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

Claim 11:
12. A method of forming an integrated circuit (IC) structure, the method comprising:
forming a conductive line structure in the IC, the forming the conductive line structure including:
forming line segments resulting in the following:
the line segments being non-overlapping of each other;
the line segments having long axes that extend in a first direction; and
the line segments being offset in a second direction relative to each other, the second direction being orthogonal to the first direction;

forming long pillars organized into sets resulting in the following:
the long pillars having long axes that extend in the second direction;
member long pillars of each set being separated from each other relative to the first direction;
the long pillars being offset in the first direction relative to each other;
the long pillars being overlapping of corresponding ones of the line segments;
the long pillars being organized further into groups;
the groups being offset from each other relative to each of the first direction and the second direction;
each of the groups having a same quantity of the long pillars;
for each of the groups, the member long pillars thereof being offset relative to the first direction;
for each of the groups, member long pillars thereof being non-overlapping of each other relative to the first direction;
for each of the groups, the member long pillars thereof having corresponding first ends which are aligned relative the second direction; and

forming vias which electrically connect the long pillars with corresponding ones of the line segments.
