Abstract:
1. A method, comprising: forming a first passivating layer on conductive interconnecting structures of a first substrate, using a process chosen from a group consisting of an atomic layer deposition process and a Langmuir-Blodgett technique; forming a second passivating layer on conductive interconnecting structures of a second substrate, using a process chosen from a group consisting of an atomic layer deposition process and a Langmuir-Blodgett technique; aligning the first substrate to the second substrate so that the conductive interconnecting structures of the first and second substrates are in physical contact but are separated by the first and second passivating layers; and thermo compression bonding the first substrate to the second substrate, thereby causing the conductive interconnecting structures of the first and second substrates to make electrical contact through the passivating layers.
