But this shift demands a fundamental rethinking of how chips are made.

Traditional semiconductor manufacturing, focused on shrinking transistors on a 2D plane, is hitting physical limits. For on-device AI, the challenge isn’t just raw processing power, but delivering that power with minimal latency, in a tiny form factor, and without draining battery life or overheating the device. Imagine a smartphone performing complex image rendering or running a large language model in real-time, all while remaining cool to the touch and lasting a full day. This seemingly impossible feat relies on an unsung hero: advanced semiconductor packaging. As The Verge reported recently, the next generation of iPhones is likely to come with a higher price tag, a clear indicator that soaring memory and packaging costs, driven by AI demands, are becoming unavoidable.

Advanced packaging transcends the conventional “chip-in-a-box” approach. Instead, it involves stacking multiple chips vertically, integrating different functionalities – like logic, memory, and specialized AI accelerators – into a single, compact unit. This not only reduces the physical space required but dramatically shortens the distances data must travel, slashing latency and energy consumption. It’s the difference between a sprawling suburban network and a dense, efficient metropolis. This shift is quietly reshaping the economics and engineering of every mobile device. The question then becomes, who is building the intricate machinery that makes this possible?

Q2. Korea’s Quiet Supremacy: How Advanced Packaging Equipment Powers the AI Device Boom?

While global tech giants showcase the dazzling AI capabilities of their latest devices, the true enablers are hidden deep within the supply chain. Here in Korea, companies like Hanmi Semiconductor are not just participants; they are critical architects of this invisible revolution. Established in 1980 by Kwak Noh-kwon, an engineer with a background at Motorola, Hanmi has grown into one of the world’s leading suppliers of semiconductor packaging equipment, specializing in systems for die cutting, cleaning, testing, grinding, and, crucially, thermocompression bonding (TCB).

TCB is a precision technique used to bond stacked chips together with extreme accuracy and minimal thermal stress. It’s the backbone of High-Bandwidth Memory (HBM) and other 3D stacking technologies, which are indispensable for AI accelerators. Without TCB, achieving the hundreds of thousands of microscopic connections needed between vertically integrated memory layers and a logic die, all within fractions of a millimeter, would be impossible. This is why Hanmi Semiconductor’s technology is central to the supply chains of memory powerhouses like SK hynix and Samsung Foundry, who produce the HBM chips powering everything from data centers to now, increasingly, on-device AI.

[Original Analysis] What’s often overlooked is the specific challenge Hanmi’s technology solves for *on-device* AI versus data center AI. Data centers can manage heat with massive cooling systems and aren’t constrained by battery life. Mobile devices, however, demand extreme thermal efficiency and ultra-low power consumption. Hanmi’s advanced chip bonding ensures not just speed and density, but also the structural integrity and thermal dissipation critical for these miniaturized, power-sensitive applications. This nuanced capability is a key reason why Korean innovation in AI chip packaging is so important. With Hanmi Semiconductor currently trading around ₩225,750 and boasting a market cap of approximately $21.4 billion, its valuation reflects the critical, if often unseen, role it plays in this global tech shift.

The continued evolution of on-device AI will depend entirely on how effectively these packaging innovations can scale.
