Abstract: A semiconductor structure includes a first backside metal rail that extends across the structure and a second backside metal rail parallel and adjacent to the first backside metal rail. The first and second backside metal rails bound a first circuit row. The structure also includes a backside signal wire that interrupts the second backside metal rail; and a third backside metal rail that extends across the structure parallel and adjacent to the second backside metal rail. The second and third backside metal rails bound a second circuit row. The structure also includes gate metal pitches, which extend across the structure perpendicular to the backside metal rails. The structure also includes a frontside signal wire above the gate metal pitches; and a signal via that penetrates the structure and connects the backside signal wire to the frontside signal wire.

Abstract: A method is provided to increase processor frequency in an integrated circuit (IC). The method includes identifying a gate included in the IC, the gate having a gate threshold voltage and performing a plasma process to form an antenna signal path in signal communication with the gate. The method further comprises adjusting the plasma process or circuit design to increase plasma induced damage (PID) applied to the gate so as to alter the gate threshold voltage.

Abstract: Embodiments for power generation include defining a power tile within a power distribution network having a grid of power rails, the power tile having logic gates, and applying an initial power grid pattern from a plurality of power grid patterns for the power tile such that initial power grid pattern relates to timing characteristics of the logic gates of the power tile. The power grid patterns each have a different number of connectors connecting one power rail to another power rail in the grid of power rails. A subsequent power grid pattern is selected from the power grid patterns for the power tile such that the subsequent power grid pattern meets a threshold condition for the timing characteristics of the logic gates of the power tile. The timing characteristics for the logic gates are determined based on a voltage drop associated with the subsequent power grid pattern.

Abstract: Aspects of the invention include systems and methods configured to provide hierarchical circuit designs that makes use of a color decomposition of library cells having boundary-aware color selection. A non-limiting example computer-implemented method includes placing a plurality of shapes within a hierarchical level of a chip design. The plurality of shapes can include a top boundary shape, a bottom boundary shape, one or more center boundary shapes, and one or more internal shapes. A hierarchical hand-off region is constructed by pinning the top boundary shape to a first mask, pinning the bottom boundary shape to a second mask, and pinning the one or more center boundary shapes to a same mask. The same mask is selected from one of the first mask and the second mask.

Abstract: Methods, systems and computer program products for avoiding Boolean DRC failures during cell placement are provided. Aspects include generating a semiconductor layout by filling a plurality of rows within a macro block with cells including functional cells and fill cells. Aspects also include modifying the semiconductor layout by removing one or more fill cells from the macro block to create a gap. Aspects also include examining a set of cells that border edges of the gap to identify one or more predicted rule violations. Based on the identified one or more predicted rule violations, aspects also include modifying the semiconductor layout to change a shape of the gap to avoid the one or more predicted rule violations.
