Issues In Ramping Advanced Packaging


Multi-die assemblies require significantly more test data than a monolithic chip. Thermal mismatch between different layers can cause warping, which puts stress on the bonds that connect those layers, resulting in failures during testing. The big problem is that traditional daisy-chained test approaches cannot pinpoint where problems are occurring. Instead, they provide a go/no-go for the entir... » read more
