  • Publication number: 20260198121
    Abstract: A liner for an isolation structure is formed in a device layer of a semiconductor device using one or more high dielectric constant (high-k) dielectric materials. The high-k dielectric material(s) of the liner have a dielectric constant that is greater than the dielectric constant of silicon nitride (SixNy), which enables increased passivation to be achieved for the isolation, and enables reduced current leakage to be achieved for integrated circuit structures in the device layer. The isolation structure and/or the liner may be formed by processes that are compatible with subsequent layers and/or structures that are to be formed in the semiconductor device.

  • Publication number: 20260186295
    Abstract: A method comprises simulating rays deterministically, monitoring the intensity of the rays as they undergo ray splitting, dynamically switching from deterministic simulation to stochastic simulation when the ray intensity declines to a specified threshold, continuing the stochastic simulation to model interference effects up to the specified threshold, and outputting a simulation result that provides an enhanced representation of light propagation within the waveguide that is based on both the deterministic simulation and the stochastic simulation. Systems and methods are disclosed.
