Abstract:
1. A semiconductor device comprising: a circuit cell including a plurality of elements aligned in a first direction; and a basic end cell arranged adjacent to the circuit cell in the first direction and having a compensation capacitor capable of being connected to a supply voltage of the circuit cell, wherein a diffusion layer forming the compensation capacitor extends along the first direction in a predetermined region of the circuit cell, and wherein the compensation capacitor has a transistor structure in which a gate line is arranged over the diffusion layer, and the gate line extends along the first direction in the predetermined region in parallel to the diffusion layer, wherein a first basic end cell arranged at one end in the first direction of the circuit cell is provided as the basic end cell, and a second basic end cell arranged at the other end in the first direction of the circuit cell is provided as the basic end cell, wherein the diffusion layer forming the compensation capacitor and the gate line thereabove are shared by the first and second basic end cells.
