    摘要: A method for separately calibrating an optical model and a resist model of lithography process using information derived from in-situ aerial image measurements to improve the calibration of both the optical model and the resist model components of the lithography simulation model. Aerial images produced by an exposure tool are measured using an image sensor array loaded into the exposure tool. Multiple embodiments of measuring aerial image information and using the measured aerial image information to calibrate the optical model and the resist model are disclosed. The method of the invention creates more accurate and separable optical and resist models, leading to better predictability of the pattern transfer process from mask to wafer, more accurate verification of circuit patterns and how they will actually print in production, and more accurate model-based process control in the wafer fabrication facility.

    摘要: Methods are disclosed to create efficient model-based Sub-Resolution Assist Features (MB-SRAF). An SRAF guidance map is created, where each design target edge location votes for a given field point on whether a single-pixel SRAF placed on this field point would improve or degrade the aerial image over the process window. In one embodiment, the SRAF guidance map is used to determine SRAF placement rules and/or to fine tune already-placed SRAFs. In another embodiment the SRAF guidance map is used directly to place SRAFs in a mask layout.

    摘要: A Video and Audio Front End Assembly and Method. The device and method of this invention takes advantage of the hardware improvements available in personal computing machines that enable higher speed bus communications and much greater computational capacity. The system converts many of the processes needed to convert analog video and audio inputs so that they are displayable by a personal computer from a hardware integrated circuit to a set of software routines. The system combines a simplified hardware front-end interface between the computer and the analog input signals and a very flexible set of software applications running on the host computer. The hardware front end employs an integrated circuit device that is much lower in complexity and cost than the conventional audio/video decoder integrated circuit. The software back end provides performance that is equal to the prior hardware-based systems, while also having the substantial benefit of being upgradable at virtually no cost to respond to changing user requirements and technological evolutions in the decoding arena.
