  • System and method for dynamic ESD Protection
    Patent number: 6898061
    Abstract: A system and method for dynamically protecting a vulnerable device from an ESD event includes an ESD event sensor and a breakdown voltage adjustment circuit. The ESD event sensor detects an ESD event and provides a signal to the breakdown voltage adjustment circuit indicating that an ESD event has occurred. The breakdown voltage adjustment circuit receives the signal from the ESD event sensor and adjusts the breakdown voltage of the vulnerable device during the ESD event.

  • System and method for defining a semiconductor device layout
    Patent number: 6804809
    Abstract: A method to create a layout of a semiconductor device for the purpose of fabricating the semiconductor device involves first providing a plurality of partial-area layout cells and then generating the layout of the semiconductor device by placing the plurality of the partial-area layout cells together. The layout can be conveniently expanded to a desirable size by replicating or repeating certain repeatable cells.
