摘要:
A conductive via of a semiconductor device includes a relatively small diameter portion extending into an active surface of a fabrication substrate and a corresponding, relatively large diameter portion that extends into a back side of the fabrication substrate. This type of conductive via may be fabricated by forming the relatively small diameter portion before or during BEOL processing, while the large diameter portion of each conductive via may be fabricated after BEOL processing is complete. Electronic devices that include one or more semiconductor devices with such conductive vias are also disclosed.
