摘要:
A method of operating a scanning probe microscope (SPM) includes scanning a sample as a probe of the SPM interacts with a sample, and collecting sample surface data in response to the scanning step. The method identifies a feature of the sample from the sample surface data and automatically performs a zoom-in scan of the feature based on the identifying step. The method operates to quickly identify and confirm the location of features of interest, such as nano-asperities, so as to facilitate performing a directed high resolution image of the feature.

Described are methods and systems for providing improved defect detection and analysis using infrared thermography. Test vectors heat features of a device under test to produce thermal characteristics useful in identifying defects. The test vectors are timed to enhance the thermal contrast between defects and the surrounding features, enabling IR imaging equipment to acquire improved thermographic images. In some embodiments, a combination of AC and DC test vectors maximize power transfer to expedite heating, and therefore testing. Mathematical transformations applied to the improved images further enhance defect detection and analysis. Some defects produce image artifacts, or “defect artifacts,” that obscure the defects, rendering difficult the task of defect location. Some embodiments employ defect-location algorithms that analyze defect artifacts to precisely locate corresponding defects.
摘要:
The present invention generally includes a display device having a plurality of indicia indicative of a vehicle parameter. The display device includes a plurality of dimmable segments. Each dimmable segment has a lower end point associated with a first value of the vehicle parameter and an upper end point associated with a second value of the vehicle parameter. Each of the dimmable segments has an independently adjustable intensity and adapted to illuminate at least a portion of the indicia. A control module is adapted to receive a signal indicative of an actual value of the vehicle parameter. The control module also adjusts the intensity of at least one of the dimmable segments based on the signal. The intensity being at a first intensity when the actual value is about equal to the first value, the intensity being at a second intensity when the actual value is about equal to the second value, and the intensity being at an intensity between the first intensity and the second intensity when the actual value is between the respective first value and the respective second value.
摘要:
An apparatus and method supports thermal processing of a microelectronic device such as a semiconductor chip in a substrate by heating the substrate with secondary radiation from an energy transfer device 40, which has a first set of energy transfer regions comprised of an emissive and thermally conductive material, and a second set of thermally insulating regions comprised of a reduced emissivity and reduced thermal conductivity material or free space. A multi-zone radiant energy source 30 provides radiative energy to energy transfer device 40, with a process controller 36, preferably a multi-zone controller, altering the amount of energy provided by each heat zone associated with each emissive region of energy transfer device 40. Sensors detect the thermal energy level of each energy transfer region to allow controller 36 to adjust the secondary radiation emitted by each region in real time, resulting in a predetermined and controlled distribution of thermal energy on substrate 20. Energy transfer device 40 can have plural emissive and thermally conductive concentric rings separated from each other by reduced emissivity and reduced thermal conductivity regions such as free space gaps 42. Alternatively, a solid plate 54 having an emissive coating or emissive surface 52 can have reduced emissivity and reduced conductivity isolation regions such as trenches 56 for defining the multi-zone high-emissivity and high thermal conductivity energy transfer regions.

Described are autofocusing algorithms and system implementations for machine inspection applications. The disclosed algorithms depend neither on the type of image (visual, infrared, spectrometric, scanning, etc.) nor on the type of image detector. Disclosed image filtering techniques, image focus measure functions and adaptive velocity control methods can be used in computer-based inspection systems for many different types of cameras and detectors as well as for a variety of magnification levels. The proposed autofocusing system can utilize the existing imaging hardware of the inspection system and does not require any additional components.
