Abstract
A solid-state imaging device is provided that includes a first substrate including at least a first electrode, a first modification layer, a first low-permittivity layer formed on the first modification layer, and a first joint surface where the first electrode and the first modification layer are exposed; and a second substrate including at least a second electrode, a second modification layer, a second low-permittivity layer formed on the second modification layer, and a second joint surface where the second electrode and the second modification layer are exposed. The first modification layer has higher hydrophilicity than the first low-permittivity layer. The second modification layer has higher hydrophilicity than the second low-permittivity layer. The first substrate and the second substrate form a laminate structure and are electrically connected by bonding the first joint surface and the second joint surface.
