    摘要: One embodiment of a method for detecting, sampling, analyzing, and correcting hot spots in an integrated circuit design allows the identification of the weakest patterns within each design layer, the accurate determination of the impact of process drifts upon the patterning performance of the real mask in a real scanner, and the optimum process correction, process monitoring, and RET improvements to optimize integrated circuit device performance and yield. The combination of high speed simulation coupled with massive data collection capability on actual aerial images and/or resist images at the specific patterns of interest provides a complete methodology for optimum RET implementation and process monitoring.

    摘要: A method of using an in-situ aerial image sensor array is disclosed to separate and remove the focal plane variations caused by the image sensor array non-flatness and/or by the exposure tool by collecting sensor image data at various nominal focal planes and by determining best focus at each sampling location by analysis of the through-focus data. In various embodiments, the method provides accurate image data at best focus anywhere in the exposure field, image data covering an exposure-dose based process window area, and a map of effective focal plane distortions. The focus map can be separated into contributions from the exposure tool and contributions due to topography of the image sensor array by suitable calibration or self-calibration procedures. The basic method enables a wide range of applications, including for example qualification testing, process monitoring, and process control by deriving optimum process corrections from analysis of the image sensor data.

    摘要: There are many inventions described and illustrated herein. In one aspect, the present invention is directed to a technique of, and system for autonomously monitoring fabrication equipment, for example, integrated circuit fabrication equipment. In one embodiment of this aspect of the invention, the present invention is an autonomous monitoring device including one or more event sensors (for example, acceleration, motion, velocity and/or inertial sensing device(s)) to detect a predetermined event of or by the fabrication equipment (for example, an event that is indicative of the onset, commencement, initiation and/or launch of fabrication process or sub-processes of or by the fabrication equipment). In response thereto, one or more process parameter sensors sample, sense, detect, characterize, analyze and/or inspect one or more parameters of the process in real time (i.e., during the fabrication process).
