July 2026 indicated ASE increased advanced packaging quotes by more than 20%. Smaller chip designers and start-ups often struggle to secure capacity, which pushes them toward alternative packaging approaches or delays their products.

Onshore Advanced Packaging Opens a New Revenue Pool in North America

Building advanced packaging capacity in North America opens a large new revenue pool for 3D IC and 2.5D IC packaging. Chip designers and governments want to reduce dependence on overseas packaging for AI and defense chips.

Packaging companies and foundries investing in the United States can capture this demand. In March 2025, TSMC announced an additional US$ 100 billion investment in Arizona, including two advanced packaging facilities. In October 2025, Amkor Technology broke ground on a US$ 7 billion packaging and test campus in Peoria, Arizona, with Apple and NVIDIA as customers. In June 2026, TSMC and Amkor signed a 10-year agreement to expand advanced packaging and testing in the United States. Chip designers, hyperscalers, and defense agencies are the main customers for onshore packaging capacity.

Hybrid Bonding and Panel-Level Packaging Create a Next-Generation Revenue Pool

Hybrid bonding and panel-level packaging create a next-generation revenue pool for 3D IC and 2.5D IC packaging. These technologies allow finer connections, larger packages, and lower cost per unit area.

Equipment makers, foundries, and memory makers can capture this opportunity. Hybrid bonding directly joins copper pads without any solder bumps, enabling connection pitches below 10 micrometers. Memory makers are evaluating hybrid bonding for future HBM generations with more stacked dies. Panel-level packaging uses large rectangular panels instead of round wafers, increasing the number of packages per batch and reducing cost for large AI chips. Glass substrates are also being developed for flatter, more dimensionally stable packages. Foundries, memory makers, and equipment suppliers such as Applied Materials, BE Semiconductor Industries, and EV Group are key participants.
