  • Patent number: 11354476
    Abstract: There is a significant precaution when performing random dopant fluctuation by using the drift-diffusion model that is the basis of the conventional device simulation. Because the continuation by a long wavelength approximation was done to derive said drift-diffusion model. That is how to recover the location dependence of discrete impurity ions in the long wavelength approximation. For example, in the case that there is an impurity ion near to the interface to an insulating film, the charge density of an impurity ion, which was made continuous in the conventional method, is unable to catch the charge density change due to polarization at the interface. Because this polarization is dependent of the location of a discrete impurity ion near to the interface.

  • Patent number: 11341289
    Abstract: A method for modeling a refurbishing geometry of a component comprises removing a portion to be refurbished from the component, thereby obtaining a truncated component, with a cut surface and a boundary line of the cut surface. Image data of the truncated component are obtained and a representation of the image data is imported into a CAD system. A CAD model of the component, for instance in an unused and nominal new condition, is provided and aligning with the imported representation of the truncated component. Points are defined on the surface of the CAD model and arranged on rows. For each row, a point on the representation of the boundary line of the cut surface closest to the row is determined, and the points in each row are displaced in a translational displacement until the row intersects the representation of the boundary line, thereby obtaining a morphed CAD model representative of the refurbishing geometry of the component.

  • Patent number: 11334690
    Abstract: A method of determining a modified shape of a computer-aided design model of an object or a partition thereof is described. With the method, at least two reference landmarks are placed at a reference position with respect to the shape of the object or to the partition. An adjustment landmark is placed at the reference position of the corresponding reference landmark. The adjustment landmarks are displaced from the reference position to a modified position, and a displacement between the modified position and the reference position is obtained. The modified shape of the object or the partition is generated by modifying the shape of the object or the partition by applying a homogeneous function of the displacement to the computer-aided design model of the shape of the object or the partition.

  • Patent number: 11301596
    Abstract: An engineering design tool and methods for using the same are disclosed. A method may include receiving at least one parent design and generating a plurality of first-generation design copies that each include a characteristic that has mutated from the parent design. New generations of design copies are successively produced from the additional design copies based on fitness testing the new generations of design copies. Characteristics from intergenerational design copies that are not within the same generation are utilized to perform intergenerational crossover, and a likelihood of a mutation of a design copy is increased in response to a threshold number of generations without an improvement in a fitness score of a design copy. New generations continue to be successively produced until a likelihood that any design copy with a higher fitness score will be produced is below a statistical threshold.
