Overlay is one of the most critical process control steps of semiconductor manufacturing technology. A typical advanced scheme includes an overlay feedback loop based on after litho optical imaging ...
The importance of traditionally acceptable sources of variation has started to become more critical as semiconductor technologies continue to push into smaller technology nodes. New metrology ...
New EVG ® 40 D2W overlay metrology system provides 100 percent overlay measurement on every die at up to 15X higher throughput versus industry benchmark ST. FLORIAN, Austria, Sept. 8, 2025 /PRNewswire ...
Imec has developed a Cu-to-Cu and SiCN-to-SiCN die-to-wafer bonding process resulting in a Cu bond pad pitch of only 2µm at <350nm die-to-wafer overlay error, achieving good electrical yield. Such ...
Imec and EVG have demonstrated 1.8µm pitch overlay accuracy for wafer-to-wafer bonding. Wafer-to-wafer bonding is a promising technique for enabling high-density integration of future ICs through 3D ...
(MENAFN- PR Newswire) The EVG40 D2W can be used for any D2W bonding application, including chiplet integration, high-bandwidth memory (HBM) stacks, and 3D system on chip (SoC) integration processes, ...
