Optics is the branch of physics that studies the behaviour and properties of light, including its interactions with matter and the construction of instruments that use or detect it. Optics usually describes the behaviour of visible, ultraviolet, and infrared light. Because light is an electromagnetic wave, other forms of electromagnetic radiation such as X-rays, microwaves, and radio waves exhibit similar properties.
Attachment and optical probe
A medical monitoring system, such as an oximetry system, applies an attachment for securing an optical probe to a measurement site. The attachment has an elongated support with a first end and a second end, and a dedicated area in proximity of the first end. The dedicated area receives an optical probe and includes a material that is transparent for light emitted and received by the optical probe. The dedicated area mountably receives the optical probe on the material so that in use, the material is positioned between the optical probe and a surface of a measurement site. The optical probe may be factory-mounted to the dedicated area of the attachment as a ready-to-use sensor. In the alternative, the attachment may be available as an individual component, or as a part of a kit including the attachment and the optical probe.

Method to determine optical proximity correction and assist feature rules which account for variations in mask dimensions
InactiveUS6553559B2Photomechanical apparatusOriginals for photomechanical treatmentComputational physicsProcess window
Optical proximity correction (OPC) and assist feature rules are generated using a process window (PW) analysis. A reference pitch is chosen and the mask bias is found that optimizes the process window. This can be done using standard process window analysis or through a weighted process window (WPW) analysis which accounts for focus and dose distributions that are expected in a real process. The WPW analysis gives not only the optimum mask bias, but also the center focus and dose conditions for the optimum process centering. A series of other pitches and mask biases are then analyzed by finding the common process window with the reference pitch. For the standard PW analysis, a common process window is found. For the WPW analysis, the WPW is computed at the center focus and dose conditions found for the reference pitch. If mask or lens errors are to be accounted for, then multiple structures can be included in the analysis. Once the common process windows for the mask features of interest have been computed, functional fits to the data can be found. Once the functional forms have been found for each of the OPC parameters, the rules table can be determined by solving for the spacings of interest in the design.

Apparatus and method for injecting and modifying gas concentration of a meta-stable or atomic species in a downstream plasma reactor
InactiveUS20020029747A1Reduce lossesElectric discharge tubesChemical vapor deposition coatingGas passingActive matter
This invention provides an apparatus and method for injecting gas within a plasma reactor and tailoring the distribution of an active species generated by the remote plasma source over the substrate or wafer. The distribution may be made more or less uniform, wafer-edge concentrated, or wafer-center concentrated. A contoured plate or profiler is provided for modifying the distribution. The profiler is an axially symmetric plate, having a narrow top end and a wider bottom end, shaped to redistribute the gas flow incident upon it. The profiler is situated below an input port within the plasma reactor chamber and above the wafer. The method for tailoring the distribution of the active species over the substrate includes predetermining the profiler diameter and adjusting the profiler height over the substrate. A coaxial injector tube, for the concurrent injection of activated and non-activated gas species, allows gases (or gas mixtures) to be delivered in an axially symmetric manner whereby one gas can be excited in a high density RF plasma, while the other gas can be prevented from excitation and / or dissociation caused by exposure to the plasma or heated surfaces in the source apparatus. The gas admixture that is not to be excited or dissociated prior to contact with the wafer surface is shielded from direct exposure to the RF field surrounding the plasma confinement tube. The tube walls are also shielded from the infrared energy emitted from the plasma. The profiler is used in conjunction with the coaxial injector tube for redistributing the excited gases emerging from the injector tube, while allowing the non-excited gases to pass through its center.
