Abstract: A system includes a container filled with material other than radioactive material. The system also includes a capacitor disposed on the container. The capacitor is disposed over a surface of the container. A power source, e.g., 5 V, is used for powering the capacitor that is connected to the power source through a resistor ranging between 20 and 40 mega ohms.

In one nonlimiting example, the processor is configured to generate a rolling average of the charging/discharging. An output device of the system may be configured to render feedback to the user based on the proximity of the user with respect to the container. In some nonlimiting examples, the output device is configured to render the feedback based on the rolling average.

Abstract: An optical metrology device performs multi-wavelength polarized confocal Raman spectroscopy. The optical metrology device uses a first light source to produce a first light beam with a first wavelength and a second light source to produce a second light beam with a second wavelength. A dichroic beam splitter partially reflects the first light beam and transmits the second light beam to combine the light beams along a same optical axis that is incident on a sample. The dichroic beam splitter directs the Raman response emitted from the sample in response to the first light beam and the second light beam together towards at least one spectrometer and directs the first light beam away from the at least one spectrometer. A chopper may be used to isolate the Raman response to the first and second light beams that is received and spectrally measured by the at least one spectrometer.

Abstract: An alignment or overlay target that has an optically opaque layer disposed between the top and bottom target structure is measured using opto-acoustic metrology. A classifier library is generated for classifying whether an opto-acoustic metrology signal is on or off the bottom structure. A target may be measured by acquiring opto-acoustic measurement data for the bottom structure of the target and determining a location of the bottom structure using opto-acoustic metrology data acquired from the different locations over the bottom structure and the classifier library. Locations for acquisition of the data may be based on classification results of each measurement and a search pattern. The top structure of the target may be optically imaged. The relative position of the top structure with respect to the bottom structure is determined using the opto-acoustically determined location of the bottom structure and the image of the top structure.

Abstract: Disclosed herein are methods for determining the location of a moving target region (e.g., a tumor) based on the location of the center of its range of motion and the location of a target region surrogate, during a radiotherapy treatment session or a quality assurance (QA) session. These methods comprise characterizing the motion range of the target region, calculating the location of the center of the motion range, and determining a correlation between the position of the target region surrogate and the displacement of the target region from the center of the motion range as the target region moves.

Abstract: Vacuum-integrated photoresist-less methods and apparatuses for forming metal hardmasks can provide sub-30 nm patterning resolution. A metal-containing (e.g., metal salt or organometallic compound) film that is sensitive to a patterning agent is deposited on a semiconductor substrate. The metal-containing film is then patterned directly (i.e., without the use of a photoresist) by exposure to the patterning agent in a vacuum ambient to form the metal mask. For example, the metal-containing film is photosensitive and the patterning is conducted using sub-30 nm wavelength optical lithography, such as EUV lithography.
