摘要： A wafer having improved inspection sensitivity to foreign matter on a top-most surface of the wafer, as detected with a surface scanning optical inspection system that uses an inspection wavelength. The wafer includes a substantially homogenous first layer at the top-most surface of the wafer, the first layer having a first thickness. The first layer is at least partially transparent to the inspection wavelength. A substantially homogenous second layer immediately underlies the first layer, the second layer having a second thickness. The second layer is at least partially transparent to the inspection wavelength. A substrate immediately underlies the second layer. The first thickness and the second thickness are set in a combination that produces a local minimum of an electric field at the top-most surface and a local maximum of an electric field within one hundred nanometers above the top-most surface.

摘要： Various methods and systems for detection of selected defects particularly in relatively noisy inspection data are provided. One method includes applying a spatial filter algorithm to raw inspection data acquired across an area on a substrate to determine a first portion of the raw inspection data that has a higher probability of being a selected type of defect than a second portion of the raw inspection data. The selected type of defect includes a non-point defect. The method also includes generating a raw two-dimensional map illustrating the first portion of the raw inspection data. In addition, the method includes searching the raw two-dimensional map for an event that has spatial characteristics that approximately match spatial characteristics of the selected type of defect. The method further includes determining if the event corresponds to a defect having the selected type.

摘要： A scanning force microscope having a sensor head and a base wherein a moveable sample holder is housed in the base and is positioned relative to a probe housed in the sensor head, such sample being monitored by an optical deflection detection system. The detection system is configured to provide direct visual observation of the probe with respect to the sample. The mirror of the detection system is mounted in a cut away portion of a sphere and defines the axis of rotation of a kinematic mount, such providing ease of fine adjustment of the detection system. The sensor head is in communication with the base by a stage kinematic mount, such providing ease of position adjustment of the sensor head with respect to the base.

摘要： A scanning probe microscope having numerous advantages is disclosed. Respective scanning force and scanning tunneling probes are removably mounted in the head using kinematic mounting techniques so that they may be substituted for one another without the need to adjust the cantilever deflection sensor. A linear position-sensitive photodetector in the deflection sensor eliminates further the need for adjustments. A motorized, non-stacked x,y coarse movement stage is kinematically positioned with respect to the base and features a minimized mechanical loop to reduce thermal and vibrational effects on the position of the sample. A z coarse movement stage positions the head kinematically with respect to the base and includes a motorized drive means which allows the height, tilt and pitch of the probe to be adjusted. The scanner includes x,y and z sample position detectors which provide an accurate measurement of the position of the sample with respect to the probe. The z position detector provides an output which is exclusive of sample tilt and which may be used as an output of the scanning probe microscope. The outputs of the x,y and z position detectors may also be connected in feedback loops with the controller to improve the performance of the scanning probe microscope.

摘要： A single-axis active vibration reducing system for reducing vibrations in an object in a single axis. The vibration isolation system enables the sensing of motion of the center of mass of an object along a single axis and, with the proper positioning of a single sensor-actuator pair with feedback operation, the dampening of vibrations of the object along that axis. Due to the positioning and alignment of the actuator, the vibration isolation system of the present invention does not introduce appreciable off-axis vibration. The vibration reducing system includes an actuator positioned on the object to impart an actuation force along an actuator axis to reduce vibrations of the object in the vibrational axis without imparting substantial motion to the object other than in the vibrational axis.
