  • Patent number: 9377502
    Abstract: In accordance with an embodiment of the present invention, a method of testing a plurality of semiconductor devices includes applying a stress voltage having a peak voltage on a shield line disposed over a substrate. The substrate has functional circuitry of a semiconductor device. A fixed voltage is applied to a first metal line disposed above the substrate adjacent the shield line. The first metal line is coupled to the functional circuitry and is configured to be coupled to a high voltage node during operation. The peak voltage is greater than a maximum fixed voltage. The shield line separates the first metal line from an adjacent second metal line configured to be coupled to a low voltage node during operation. The method further includes measuring a current through the shield line in response to the stress voltage, determining the current through the shield line of the semiconductor device, and based on the determination, identifying the semiconductor device as passing the test.

  • Patent number: 9348964
    Abstract: A method and apparatus of a novel full chip edge-based mask three-dimensional (3D) model for performing photolithography simulation with consideration for edge coupling effect is described. The method receives a mask design layout in order to perform mask topography effect modeling. The method generates scaling parameters for edge coupling effects. Each scaling parameter has an associated combination of feature width and space. The sum of feature width and space associated with at least one scaling parameter is less than a minimum pitch. The method applies a thick mask model that includes several edge-based kernels to the mask design layout to create a mask 3D residual. To apply the thick mask model to the mask design layout, the method updates the edge-based kernels with the scaling parameters.

  • Patent number: 9335626
    Abstract: A design level compatible with a sidewall image transfer process employs an alternating grid of mandrel-type line tracks and non-mandrel-type line tracks. Target structure design shapes are formed such that all vertices of the target structure design shapes are on the grid. The target structure design shapes are classified as mandrel-type design shapes and non-mandrel-type design shapes depending on the track type of the overlapping line tracks for lengthwise portions. All mandrel-type line tracks and straps of the mandrel-type design shapes less lateral strap regions of the non-mandrel-type design shapes collectively form mandrel design shapes, which can be employed to generate a first lithographic mask. Sidewall design shapes are generated from the mandrel design shapes. Blocking shapes for a second lithographic mask can be generated by selecting all areas that are not included in the target structure design shapes or the sidewall design shapes.

  • Patent number: 9317643
    Abstract: A method for printed circuit board design of temperature sensitive components includes a scrub tool receiving a list of part numbers for electronic components of a printed circuit board assembly (“PCBA”). The scrub tool sends one or more queries for finding temperature and time limits of the electronic components to a database. A mapping tool receives a selection of one or more part numbers responsive to the one or more queries, wherein the selection is responsive to the temperature and time limits. The mapping tool sends a data structure to a physical design tool which is configured with physical design data for generating a graphic representation of the PCBA. The data structure from the mapping tool provides the received selection of one or more part numbers and configures the physical design tool to highlight components having part numbers of the selection on the PCBA graphic representation.

  • Patent number: 9292649
    Abstract: The present disclosure relates to a method of generating a scaled integrated chip design by scaling a FEOL and a BEOL of an original IC design at different scaling ratios, and an associated apparatus. In some embodiments, the method is performed by forming an original integrated chip (IC) design that is a graphical representation of an integrated chip. The original IC design has a front-end-of-the-line (FEOL) section, a back-end-of-the-line (BEOL) section, and a middle-of-the-line (MOL) section that is disposed between the FEOL and BEOL sections. A scaled integrated chip design is formed by scaling (i.e., shrinking) the FEOL section and the BEOL section of the original integrated chip design at different scaling ratios, and by scaling different design layers within the MOL section at different scaling ratios to avoid misalignment errors between the FEOL section and the BEOL section.

  • Patent number: 9280632
    Abstract: In one aspect of an embodiment, a method implemented on a data processing system for circuit design, includes identifying one or more first portions of a design of a circuit, each of the one or more first portions containing a set of elements interconnected via timing nets and generating weights for the timing critical nets, the weights being generated after identifying the one or more first portions and executing a placer algorithm which uses the weights for the timing critical nets to place the set of elements on a representation of the design. In this method, in one embodiment, the weights for the timing critical nets can be generated to have values that differ from weights for non-critical nets. The placer algorithm can be any one of a variety of conventional placer algorithms such as a weighted wire length driven placer algorithm or a force directed timing driven placer algorithm or a min-cut placer algorithm.

  • Patent number: 9223911
    Abstract: Optical simulation can be performed employing a calibrated printing model, in which a unique phase transmission value is assigned to each type of sub-resolution assist features (SRAFs). The printing model can be calibrated employing a mask including multiple test patterns. Each test pattern is defined by a combination of a main feature, at least one SRAF applied to the main feature, and the geometrical relationship between the main feature and the at least one SRAF. Generation of the phase transmission values for each SRAF can be performed by fitting a printing model employing phase shift values and/or transmission values for SRAFs with measured printed feature dimensions as a function of defocus and/or with measured SRAF printing behavior on a printed photoresist layer. A properly calibrated printing model can predict the printed feature dimensions, shift in the best focus, and presence or absence of printed SRAFs.

  • Patent number: 9223916
    Abstract: Various implementations of a method, system, and computer program product for executing timing analysis of an asynchronous clock domain crossing are disclosed. In one embodiment, a signal group and a corresponding timing specification are determined for one or more signals of an electronic design. For each of the signals, a clock associated with the signal is renamed based, at least in part, on the signal group associated with the signal. The asynchronous clock domain between a transmit domain and a receive domain is identified in the electronic design based, at least in part, on identifying a signal path associated with one or more renamed clocks that is asynchronous to a clock associated with the receive domain. For each of the one or more renamed clocks, timing analysis is executed across one or more signals associated with the renamed clock at the asynchronous clock domain crossing.
