Latest Patents

One of Parker's latest patents is titled "Current-aligned auto-generated non-equiaxial hole shape for wiring." This invention presents a method, system, and program product for replacing isotropic hole shapes in a wiring layout with non-equiaxial hole shapes. These shapes are arranged in the direction of current flow, which increases current flow along the wire's longitudinal axis while decreasing it along the transverse axis. The invention also accommodates the limitations of copper CMP within an automated tool without sacrificing the efficiency of a hand-tuned layout. Additionally, it includes a semiconductor device featuring at least one non-equiaxial hole shape.

Another significant patent is "Structure and method for sub-resolution dummy clear shapes for improved gate dimensional control." This invention involves a mask system used by lithographic systems to project an image of a circuit design. The design includes at least one large feature and at least one nearby small feature. The mask comprises shapes to project an image of the small feature and an opaque shape to project the large feature. The opaque shape includes at least one dummy clear shape that is insufficient to be resolved, allowing for improved gate dimensional control.
