A method of hybridizing an FPA having an IR component and a ROIC component and interconnects between the two components, includes the steps of: providing an IR detector array and a Si ROIC; depositing a dielectric layer on both the IR detector array and on the Si ROIC; patterning the dielectric on both components to create openings to expose contact areas on each of the IR detector array and the Si ROIC; depositing indium to fill the openings on both the IR detector array and the Si ROIC to create indium bumps, the indium bumps electrically connected to the contact areas of the IR detector array and the Si ROIC respectively, exposed on a top surface of the IR detector array and the Si ROIC; activating exposed dielectric layers on the IR detector array and the Si ROIC in a plasma; and closely contacting the indium bumps of the IR detector array and the Si ROIC by bonding together the exposed dielectric surfaces of the IR detector array and the Si ROIC. Another exemplary method provides a pillar support of the indium bumps on the IR detector array rather than a full dielectric layer support. Another exemplary method includes a surrounding dielectric edge support between the IR detector array and the Si ROIC with the pillar supports.

Embodiments of a thermal compression bonding (TCB) process cooling manifold, a TCB process system, and a method for TCB using the cooling manifold are disclosed. In some embodiments, the cooling manifold comprises a pre-mixing chamber that is separated from a mixing chamber by a baffle. The baffle may comprise at least one concentric pattern formed through the baffle such that the primary cooling fluid in the pre-mixing chamber is substantially evenly distributed to the mixing chamber. The pre-mixing chamber may be coupled to a source of primary cooling fluid. The mixing chamber may have an input configured to accept the primary cooling fluid and an output to output the primary cooling fluid.

In a plasma processing step that is used in the method of manufacturing the element chip for manufacturing a plurality of element chips by dividing a substrate which has a plurality of element regions and of which an element surface is covered by insulating film, the substrate is divided into element chips by exposing the substrate to a first plasma, element chips having first surface, second surface, and side surface are held spaced from each other on carrier, insulating film is in a state of being exposed, recessed portions are formed by retreating insulating film by exposing element chips to second plasma for ashing, and then recessed portions are covered by protection films by third plasma for formation of the protection film, thereby suppressing creep-up of the conductive material to side surface in the mounting step.
