Innovative packaging technology
Innovative manufacturing process is used to realize ultra-thin flexible electronics for applications such as mobile and display. Several techniques have been developed to achieve this goal :

Roll transfer handling system, die flip chip bonded on the flexible substrate, stretchable adhesive film laminated on the SI wafer and flexible interconnection technology.

Flexible ultra thin microelectronics have many applications, including conformal and wearable electronics.
A key to achieving this is the development of techniques to thin Si die to thicknesses less than 50μm.
The techniques have been developed to integrate ultra-thin die onto or into flexible polymeric substrates such as LCP and polyimide.
Roadmap

Flexible package is becoming a trend in semiconductor industry.
HANA Micron are developing a flexible package solution to apply for flexible display, wearable, sensor and memory such as display drive IC, CMOS image sensor and storage product. In the near future, it is expected that HANA Micron will be able to provide a flexible package solution of SIP (System in package) type as well.

Simulation / Reliability and Modeling
It is important to understand and characterize the flexible structure before starting process development. We can simulate and analyze flexible structure to reduce crack of thinned wafer. So we can find out the optimized structure through analytical modeling such as bending and strength characterization.
