Patent ID: 11935893
Assignee: TAIWAN SEMICONDUCTOR MANUFACTURING COMPANY LTD.
Field: Semiconductors (Electrical engineering)
Classification: CPC H | IPC H

Claim 16:
17. A semiconductor device including a plurality of standard cells, wherein:
the plurality of standard cells include a first group of standard cells arranged in a first row extending in a row direction, a second group of standard cells arranged in a second row extending in the row direction, and a third group of standard cells arranged in a third row extending in the row direction,
the first group of standard cells, the second group of standard cells and the third group of standard cells are arranged in a column direction,
at least two of a first cell height of the first group of standard cells in the column direction, a second cell height of the second group of standard cells in the column direction and a third cell height of the third group of standard cells in the column direction are different from each other, and
the first cell height of the first group of standard cells, the second cell height of the second group of standard cells and the third cell height of the third group of standard cells are determined based on a number of metal wirings arranged along the column direction within each of plurality of standard cells, the metal wirings being located at a level closer to a substrate than a level at which the first and second power supply wirings are located.
