Application Note: Developing Miniature Power Blocks Attached to Wafer-Scaled IC

Prepared by Oussama Berriah, MSc Candidate (UQTR) Under Supervision of Ahmed Lakhssassi (UQO) and the DreamWafer® Research Team, in co-operation with CMC Microsystems.

This application note captures the design experience of the DreamWafer Team on the development of miniature power blocks. the power blocks are used to supply power to a wafer-scale IC while allowing adequate heat conduction from the wafer-scale IC through the power blocks to the attached heat sinks and providing structural support to the fragile silicon wafer. Thermal, mechanical, and electrical issues are explored in this application note.
