iNEMI Packaging Tech Topic Series: Damage-Free Rapid Electron Beam Testing for Advanced Packaging

Estimated reading time: 1 minute

Testing issues are limiting chip makers’ ability to create larger SOCs (system-on-chip). The scan field dimensions of EUV (extreme ultraviolet light) and NA (numerical aperture) EUV, which are typically used for testing, are too small. To enable larger chips, manufacturers are migrating to system-on-a-package (SOP). This transition requires segmenting the final chip into many chiplets/tiles and reassembling the components using a combination of interposers, base tiles, EMIBs and substrates. 

The active chiplets/tiles, such as CPU cores, GPUs, memory and I/Os, are tested the same as SOCs, with advanced logic testers and BIST (built-in self-test).  BIST is made possible by the active silicon within the chiplets/tiles. The interposers, base tiles, EMIBs and substrates, which are the building blocks of SOPs, lack the active silicon to make traditional testing possible. To test these foundational building blocks of SOP, massive electrical contacting arrays of probes have been used. This method is slow, expensive, inflexible, and worst of all, can damage the device under test.

Applied Materials’ Yield Technology Group (YTG) has developed a non-contacting electron beam tester to enable testing of SOP building blocks. This presentation will introduce the Applied Materials damage-free electron beam testing method that can ensure high yield of SOP building blocks.
