Integrated circuit having hybrid sheet structure

An integrated circuit (IC) structure comprising:

• first through fourth nano-sheet structures extending in a first direction, the second and third nano-sheet structures being between the first and fourth nano-sheet structures;
• first through fourth via structures electrically connected to corresponding ones of the first through fourth nano-sheet structures;
• first through fourth metal-like defined (MD) segments extending in a second direction and overlapping corresponding ones of the first through fourth via structures, the first through fourth MD segments being included in S/D structures of one or more transistors;
• and
• a back-side power distribution structure disposed such that the first through fourth nano-sheet structures are between the back-side power distribution structure and the MD segments, wherein:
• the second and third via structures electrically connect the second and third nano-sheet structures to a first portion of the back-side power distribution structure that is configured to carry one of a power supply voltage or a reference voltage, and
• the first and fourth via structures electrically connect the first and fourth nano-sheet structures to a second portion of the back-side power distribution structure that is configured to carry the other of the power supply voltage or the reference voltage.
