Assignee: TAIWAN SEMICONDUCTOR MANUFACTURING COMPANY LTD.
Field: Semiconductors (Electrical engineering)
Classification: CPC H | IPC H

Claim 15:
16. A method comprising:
providing a first dielectric layer that includes a first conductive feature, a second conductive feature, a first polymeric feature disposed on the first conductive feature and a second polymeric feature disposed on the second conductive feature;
forming a second dielectric layer on the first dielectric layer, the second dielectric layer being formed of a different material than the first dielectric layer;
forming a first hole through the second dielectric layer to expose the second polymeric feature;
removing at least a portion of the exposed second polymeric feature to form a second hole that is in communication with and offset from the first hole; and
forming a third conductive feature within the first and second holes.
