Wafer packaging deal for solid state battery

Iten in France is working with the A*STAR Institute of Microelectronics (A*STAR IME) to integrate solid state battery technology into 3D packaging at the wafer level.
This will enable system-in-package(SiP) designs to combine the solid state battery with microcontrollers. The wafer-level integration in a single package not only reduces assembly complexity but also improves interconnect reliability. With fewer solder joints and connectors, the potential points of failure decline, which can lead to higher reliability.

This also reduces power losses, resulting in improved overall performance while reducing the device footprint for next-generation portable and wearable devices. The two organizations are actively exploring future applications in consumer electronics, medical devices, and the Internet of Things (IoT) where compactness and energy efficiency are critical.
A*STAR IME’s research is based on three architecture families: high density fan-out wafer-level packaging (HD FOWLP); 2.5D interposer; and 3D interposers. This has led to eight platforms where the solid state batteries can be integrated.
It also works on mold-first FOWLP, redistribution layer (RDL)-first FOWLP, passive interposer, active interposer, photonic interposer, wafer-to-wafer (W2W) hybrid bond, chip-to-wafer (C2W) hybrid bond, and C2W micro-bump.
ITEN’s solid state batteries are free from hazardous materials, providing a safer, eco-friendly alternative. By enabling longer device life and reducing the need for external power components, this innovation contributes to minimizing electronic waste.
“We are pleased to collaborate with ITEN to develop breakthrough advanced packaging technologies that meet the needs of the growing microelectronics market. Such efforts will enable new applications of SiP, creating new market opportunities,” said Terence Gan, Executive Director of A*STAR IME.
Vincent Cobee, CEO of ITEN, added, “A*STAR IME’s strong knowledge and expertise in advanced packaging technologies support us in accelerating the development of new micro batteries optimized for integration into SiP. This is a major step forward in addressing the challenges of energy efficiency across a wide spectrum of applications.”
