  • Patent number: 8759415
    Abstract: A molding composition and a method of forming a pattern. The method includes forming on a substrate a molding layer of a molding composition of aromatic divinyl ethers; pressing the template into the molding layer, the template having a relief pattern, the molding layer filling voids in the relief pattern, the template not contacting the substrate; exposing the molding layer to actinic radiation, the actinic radiation converting the molding layer to a cured molding layer having thick and thin regions corresponding to the relief pattern; removing the template; filling the thin regions of the relief pattern with a backfill material; removing regions of the molding layer not protected by the backfill material to expose regions of the substrate; forming trenches in the exposed regions of the substrate; and removing any remaining molding layer and backfill material. A transfer layer may be used between the molding layer and the substrate.

  • Patent number: 7179571
    Abstract: An optical apparatus used for the efficient characterization of photoresist material includes at least one grating interferometer having at least two gratings that together define an optical recombination plane. An optical stop blocks any zeroth order beam from propagating through the apparatus. A reticle positioned at the recombination plane has at least one fiducial marking therein. A lithographic imaging optical tool is positioned so that its input optical plane is substantially coincident with the optical recombination plane and its output imaging plane is substantially coincident with photoresist on a wafer. The apparatus writes in the photoresist latent, sinusoidal grating patterns, preferably of different spatial frequencies, as well as at least one fiducial mark whose pattern is determined by the marking in the reticle. After the photoresist is developed, its intrinsic spatial resolution may be determined by automated means.

  • Patent number: 5826065
    Abstract: A stochastic simulation method and system are provided. The invention eliminates the need for the use of subroutine calls in a user-written simulation program, and of option flags to direct execution via decision trees, by allowing the user to configure the simulator through choices of options at run-time. The options are presented via a user interface as radio buttons or checkboxes which the user activates. The simulator sets itself up to incorporate only those options. The programmer (that is, the author of software according to the invention) only makes the objects available and ensures that they work together. It is the user who actually configures the simulator. The invention provides a highly extendable structure. By use of inheritance and dynamic allocation of memory, and by design of self-contained objects to represent various components of the simulation system, a simulation program according to the invention incorporates new features and options with a minimum of new code.

  • Patent number: 5745385
    Abstract: A system and method for simulating a mechanistic kinetic process, such as a chemical process including one or more chemical reactions, over a predetermined time period, subject to a programmed temperature variation, is provided. The simulation proceeds stochastically, by taking discrete time steps through the time period. The time steps vary in size, based on instantaneous reaction rate values for the reactions taking place. Reaction rates can vary by many orders of magnitude, and sometimes a stochastically calcualated time step will be so great that it might skip over a later increase in chemical activity. To avoid loss of accuracy and control of the simulation due to such excessively large time steps, when the stochastically determined time step exceeds a threshold, one or more smaller, deterministic time steps are made. The deterministic time steps "inch" forward in time, until an increase in chemical activity is detected. Then, stochastic time steps are resumed.
