Abstract
A semiconductor device includes a plurality of standard cells. The plurality of standard cells include a first group of standard cells arranged in a first row extending in a row direction and a second group of standard cells arranged in a second row extending in the row direction. The first group of standard cells and the second group of standard cells are arranged in a column direction. A cell height of the first group of standard cells in the column direction is different from a cell height of the second group of standard cells in the column direction.
Claims20
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 and a second group of standard cells arranged in a second row extending in the row direction,
- the first group of standard cells and the second group of standard cells are arranged in a column direction, and
- a cell height of the first group of standard cells in the column direction is different from a cell height of the second group of standard cells in the column direction,
- each of the plurality of standard cells includes a first power supply wiring for supplying a first potential and a second power supply wiring for supplying a second potential different from the first potential, and
- a cell height of each of the plurality of standard cells is a distance in the column direction between a center line, extending in the row direction, of the first power supply wiring and a center line, extending in the row direction, of the second power supply wiring.
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 and a second group of standard cells arranged in a second row extending in the row direction,
- the first group of standard cells and the second group of standard cells are arranged in a column direction,
- a cell height of the first group of standard cells in the column direction is different from a cell height of the second group of standard cells, and
- the cell height of the first group of standard cells and the cell height of the second group of standard cells are determined based on a number of fin structures arranged along the column direction within each of plurality of standard cells.
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 and a second group of standard cells arranged in a second row extending in the row direction,
- the first group of standard cells and the second group of standard cells are arranged in a column direction,
- each of the plurality of standard cells includes a first power supply wiring for supplying a first potential and a second power supply wiring for supplying a second potential different from the first potential,
- a cell height of the first group of standard cells in the column direction is different from a cell height of the second group of standard cells in the column direction, and
- the cell height of the first group of standard cells and the cell height of the second 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.
