Abstract:
A method for fabricating semiconductor device includes the steps of first forming a first dielectric layer on a substrate, in which a first conductor is embedded within the first dielectric layer. Next, a second dielectric layer is formed on the first dielectric layer, part of the second dielectric layer is removed to form a contact hole, and a lateral etching process is conducted to expand the contact hole to form a funnel-shaped opening. Next, a metal layer is formed in the funnel-shaped opening, and the metal layer is planarized to form a second conductor.

Claim (Index 1):
A method for fabricating semiconductor device, comprising:\n providing a substrate; forming a first dielectric layer on the substrate; forming a via hole in the first dielectric layer; and performing a lateral etching process to expand the via hole for forming a funnel-shaped opening.
