Abstract
A method for forming an interconnection structure for a semiconductor device and an interconnection structure is disclosed. The method includes forming a conductive layer on an insulating layer and etching the conductive layer to form a first conductive line. Thereafter, a spacer is formed on a side wall of a first end portion of the first conductive line. The method further includes forming a second conductive line, parallel to the first conductive line, having a second end portion, wherein a side wall of the second end portion is arranged to abut the spacer such that the first and the second metal line are extending along the same line and separated by the spacer. A recess is formed in the second metal line, extending along a portion of the second metal line, and a second mask layer is arranged in the recess.
