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

Claim 9:
10. A semiconductor device, comprising:
a substrate;
a first stack structure, a second stack structure, a third stack structure, a fourth stack structure, a fifth stack structure, and a sixth stack structure formed over the substrate, wherein the first through sixth stack structures all extend along a first lateral direction, wherein the second stack structure is separated from each of the first and third stack structures with a first distance along a second lateral direction perpendicular to the first lateral direction, the fifth stack structure is separated from each of the fourth and sixth stack structures with the first distance along the second lateral direction, and the third stack structure is separated from the fourth stack structure with a second distance along the second lateral direction, and wherein the second distance is greater than the first distance;
first source/drain structures coupled to respective ends of an upper portion of the first stack structure;
second source/drain structures coupled to respective ends of an upper portion of the second stack structure;
first dielectric trenches coupled to respective ends of an upper portion of the third stack structure;
second dielectric trenches coupled to respective ends of an upper portion of the fourth stack structure;
third source/drain structures coupled to respective ends of an upper portion of the fifth stack structure; and
fourth source/drain structures coupled to respective ends of an upper portion of the sixth stack structure.
