en.Wedoany.com Reported - TSMC, a wafer foundry company in Taiwan, China, plans to integrate one trillion transistors in a single package by 2030. The technological path will no longer rely solely on single-process scaling but will combine multiple capabilities such as advanced logic processes, CoWoS advanced packaging, SoIC system-level stacking, and co-packaged optics, providing higher-density system integration solutions for future AI and high-performance computing chips. This goal signifies that semiconductor competition is shifting from "transistor count per chip" to "transistor scale at the package level."

TSMC's roadmap, presented at the 2026 European Technology Symposium, shows that future AI applications require larger-scale computing units, higher-bandwidth memory, shorter interconnect paths, and lower-power data transmission. Continuing to increase the area and transistor count of a single chip faces limitations in manufacturing yield, mask size, power density, and cost. Integrating logic chips, HBM high-bandwidth memory, interconnect structures, optoelectronic conversion modules, and other functional units into the same package through multi-chip integration and advanced packaging has become a key approach to further improving system performance.

CoWoS is one of the core technologies in TSMC's AI chip packaging roadmap. This technology combines GPUs, AI accelerators, HBM memory, and other chips into the same package through interposers and high-density interconnects. As demand for large model training and inference increases, AI chip performance is no longer solely determined by the performance of a single computing chip but also by data throughput between chips and memory, package area, heat dissipation capability, and system-level bandwidth. TSMC plans to continuously expand the size of CoWoS packages, advancing to a 14x reticle size version by 2028 and a larger-scale solution by 2029, enabling more computing and storage units to be accommodated within a single package.

SoIC plays a key role in the direction of 3D stacking. Unlike traditional side-by-side packaging, SoIC can shorten the connection distance between chips through vertical stacking, improving signal transmission efficiency and providing more space for heterogeneous integration. The future trillion-transistor single package does not mean manufacturing a single monolithic trillion-transistor chip but rather combining multiple chiplets with different functions and processes into a system-level device through Chiplet and 3D heterogeneous integration. This approach is more suitable for AI computing, as AI chips need to simultaneously handle logic computation, memory access, network interconnection, and power control.

Co-packaged optics is also an important direction in TSMC's roadmap. As AI cluster scales expand, the cost of moving data between chips, packages, servers, and data center networks increases, and electrical interconnects face limitations in distance, bandwidth, and power consumption. Co-packaged optics brings optical engines closer to computing and switching chips, reducing electrical signal transmission bottlenecks and providing high-speed interconnect capabilities for larger-scale AI systems. TSMC's proposal to support future packaging platforms with technologies like COUPE indicates that advanced packaging is evolving from "chip assembly" to an integrated platform for computing, storage, and communication.

This plan also aligns with TSMC's outlook on the global semiconductor market. TSMC expects the global semiconductor market to exceed $1.5 trillion by 2030, with AI and high-performance computing accounting for a major share. The increasing demand from AI accelerators for wafer manufacturing, advanced packaging, HBM integration, and system interconnects is driving wafer foundries to extend their capacity building from front-end processes to back-end packaging and system integration. For TSMC, the trillion-transistor single-package goal is both a technological roadmap and a demonstration of long-term supply capabilities for AI customers.

From an industry impact perspective, TSMC's plan will strengthen the role of advanced packaging in semiconductor competition. In the past, process nodes were the main indicator of foundry technology capability; now, customers are more focused on obtaining greater system computing power within controllable power consumption and manufacturing costs. NVIDIA, AMD, Broadcom, cloud service providers' self-developed chips, and AI server platforms all require coordination between front-end processes, packaging capacity, HBM supply, and high-speed interconnects. Whoever can provide more comprehensive system-level manufacturing capabilities is more likely to occupy a key position in the AI chip supply chain.

However, the trillion-transistor single package by 2030 remains a roadmap target and does not mean mass production has been achieved. Whether this goal can be realized depends on advanced packaging yield, HBM supply, thermal materials, packaging substrates, optical interconnect maturity, design tool chains, and customer product cycles. In particular, issues such as warpage, thermal stress, interconnect reliability, and testing costs associated with ultra-large package sizes will affect the speed of commercialization. TSMC needs continuous coordination between processes, packaging, materials, and system design to transform the roadmap into mass-producible AI computing platforms.

TSMC's plan to achieve a trillion-transistor single package by 2030 indicates that semiconductor technology evolution is entering a new phase driven by "system integration." Advanced processes remain important, but transistor scaling alone can no longer meet the growing demand for AI computing power. In the coming years, CoWoS, SoIC, co-packaged optics, and Chiplet design will collectively determine the performance ceiling of AI chips and reshape the division of labor in the wafer foundry, packaging and testing, memory, optical communication, and server industry chains.
