Enabling Indium Interconnects for Emerging Technologies Indium has long been used in infrared imaging and detector applications, but growing investment in quantum computing, cryogenic electronics, advanced sensors, and space systems is driving renewed interest in indium-based interconnect technologies. Unlike conventional solder materials, indium offers exceptional compliance, low-temperature bonding, and superconducting behavior at cryogenic temperatures, making it uniquely suited for applications where reliability and performance must be maintained under extreme operating conditions. Electroplated indium bumping provides a scalable approach for manufacturing the fine-pitch interconnects required by these next-generation devices. Key Process Requirements - Fine-pitch bump formation - Uniform bump height - Tight thickness control - High process repeatability - Production-ready throughput Successfully meeting these requirements depends on both plating chemistry and reactor design.
