  • 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.

  • Publication number: 20230205075
    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.

  • 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.

  • Patent number: 10825735
    Abstract: A semiconductor structure and a method for fabricating the semiconductor structure are provided. The method includes providing a substrate. The substrate includes an active region and a blank region disposed adjacent to the active region. The method also includes forming a fin material layer on the substrate. Further, the method includes forming a plurality of fins on the active region, and a plurality of dummy fins on the blank region by etching the fin material layer. A spacing between a fin and an adjacent dummy fin is greater than a spacing between adjacent fins.

  • Patent number: 10586859
    Abstract: A semiconductor structure and a method for fabricating the semiconductor structure are provided. The method includes providing a semiconductor substrate including a dense region and a sparse region. The method also includes forming initial fins equally spaced apart from one another on the semiconductor substrate, the initial fins including a plurality of intrinsic fins and dummy fins. The intrinsic fins on the dense region has a spatial density greater than the intrinsic fins on the sparse region. In addition, the method includes forming a first isolation layer on the semiconductor substrate. The first isolation layer covers a portion of sidewalls of the dummy fins and a portion of sidewalls of the intrinsic fins. Further, the method includes forming first trenches in the first isolation layer by removing the dummy fins, and forming a second isolation layer in the first trenches.
