Here, Vidya Vijay, Director of Business Development at Nordson Test and Inspection, examines how intelligent in-situ sensing is helping manufacturers to achieve these objectives while supporting the ...
Asymmetries in wafer map defects are usually treated as random production hardware defects. For example, asymmetric wafer defects can be caused by particles inadvertently deposited on a wafer during ...
Unpatterned wafer inspection, which has flown well under the radar for most of the semiconductor industry, is becoming more critical amid the need to find defects earlier in the manufacturing process ...
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 ...
Ring-oscillator process monitors give production test teams a fast on-die frequency measurement for identifying CMOS process variation and sorting dies at wafer level. A process monitor is a dedicated ...
The elimination of sawing kerf loss combined with its ability to make thinner wafers of high quality make the implant-cleave wafering approach technically and economically attractive. For example, ...
