Advances and Challenges in Flip-Chip Packaging

The role of semiconductor packaging has evolved from space transformation and environmental protection, to becoming an important enabler for silicon and system performance. This paper will examine some of the advances in flip-chip packaging as an enabler of power delivery and power removal using a microprocessor as an example. In addition, the role of the package as an enabler of system I/O performance and silicon back-end reliability will be examined.
