Advanced Packaging

An umbrella term for high-tech semiconductor packaging methods that bundle multiple chips into a single high-performance system.

Advanced packaging refers to a suite of state-of-the-art techniques used to aggregate, connect, and protect multiple semiconductor chips (or chiplets) within a single, highly integrated system. Unlike traditional packaging, which simply houses a single silicon die and connects it to a circuit board, advanced packaging uses 2.5D, 3D, hybrid bonding, and high-density substrates. This allows different components to communicate as if they were on a single piece of silicon, enabling faster processing speeds, lower power consumption, and smaller physical footprints. For investors, advanced packaging is a critical secular growth theme in the technology and hardware sectors. As physical limitations make it harder and more expensive to shrink individual transistors (the traditional path of Moore's Law), chipmakers are increasingly relying on advanced packaging to achieve performance gains. This shift drives massive capital expenditure toward specialized equipment suppliers, inspection platforms, and materials providers. When evaluating companies in this space, investors look at their exposure to leading-edge packaging architectures (such as Chip-on-Wafer-on-Substrate, or CoWoS) and monitor metrics like packaging-related revenue growth, market share gains against legacy packaging methods, and customer adoption rates among major foundries and outsourced semiconductor assembly and test (OSAT) providers.

A semiconductor equipment manufacturer sells advanced packaging inspection systems. If the company sells 20 systems at $5,000,000 each, its advanced packaging segment revenue is 20 $5,000,000 = $100,000,000, which investors compare to legacy segment revenues to measure the adoption rate of high-end packaging technology.
