  • Patent number: 12596300
    Abstract: Systems and methods for performing local Critical Dimension Uniformity (CDU) modeling in a virtual fabrication environment are discussed. More particularly, local CD variance is replicated in the virtual fabrication environment in order to produce a CDU mask that can be used during a virtual fabrication sequence to produce more accurate results reflecting the CD variance of features that occurs in a pattern for a semiconductor device being physically fabricated.
    Type: Grant

  • Publication number: 20250164965
    Abstract: Systems and methods for performing 3D photoresist profile generation for a semiconductor device fabrication environment are discussed. The methods comprise receiving in a virtual fabrication environment a top contour mask and a bottom contour mask, creating a loading map using a subset of density information extracted from the top contour mask and the bottom contour mask, performing an etch operation using the loading map to generate the 3D photoresist profile, and outputting a result of the etch operation.

  • Publication number: 20230335405
    Abstract: A system, method, and/or non-transitory computer readable medium may implement or be configured to implement the following computational operations associated with electrochemical or vapor phase deposition: (a) defining an interface of a substrate where deposition of a deposited material is to occur or is occurring; (b) using a computational model of the deposition to determine a local deposition rate of the deposited material at multiple locations on the interface, where the computational model of the deposition computes the local deposition rate as a function of one or more geometric parameters of the one or more recessed or protruding features; and (c) computationally adjusting the location of the interface to produce an adjusted interface.

  • Patent number: 11620431
    Abstract: Systems and methods for performing depth-dependent oxidation modeling and depth-dependent etch modeling in a virtual fabrication environment are discussed. More particularly, a virtual fabrication environment models, as part of a process sequence, oxidant dispersion in a depth-dependent manner and simulates the subsequent oxidation reaction based on the determined oxidant thickness along an air/silicon interface. Further the virtual fabrication environment performs depth-dependent etch modeling as part of a process sequence to determine etchant concentration and simulate the etching of material along an air/material interface.

  • Publication number: 20220382953
    Abstract: Systems and methods for performing reflow modeling in a virtual fabrication environment are discussed. More particularly, the virtual fabrication environment may determine metal or material “reflow” or movement during fabrication of a semiconductor device structure. A reflow modeling step with user-specified parameters may be inserted into a process sequence used during fabrication of the semiconductor device structure.
