Patent ID: 11894299
Assignee: TAIWAN SEMICONDUCTOR CO., LTD.
Field: Semiconductors (Electrical engineering)
Classification: CPC H | IPC H

Claim 7:
8. A method for forming a semiconductor device comprising:
forming a first insulating layer over a substrate, the substrate having a conductive feature;
exposing a first portion and a second portion of the first insulating layer;
exposing a third portion and a fourth portion of the first insulating layer, wherein the fourth portion overlaps the first portion;
removing the first portion, the second portion, the third portion, and the fourth portion to form a first recess, a second recess, a third recess, and a fourth recess, respectively, wherein the fourth recess exposes the conductive feature, wherein the first recess, the second recess, and the third recess extends only partially through the first insulating layer;
forming a conductive material in the first recess, the second recess, the third recess, and fourth recess to form a first conductive line in the first recess, a second conductive line in the second recess, a third conductive line in the third recess, and a conductive via in the fourth recess; and
depositing a second insulating layer over the first insulating layer.
