  • Patent number: 12381149
    Abstract: Method and structures for shared (dual) sources for a single device in semiconductor devices such as very-large-scale integration (VLSI) devices. The shared-source improves or increases a current that passes through the device (e.g., to a drain region associated with the shared-source), which in turn increases a performance of the device. Example improvements may include a delay improvement of the device and associated logic paths and/or a power improvement for the device. The method includes operations for design improvements during a design process by implementing shared-sources in a semiconductor device design.

  • Publication number: 20250131171
    Abstract: Embodiments herein describe techniques for identifying excess antennas (or antenna diodes) in a IC design using computer software tools. An IC design can be changed for any number of reasons, which can change the number of antennas that are required to sufficiently protect the IC from damage during the fabrication process. Currently, a chip designer would use a ratio to determine whether a portion of the IC (e.g., a macro) has too many or too few antennas. The embodiments herein describe techniques where computer software tools identify excess antennas for the designer. The designer can then decide whether to remove these antennas. In another embodiment, the computer software tools may automatically remove some or all of the identified excess antennas, without input from the chip designer.
