摘要:
An exclusive-or circuit includes a pass gate controlled by a second input node. The pass gate is connected to pass through a version of a logic state present at a first input node to an output node when so controlled. A transmission gate is controlled by the first input node. The transmission gate is connected to pass through a version of the logic state present at the second input node to the output node when so controlled. Pullup logic is controlled by both the first and second input nodes. The pullup logic is connected to drive the output node low when both the first and second input nodes are high. An exclusive-nor circuit is defined similar to the exclusive-or circuit, except that the pullup logic is replaced by pulldown logic which is connected to drive the output node high when both the first and second input nodes are high.
摘要:
A semiconductor device includes a substrate and a number of diffusion regions defined within the substrate. The diffusion regions are separated from each other by a non-active region of the substrate. The semiconductor device includes a number of linear gate electrode tracks defined to extend over the substrate in a single common direction. Each linear gate electrode track is defined by one or more linear gate electrode segments. Each linear gate electrode track that extends over both a diffusion region and a non-active region of the substrate is defined to minimize a separation distance between ends of adjacent linear gate electrode segments within the linear gate electrode track, while ensuring adequate electrical isolation between the adjacent linear gate electrode segments.
摘要:
Methods, structures and designs for self-aligned local interconnects are provided. The method includes designing diffusion regions to be in a substrate. Some of a plurality of gates are designed to be active gates and some of the plurality of gates are designed to be formed over isolation regions. The method includes designing the plurality of gates in a regular and repeating alignment along a same direction, and each of the plurality of gates are designed to have dielectric spacers. The method also includes designing a local interconnect layer between or adjacent to the plurality of gates. The local interconnect layer is conductive and disposed over the substrate to allow electrical contact and interconnection with or to some of the diffusion regions of the active gates. The local interconnect layer is self-aligned by the dielectric spacers of the plurality of gates.
