Abstract: A semiconductor device includes one or more active semiconductor components, wherein a front side is defined over the semiconductor substrate and a back side is defined beneath the semiconductor substrate. A front side power rail is formed at the front side of the semiconductor device and is configured to receive a first reference power voltage. First and second back side power rails are formed on the back side of the semiconductor substrate and are configured to receive corresponding second and third reference power voltages. The first, second and third reference power voltages are different from each other.

Abstract: A semiconductor device includes a first gate structure extending along a first lateral direction. The semiconductor device includes a first interconnect structure, disposed above the first gate structure, that extends along a second lateral direction perpendicular to the first lateral direction. The first interconnect structure includes a first portion and a second portion electrically isolated from each other by a first dielectric structure. The semiconductor device includes a second interconnect structure, disposed between the first gate structure and the first interconnect structure, that electrically couples the first gate structure to the first portion of the first interconnect structure. The second interconnect structure includes a recessed portion that is substantially aligned with the first gate structure and the dielectric structure along a vertical direction.

Abstract: A display panel is provided, which includes a first substrate having a first surface, a second substrate having a second surface facing the first surface and having at least an opening portion extending downward from the second surface, wherein the opening portion occupies an area no greater than that occupied by a portion of the second surface other than the opening portion, a liquid crystal layer sandwiched between the first substrate and the second substrate, at least a first spacer disposed between the first substrate and the second substrate, and at least a second spacer disposed between the first substrate and the second substrate, wherein an end of the second spacer is within the opening portion.
