1/26/2006 - Chipworks, the industry leader in reverse engineering and analysis of semiconductor chips and systems, was the first inside Intel's 65nm Presler and Yonah processors. Chipworks announced that through detailed analysis of the technology inside these devices they have uncovered the first widespread adoption in microprocessors of Copper Pillar Bumping (CPB) technology used to connect the die to the printed wiring board.

"The silicon process technology and strained silicon science being manufactured at 65nm is nothing short of amazing," says Gary Tomkins, manager of Technical Intelligence at Chipworks. "Intel has also taken an additional significant development leap with this new advanced packaging technology."
"Previous Intel processor generations such as the 'Prescott' used conventional flip-chip technology with lead-tin (Pb-Sn) solder balls," adds Dick James, senior technology advisor at Chipworks. "For the Yonah and Presler, Intel has switched to a process that uses plated copper pillars to form the interconnection between die and board. This reduces the lead content over traditional flip-chip packaging even in the latest "Pb-free" devices This is the first processor seen by Chipworks to use this advanced flip-chip technique."
Copper Pillar Bumping in flip-chip assembly offers higher connection density, better electrical and heat-dissipating performance, greater mechanical strength and potentially increased reliability.
"Our customers continue to rely on Chipworks' high levels of detailed and timely technical information to improve their processes and maintain their competitive position," says Dick James, "Information such as the first widespread use of CPB technology revealed in our Presler and Yonah analysis can make a significant difference in the developments that our customers have underway today."
