    摘要: Problematic open areas are identified in a semiconductor wafer layout. The problematic open areas have a size variation relative to one or more neighboring open areas of the layout sufficient to cause adverse microloading variation. In one embodiment, the adverse microloading variation is controlled by shifting a number of layout features to interdict the problematic open areas. In another embodiment, the adverse microloading variation is controlled by defining and placing a number of dummy layout features to shield actual layout features that neighbor the problematic open areas. In another embodiment, the adverse microloading variation is controlled by utilizing sacrificial layout features which are actually fabricated on the wafer temporarily to eliminate microloading variation, and which are subsequently removed from the wafer to leave behind the desired permanent structures.

    摘要: An invention is provided for a feed forward circuit that reduces delay through an inverting circuit. The feed forward circuit includes an inverter having an input and an output, and an inverting circuit having an input and an output. The input of the inverting circuit is coupled to the output of the inverter. A feed forward transistor having a gate coupled to the input of the inverter and a terminal coupled to the output of the inverting circuit also is included. In operation the feed forward transistor decreases the amount of time required for the output of the inverting circuit to change state. In sum, the invention reduces the delay when the inverting circuit transitions to a high state, without affecting the timing of the transition to a low state.

    摘要: Regular layout shapes are placed in accordance with a virtual grate. A determination is made as to whether an unoccupied layout space adjacent to a regular layout shape to be reinforced, and extending in a direction perpendicular to the regular layout shape, is large enough to support placement of a sub-resolution shape. Upon determining that the unoccupied layout space is large enough to support placement of the sub-resolution shape, the sub-resolution shape is placed so as to be substantially centered upon a virtual line of the virtual grate within the unoccupied layout space. Also, one or more sub-resolution shapes are placed between and parallel with neighboring regular layout shapes when windows of lithographic reinforcement associated with each of the neighboring regular layout shapes permit. The sub-resolution shapes may be placed according to a virtual grate, or may be placed based on proximity to edges of the neighboring regular layout shapes.
