Abstract:
A method of fabricating a semiconductor device includes providing a first substrate comprising a first conductive element exposed at a surface of the first substrate; forming a patterned photoresist layer atop the first conductive element, whereby the patterned photoresist layer provides openings exposing the first conductive element; forming a first metal layer in the openings and directly atop the first conductive element; forming a first insulator layer over the first metal layer and the first substrate; and polishing the first metal layer and the first insulator layer, resulting in a first interface surface over the first substrate wherein the first interface surface includes part of the first metal layer and the first insulator layer.

Claim (Index 16):
A method of fabricating a semiconductor device, the method comprising:\n providing a first substrate having a first conductive element; forming a first metal feature over the first conductive element, wherein the first metal feature and the first conductive element are substantially aligned; forming a first oxide layer over the first metal feature; polishing the first oxide layer and the first metal feature; providing a second substrate having a second conductive element; forming a second metal feature over the second conductive element, wherein the second metal feature and the second conductive element are substantially aligned; forming a second oxide layer over the second metal feature; polishing the second oxide layer and the second metal feature; and bonding the first and the second substrates such that the first and the second metal features are substantially aligned and in contact, and the first and the second insulator layers are in contact.
