Inter-substrate coupling and alignment using liquid droplets can include electrical and plasmon modalities. For example, a set of droplets can be placed on a bottom substrate. A top substrate can be placed upon the droplets, which uses the droplets to align the substrates. Using the droplets in a capacitive or plasmon coupling modality, information or power can be transferred between the substrates using the droplets.

A substrate bonding method is able to reliably bond substrates while avoiding a reduction in yield made worse by finer pitches. The substrate bonding method can include: forming an adhesive resin layer on a surface of a first substrate on which a pad has been formed; forming an opening on the adhesive resin layer above the pad; filling the opening with molten solder to form a pillar-shaped solder bump; and applying heat and pressure to the first substrate and a second substrate while a terminal formed on the second substrate is aligned with the solder bump.
