摘要： A probe for use within a high voltage and high current electrical device is disclosed. The probe comprises an optical fiber, a substrate having a slot, and a photoluminescent material. The fiber has a first and second end and is configured to convey an activation light from the first to second end. A portion of the fiber is within the slot such that the slot receives the second end of the fiber. Emission of the photoluminescent material, as a function of temperature, is known. The photoluminescent material is disposed within at least a portion of the slot that faces the second end of the fiber so that they are in optical communication with each other. A change in intensity of a luminescent light emitted back into the fiber by the photoluminescent material when the activation light is conveyed by the fiber onto the photoluminescent material provides an indication of the integrity of the electrical device.

摘要： A system and method for efficiently performing timing characterization of regions of an integrated circuit. An integrated circuit has monitors distributed in different physical regions across its die. Each monitor includes timing characterization and self-test circuitry. This circuitry includes one or more tunable delay lines used during timing measurements. The circuitry verifies the tunable delay lines are defect free prior to the timing measurements. If defects are detected, but tunable delay lines may still be used, a scaling factor may be generated for a failing tunable delay line. The scaling factor may be used during subsequent timing measurements to maintain a high accuracy for the measurements. The timing measurements may determine a particular physical region of the die provides fast or slow timing values. The resulting statistics of the timing measurements may be used to change an operational mode of the IC in at least the particular region.

摘要： A characteristic of a surface is measured by illuminating the surface with optical radiation over a wide angle and receiving radiation reflected from the surface over an angle that depends on the extend of the illumination angle. An emissivity measurement is made for the surface, and, alternatively, if a reflectivity measurement is made, it becomes more accurate. One application is to measure the thickness of a layer or layers, either a layer made of transparent material or a metal layer. A one or multiple wavelength technique allow very precise measurements of layer thickness. Noise from ambient radiation is minimized by modulating the radiation source at a frequency where such noise is a minimum or non-existent. The measurements may be made during processing of the surface in order to allow precise control of processing semiconductor wafers, flat panel displays, or other articles. A principal application is in situ monitoring of film thickness reduction by chemical-mechanical-polishing (CMP).

摘要： Systems that measure temperatures of tissue during electrosurgery or laser therapy of the tissue or organs is provided. One system provides a pyrometer that measures infrared electromagnetic energy emitted by a surface of a tissue or organ thereby determining a sub-surface temperature of the tissue or organ. The system further has an energy generator and an ablation electrode or laser probe that delivers energy from the energy generator to a tissue or organ, responsive to a sub-surface temperature determined by the pyrometer. The pyrometer can be calibrated using a luminescent material having known optical properties as a function of temperature. The luminescent material can be positioned on the surface of the tissue or organ or inserted directly into the tissue or organ using a catheter. Methods in which the surface or sub-surface temperature of the tissue is measured during therapy are also provided.
