Abstract
The invention provides a semiconductor structure. The semiconductor structure includes a substrate, a first inter metal dielectric (IMD) layer, a second inter metal dielectric layer and a third inter metal dielectric layer sequentially arranged on the substrate. The first inter metal dielectric layer includes at least one first wire, the second inter metal dielectric layer includes at least one mask layer, and the third inter metal dielectric layer includes at least one third wire and a super via. The super via penetrates through the second inter metal dielectric layer, and electrically connect to the first wire and the third wire, and part of the super via directly contacts the mask layer in the second inter metal dielectric layer.
