Interposer and fan-out wafer-level packaging represent advanced semiconductor packaging technologies aimed at enhancing the performance of electronic devices. An interposer serves as a bridge between the silicon die and the package substrate, facilitating high-density interconnections and efficient signal routing. Meanwhile, fan-out wafer-level packaging redistributes the chip's I/O pads across a larger area, thereby increasing I/O density and enabling thinner package designs. Both technologies, Interposer and Fan-Out Wafer Level Packaging (FOWLP), contribute significantly to improving electronic device performance and integration density.

Within the interposer and fan-out wafer-level packaging market, the primary packaging types include 2.5 dimensional (2.5D) and 3 dimensional (3D) configurations. 2.5D packaging involves stacking multiple dies on an interposer or substrate, which enhances performance and density compared to conventional packaging methods while also reducing the overall form factor. These packaging technologies encompass various approaches such as through-silicon vias, interposers, and fan-out wafer-level packaging. They find applications across diverse sectors including micro-electro-mechanical systems (MEMs), sensors, imaging and optoelectronics, memory, logic integrated circuits (ICs), light-emitting diodes (LEDs), and others. End-users benefiting from these technologies span consumer electronics, telecommunications, industrial sectors, automotive industries, military and aerospace, smart technologies, and medical devices.North America was the largest region in the interposer and fan-out wafer level packaging market in 2025.
