  • Patent number: 9022645
    Abstract: A plasma processing apparatus and a temperature measuring method that may measure a temperature of an object in a processing chamber by a low-coherence interferometer without forming a hole in a holding stage or an upper electrode of the plasma processing apparatus, thereby performing a plasma process of a substrate with high precision and uniformity. The plasma processing apparatus is implemented by disposing a light source collimator outside of a light source window, disposing a light-receiving collimator outside of a light-receiving window, allowing a measurement light emitted from the light source collimator to pass through the light source window to be obliquely emitted to a surface of the object to be measured, and allowing the reflected measurement light to pass through the light-receiving window to be incident on the light-receiving collimator. The temperature of the object in the processing chamber may be measured by the low-coherence interferometer.

    Abstract: An apparatus and methods for characterizing the response of a particle to a parameter that characterizes an environment of the particle. A change is induced in the parameter characterizing the environment of the particle, where the change is rapid on a timescale characterizing kinetic response of the particle. The response of the particle is then imaged at a plurality of instants over the course of a period of time shorter than the timescale characterizing the kinetic response of the particle. The response may be detected by measuring a temperature jump or by measuring correlation and anticorrelation between probe parameters across pixels. More particularly, the particle may be a molecule, such as a biomolecule, and the environment, more particularly, may be a biological cell. The parameter characterizing the environment of the particle may be a temperature, and change may be induced in the temperature by heating a volume that includes the particle, either conductively or radiatively.

    Abstract: This disclosure describes systems, methods, and apparatuses for making a non-contact measurement of a substrate in a plasma processing chamber that accounts for stray blackbody radiation. In particular, a photocurrent is calculated that can be attributed to the stray blackbody radiation based upon a temperature of the stray blackbody radiation, a reflectance of a target substrate, and a temperature of the substrate. Knowing the photocurrent attributable to the stray blackbody radiation, a non-contact temperature measurement can be made, and the photocurrent attributable to the stray blackbody radiation can be subtracted out to arrive at a more accurate non-contact substrate temperature measurement.

Applying the method according to the invention, the radiation incidence window (or perhaps another optical element in the beam path) is heated up or cooled by activating an associated electric heating or cooling device. The resulting change ?Uw in the sensor signal U is detected, preferably in continuous fashion, as a function of the window temperature Tw and analyzed or verified for any deviation from an acceptable value or permissible range.

  • Patent number: 6781098
    Abstract: A heater controller for an oxygen sensor associated with a vehicle engine. The controller includes a start detect section, a restart determination section, and a heater delay control section. The start detect section detects whether the engine is started. The restart determination section determines whether the engine is restarted. The heater delay control section operates the heater to activate after a predetermined delay time, delayed from startup of the engine, that is set according to an engine water temperature. The operation of the heater is executed when the start detect section detects that the engine is started and the restart determination section determines that the engine is not restarted.

    Abstract: The invention relates to an infrared thermometer, especially an ear thermometer for measuring temperature, comprising an infrared sensor, a measuring tip which can be heated by a heating element, an actuating device which can be operated by a user, a control device and a display device. The invention also relates to a method for measuring temperature, especially by means of a radiation thermometer having a heatable measuring tip. Said control device switches off the heating element after the user has actuated an actuating device. After a certain amount of time, a plurality of temperature measurements are successively carried out, and the temperature to be displayed is determined from said measured temperatures or an error message is generated. At the latest, after a maximum measuring time has elapsed or after a maximum number of temperatures have been measured, the temperature to be displayed or an error message is displayed on the display device.

  • Publication number: 20040047394
    Abstract: A test wafer for use in wafer temperature prediction is prepared. The test wafer includes: first semiconductor layer formed in a crystalline state; second semiconductor layer formed in an amorphous state on the first semiconductor layer; and light absorption film formed over the second semiconductor layer. Next, the test wafer is loaded into a lamp heating system and then irradiating the test wafer with a light emitted from the lamp, thereby heating the second semiconductor layer through the light absorption film. Thereafter, a recovery rate, at which a part of the second semiconductor layer recovers from the amorphous state to the crystalline state at the interface with the first semiconductor layer, is calculated. Then, a temperature of the test wafer that has been irradiated with the light is measured according to a relationship between the recovery rate and a temperature corresponding to the recovery rate.

  • Publication number: 20030206573
    Abstract: A temperature sensor utilizing optical temperature measuring techniques is constructed to make firm contact with a surface whose temperature is being measured, an example application being the monitoring of semiconductor wafers or flat panel displays while being processed. A cap is mounted near but spaced apart from an end of a lightwave guide, with a resilient element that applies force of the cap against a surface whose temperature is being measured as the cap is urged toward the optical fiber end. An optical temperature sensing element, such as luminescent material or a surface of known emissivity, is carried within the cap. A bellows with a closed end conveniently serves as both the cap and the resilient element. An alternative temperature measuring device installs an optical temperature sensing material within a test substrate behind an optical window, and then views the sensing material through the window.

  • Patent number: 6632016
    Abstract: A method of stabilizing a clinical thermometer and the apparatus thereof are disclosed. The method comprises the steps of pre-heating the surrounding temperature to a pre-set temperature prior to using the clinical thermometer for measuring temperature; and providing compensational temperature by way of heat energy by a control circuit such that the surrounding temperature is maintained and stabilized at the pre-set temperature so as to avoid the change of the surrounding temperature from affecting the measured temperature. The stabilizing devices for a clinical thermometer comprises a clinical thermometer probe head which is a material capable of producing heat energy; and a heating controller connected to the probe head which provides cavity heating for the probe head prior to temperature measuring to the pre-set surrounding temperature, thereby the heating controller causes the surrounding temperature to maintain at a constant and stable temperature such that the precision of measuring is accurate.
