• Medical Devices: APT supports the development of advanced medical devices with smaller size, improved functionality, and higher reliability.

Key APT Technologies

Numerous APT technologies have been developed to address the challenges of device packaging, including:

• Fan-Out Wafer-Level Packaging (FOWLP): FOWLP uses a thin die to connect to a fan-out substrate, enabling fine-pitch connections and reduced package size.
• System-in-Package (SiP): SiP integrates multiple components, such as dies, passive devices, and interconnects, into a single package, providing a complete system solution.
• 2.5D/3D Packaging: 2.5D and 3D packaging techniques vertically stack multiple dies or chiplets, creating a multi-layer structure that enhances interconnect density and reduces latency.

Future Trends in APT

APT is continually evolving, with new technologies and advancements emerging:

• Heterogeneous Integration: APT will enable the integration of different types of dies or chiplets, such as CPUs, GPUs, and memory, into a single package.
• Advanced Interconnect Technologies: New interconnect technologies, such as through-silicon vias (TSVs) and nano-interconnects, will provide high-speed and low-power connections within packages.
• Flexible and Stretchable Electronics: APT will support the development of flexible and stretchable devices, enabling applications in wearable electronics and bioelectronics.
