Article: Flip-Chip Integrated Circuits.(Technology Information)

Enabling low-cost commercial millimeterwave systems

Part one of this article (Nov. 2000) described the evolution of FCIC technology. It presented the core elements of FCICs-flip-chip die attach and coplanar transmission lines-and compared FCICs to the traditional chip-and-wire technology. The fundamental advantage of the FCIC approach is that expensive gallium arsenide (GaAs) and indium phosphide (InP) chip area is not used for passive components, resulting in significantly lowered system manufacturing costs.

This second part of the article presents the many other advantages of using FCICs. It also describes the challenges faced by designers using this ...
