Title: Indium Surface Preparation for Improved Flip-Chip Hybridization
Agency: DOD
Contract: W909MY-11-C-0067
Award Amount: $727,272.00


The purpose of this SBIR research is to develop an Indium Oxide (InOx) inhibitor coating for applications to high performing Large Format and High Definition FPAs with a fast hybridization cycle time and high yield. The primary constraint for this method of hybridization is an Indium Oxide layer present on the surface of the Indium bumps at elevated temperatures. The Indium Oxide layer, at the scales and form factors of future FPA products, effectively packages the pure Indium and prevents free form reflow of the Indium bump. This restricts the effectiveness and capability of the FPA and ROIC bond process. The technology being developed in this SBIR will solve this fundamental material limitation. A solution to this fundamental material property is required to advance state of the art FPA technology.
