Integrated circuit devices

A circuit device comprising:

• a substrate that includes diffusion break patterns;
• a first cell that includes a first cell structure on an upper surface of the substrate;
• a second cell that includes a second cell structure on the upper surface of the substrate;
• signal tracks on the upper surface of the substrate, wherein the signal tracks are electrically connected to the first cell structure and/or the second cell structure;
• a first power delivery track on a lower surface of the substrate, wherein the lower surface of the substrate is opposite to the upper surface of the substrate in a first direction;
• and
• a power delivery region that is bounded by the first cell at a first boundary and is bounded by the second cell at a second boundary, wherein the second boundary is opposite to the first boundary with respect to the power delivery region in a second direction that intersects the first direction,
• wherein the power delivery region includes a first power delivery contact and at least one active pattern,
• wherein the first power delivery track is electrically connected to the first cell structure and the second cell structure through the first power delivery contact, and
• wherein the power delivery region is free of the diffusion break patterns.

A circuit device comprising:

• a substrate that includes diffusion break patterns;
• a first cell that includes a first cell structure on an upper surface of the substrate;
• a second cell that includes a second cell structure on the upper surface of the substrate, wherein the second cell structure is spaced apart from the first cell structure in a first direction;
• signal tracks on the upper surface of the substrate, wherein the signal tracks are electrically connected to the first cell structure and/or the second cell structure;
• a power delivery track on a lower surface of the substrate, wherein the lower surface of the substrate is opposite to the upper surface of the substrate in a second direction that intersects the first direction;
