Technology Summary

How to increase the packaging density of electronic product with integral substrate and advanced interconnect are prime issues needed to be addressed first in electronic packaging in order to meet consumers demand for light-weight, compact, reliable and multifunctional electronic or communication devices. In the aspect of high-density interconnection, nanoscale surface activated interconnect, nanowire/carbon-tube bump, etc. may dramatically increase the density of interconnection. In the aspect of integral substrate, built-in passive components with nanomaterials, such as resistors, capacitors, inductors and filters can remarkably increase the density of integral substrate. Therefore, nanomaterials applied for electronic packaging could be the solution to satisfy the needs for innovation and integration in information, communication and consumer electronics industries by enabling manufacturers to develop lighter, more compact, more integrated, and more competitive products.
