Semiconductor integrated circuit, standard cell, standard cell library, semiconductor integrated circuit designing method, and semiconductor integrated circuit designing equipment

A semiconductor integrated circuit, comprising:

• a first transistor including a first gate extending in a first direction and a first diffusion region and which is configured to be active;
• a second transistor including a second gate extending in the first direction and a second diffusion region and which is arranged adjacent to the first transistor in a second direction intersected at a right angle with the first direction;
• and
• a third transistor including a third gate extending in the first direction and the first diffusion region and which is arranged adjacent in the second direction to the first transistor on an opposite side to the second transistor,
• wherein a space between the first gate and the second gate is larger than a space between the first gate and the third gate, and
• the first gate, the second gate and the third gate are included in at least one of a plurality of standard cells.
