Abstract
A standard cell has gate patterns extending in Y direction and arranged at an equal pitch in X direction. End portions of the gate patterns are located at the same position in Y direction, and have an equal width in X direction. A diode cell is located next to the standard cell in Y direction, and includes a plurality of opposite end portions formed of gate patterns that are opposed to the end portions, in addition to a diffusion layer which functions as a diode.

A semiconductor device, comprising:
- a standard cell having three or more gate patterns extending in a first direction and arranged at an equal pitch along a second direction orthogonal to the first direction;
- and
- a diode cell located next to the standard cell in the first direction, wherein:
- the gate patterns included in the standard cell terminate near a cell boundary between the standard cell and the diode cell, with respective end portions located at a same position in the first direction and having an equal width in the second direction, the diode cell includes:
- a plurality of diffusion region patterns;
- and
- a plurality of opposite end portions formed of a gate pattern, which are located near the cell boundary and opposed to the end portions of the gate patterns included in the standard cell, and
- at least one of the plurality of diffusion region patterns functions as a diode.
