Microfluidic Packaging for Semiconductor Devices

The Challenge

Integrating wet fluidic systems with high-density electronics presents a significant packaging hurdle. There was a need to align and bond complex microfluidic manifolds directly onto semiconductor chips that featured hundreds of tightly spaced input/output points. The primary difficulty was achieving strict enough mechanical tolerances to prevent any fluid leakage or cross-channel contamination—which would instantly short out the electronics—while maintaining a process that was practical for repeatable fabrication.

Our Solution

To solve this, we engineered a specialized, semi-automated alignment tool alongside a new modular cartridge architecture. Rather than relying on error-prone manual placement, the custom tool provided highly repeatable, microscopic alignment between the fluid channels and the chip’s sensor interface. The resulting cartridge design didn’t just physically secure the fluidics; it also incorporated careful impedance matching for the electrical pathways. This dual approach ensured that high-frequency signals remained clean and stable.
