Semiconductor device, fabrication method for a semiconductor device and electronic apparatus
First Claim
1. A semiconductor device, comprising:
- a first substrate having a bonding face to which a first electrode and a first insulating film are exposed;
an insulating thin film configured to cover the bonding face of said first substrate; and
a second substrate having a bonding face to which a second electrode and a second insulating film are exposed and bonded to said first substrate in a state in which said insulating thin film is sandwiched between the bonding face of said second substrate and the bonding face of said first substrate and said insulating thin film is sandwiched between the first electrode and the second electrode, wherein said first electrode and said second electrode are electrically connected to each other through said insulating thin film.
