  • Patent number: 7398486
    Abstract: The present invention provides a new approach and algorithm to optimize various design parameters in global routing. According to an exemplary aspect of the present invention, marked trees are first preprocessed. For every vertex incident to leaves, one may go through the list of its leaves, and if two leaves have the same mark one may leave only one of them. After that whether homeomorphism exists may be determined. The reason behind selecting such homeomorphic pairs is as follows: adding or removing a vertex of degree 2 as well as adding or removing a new leaf (variable) does not significantly modify routing (in this case all routing transformations are in essence splitting and merging routing trees). After the selection of applicable transformations, one may apply them to optimize design parameters.

  • Patent number: 7396760
    Abstract: The present invention is directed to a method and system of intelligent dummy filling placement to reduce inter-layer capacitance caused by overlaps of dummy filling area on successive layers. The method and system treats each consecutive pair of layers together so as to minimize dummy filling overlaps between each layer. In particular, dummy fill features on each layer may be placed in a checkerboard pattern to avoid overlaps. As such, the present invention may eliminate large overlap area of the dummy patterns on consecutive layers by utilizing intelligent dummy filling placement.

  • Patent number: 7397105
    Abstract: A deep n-well is formed beneath the area of a capacitor structure. The use of a deep n-well lessens the parasitic capacitance by placing a diode in series with the interlayer dielectric cap. The deep n-well also reduces substrate noise. Once the n-well is implanted and annealed, a cross hatch of shallow trench isolation is patterned over the n-well. The shallow trench isolation reduces and confines the inductively and/or capacitively coupled surface currents to small areas that are then isolated from the rest of the chip.

  • Publication number: 20080163145
    Abstract: A method of determining whether voltage from an aggressor net exceeds a voltage threshold on a victim net design in an integrated circuit design. Probabilistic noise from the aggressor net on the victim net is calculated. The probabilistic noise is checked against the voltage threshold, and the victim net design is passed when the probabilistic noise does not exceed the voltage threshold. When the probabilistic noise does exceed the threshold, then an effective noise at a desired mean time to failure is computed, and the effective noise is checked against the voltage threshold. The victim net design is passed when the effective noise does not exceed the voltage threshold, and failed when the effective noise does exceed the threshold.

  • Patent number: 7394703
    Abstract: The invention proposes am improved twin MONOS memory device and its fabrication. The ONO layer is self-aligned to the control gate horizontally. The vertical insulator between the control gate and the word gate does not include a nitride layer. This prevents the problem of electron trapping. The device can be fabricated to pull the electrons out through either the top or the bottom oxide layer of the ONO insulator. The device also incorporates a raised memory bit diffusion between the control gates to reduce bit resistance. The twin MONOS memory array can be embedded into a standard CMOS circuit by the process of the present invention.

  • Patent number: 7395522
    Abstract: A graphical profile map for integrated circuits on a substrate. The graphical profile map includes a depiction of die placement boundaries and shot placement boundaries for the integrated circuits on the substrate. Also included are integrated circuit property information contours, where the contours are not limited to either of the die placement boundaries or the shot placement boundaries. In this manner, three key pieces of information for the integrated circuits are presented, including integrated circuit property information, die placement, and shot placement. Because these three pieces of information are presented in a graphical form, it is much easier to interpret the information. For example, it is much easier to determine which shot and die placements have properties that are at risk, and which shot and die placements have adequate property profiles.

  • Patent number: 7395478
    Abstract: A methodology for generating scan based transition patterns (i.e., ATPG pattern generation for transition delay faults (“TDF”)) wherein when either a slow-to-rise (STR) or a slow-to-fall (STF) transition fault is detected, that specific fault is removed from a fault universe as well as its companion TDF, wherein the companion fault is a fault on the same node as the detected fault but has the opposite transition. In other words, if a slow-to-rise (STR) transition fault is detected, the slow-to-rise (STR) transition fault is removed from the fault universe as well as its corresponding slow-to-fall (STF) transition fault (and vise versa). By removing companion faults as well as those which are specifically detected, pattern generation run time is reduced as well as the total pattern count for the final delay test pattern.
