Assignee: UNISANTIS ELECTRONICS SINGAPORE PTE. LTD.
Field: Semiconductors (Electrical engineering)
Classification: CPC H  B | IPC H

Claim 10:
11. The method for manufacturing the three-dimensional semiconductor device according to claim 1, the method comprising steps of:
in parallel with a step of forming the second band-like material layer having the first band-like layer on its top, forming a thirteenth band-like material layer having a twelfth band-like material layer of a same planar shape on its top, extended in the first direction, on the first material layer;
in parallel with a step of forming the fourth band-like material layer having the third band-like layer on its top, forming a fifteenth band-like material layer having a fourteenth material layer of a same planar shape on its top, extended in the first direction, on the first material layer;
forming a sixteenth band-like material layer between the opposing fourth band-like material layer and the fifteenth band-like material layer, in contact with each side surface of them, and having a shape the same as the sixth band-like material layer; and
removing the third band-like material layer, the fourth band-like material layer, the fourteenth band-like material layer, and the fifteenth band-like material layer.
