摘要：

Due to the increasing demand for higher performance, greater flexibility, smaller size, and lighter weight in mobile electronic products, there have been growing needs of wearable electronic products in near future.

To realize wearable electronic products, there should be five core electronic hardware technologies - (1) flexible semiconductor, (2)flexible sensors, (3)flexible display, (4) flexible battery and (5) flexible packaging & interconnection technologies. In the flexible semiconductor devices, ICs are thinned down to nanometer thickness, and then transferred to a polymer film. For the flexible sensors, various types of sensors have been introduced using flexible substrates such as FPCs (flexible printed circuits) and conductive fabrics. In contrast, flexible displays are already available by introducing OLED (organic LED) realized on polymer base films. And flexible batteries are also demonstrated by adapting solid electrolytes. However, there has been little development on flexible packaging & interconnection areas.

As one of the promising flexible packaging and interconnection technologies, FPCs and conductive fabric substrates and ACF materials-based packaging and interconnection method will provide the flexible interconnect solution for realizing wearable electronic products.

In the electronic packaging technology for wearable electronics, first, flexible IC packaging structures such as COF(Chip On Flex)/CIF(Chip In Flex) can provide an immediate technical solution for semiconductor IC package flexibility for wearable electronics. Second, FOF(Flex On Flex) and FOF(Flex On Fabric) technologies using FPCs and conductive fabric substrates and ACFs interconnection materials become very important, because ACF interconnection provides excellent electrical flexibility compared with conventional solder- or socket-based interconnection methods which have a limitation of bending and flexing.

In this presentation, it will be presented how the ACFs technology can be successfully used for the COF/CIF chip packaging and FOF interconnection and assembly methods with proven flexibility for wearable electronics applications.
