摘要： An optical emission microscopy system with a macro optic system having a high numerical aperture for obtaining global views of an integrated circuit Device Under Test (DUT). The DUT is subjected to illumination and stimulation conditions, and images are obtained to form a "global difference" image in which defects, wherever located in the chip, can be discerned by the system operator. The operator can select apparent "defect bright spots" to be further inspected, and zoom in with the higher magnification micro optics system to repeat the image formation steps. "Difference images" are processed to further eliminate noise spots using an improved two-stage filtering operation. The system may be operated under manual or automatic control, and may be interfaced to various data input, storage, and output devices as desired.

摘要： A method and apparatus for improved defocus detection on wafers. The use of hyperspectral imaging provides increased sensitivity for local defocus defects, and the use of Fourier Space analysis provides increased sensitivity for extended defocus defects. A combination of the two provides improved overall sensitivity to local and extended defocus defects.

摘要： An inspection system for detecting anomalies on a substrate. The inspection system has a sensor array for generating image data. A first high speed network is coupled to the sensor array and receives and communicates the image data. An array of process nodes is coupled to the first high speed network, and receives and processes the image data to produce anomaly reports. Each process node has an interface card coupled to the first high speed network, that receives the image data from the first high speed network and formats the image data according to a high speed interface bus protocol. The interface card sets a register indicating whether a predetermined amount of image data has been stored in a memory, and the process node reads the register to determine whether the predetermined amount of image data has been stored in the memory, and initiates image processing when the register indicates that the predetermined amount of image data has been stored in the memory.

摘要： Systems and methods for inspection of a specimen are provided. One system includes an illumination subsystem configured to illuminate the specimen by scanning a spot across the specimen. The system also includes a non-imaging detection subsystem configured to generate output signals responsive to light specularly reflected from the spot scanned across the specimen. In addition, the system includes a processor configured to generate images of the specimen using the output signals and to detect defects on the specimen using the images. In one embodiment, the non-imaging detection subsystem includes an objective and a detector. An NA of the objective does not match a pixel size of the detector. In another embodiment, the non-imaging detection subsystem includes an objective having an NA of greater than about 0.05. The system may be configured for multi-spot illumination and multi-channel detection. Alternatively, the system may be configured for single spot illumination and multi-channel detection.

摘要： Wafer inspection systems and methods are provided. One inspection system includes a module measurement cell coupled to a host inspection system by a wafer handler. The module measurement cell is configured to inspect a wafer using one or more modes prior to inspection of the wafer by the host inspection system. The one or more modes include backside inspection, edge inspection, frontside macro defect inspection, or a combination thereof. Another inspection system includes two or more low resolution electronic sensors arranged at multiple viewing angles. The sensors are configured to detect light returned from a wafer substantially simultaneously. A method for analyzing inspection data includes selecting a template corresponding to a support device that contacts a backside of a wafer prior to inspection of the backside of the wafer. The method also includes subtracting data representing the template from inspection data generated by inspection of the backside of the wafer.
