Flip chip die-to-wafer bonding faces challenges for industry adoption due to a variety of technical gaps or process integration factors that are not fully developed to high volume manufacturing(HVM)maturity.In this paper,flip-chip and wire bonding are compared,then flip-chip bonding techniques are compared to examine advantages for scaling and speed.Specific recent 3-year trends in flip-chip die-to-wafer bonding are reviewed to address the key gaps and challenges to HVM adoption.Finally,some thoughts on the care needed by the packaging technology for successful HVM introduction are reviewed.
