    Abstract: According to the invention, an improved analysis method for temperature monitoring of a hotplate (11) as a cooker with a temperature sensor (S) may be achieved by means of differentiating once over time and inverting the electronically interrogated temperature signal (T). The result of the inversion is raised to the power of ? to give an output value (A). This output value is used in further processing wherein, in the second processing, the output value is compared with stored values for an output value for defined events. The recording of the output value (A) occurs for a maximum time of up to 300 seconds after starting a cooking process, advantageously 60 to 120 seconds, and then said recording and analysis is terminated.

  • Patent number: 8173937
    Abstract: Flash lamps connected to short-pulse circuits and flash lamps connected to long-pulse circuits are alternately arranged in a line. The duration of light emission from the flash lamps connected to the long-pulse circuits is longer than the duration of light emission from the flash lamps connected to the short-pulse circuits. A superimposing of a flash of light with a high peak intensity from the flash lamps that emit light for a short time and a flash of light with a gentle peak from the flash lamps that emit light for a long time can increase the temperature of even a deep portion of a substrate to an activation temperature or more without heating a shallow portion near the substrate surface more than necessary. This achieves the activation of deep junctions without causing substrate warpage or cracking.

    Abstract: Temperature control in an RTP system can be improved by consideration of one or more witness structures different from the wafer (or other semiconductor object) being processed. For example, power coupling between the RTP heating system and witness structure can be used to adjust one or more control parameters, such as model definitions, that are used by the RTP system to control wafer heating. As another example, a stored trajectory of a desired witness structure temperature or other property can be used as a basis for control during a processing cycle. Thus, the witness structure may be controlled “closed-loop” while the wafer is heated “open-loop.” As a further example, a heat flux between the RTP heating system and witness structure can be used to determine radiant energy from the heating system that is incident on the witness structure. One or more control actions can be taken based on this incident energy.

  • Publication number: 20090166351
    Abstract: A device for heating a substrate with light from a flash lamp having a semiconductor switch connected in series to the flash lamp. After triggering of a trigger electrode of the flash lamp, a first drive signal and a second drive signal are output from a gate circuit. The time period when the semiconductor switch is on due to the second drive signal is longer than the time period that the semiconductor switch is on by the first drive signal. Then, the semiconductor switch is switched on and off by the first drive signal and the substrate temperature is increased to a temperature, which is lower than the desired temperature to be achieved, and is maintained a that temperature for a short time, after which the surface temperature of the substrate is increased to the desired target temperature.

  • Patent number: 7420140
    Abstract: A control system for an oven includes a first and a second temperature sensor, and a controller. The oven has a first cavity and a second cavity and includes, a first electrical heating element positioned within the first oven cavity, and a second electrical heating element positioned within the second oven cavity. The first temperature sensor is configured to detect a temperature within the first oven cavity, and the second temperature sensor is configured to detect a temperature within the second oven cavity. The controller is operatively coupled to the temperature sensors and the heating elements. The controller is configured to receive signals from the sensors and energize both the first and second heating elements by allowing energy to be supplied to only one of the first and second heating elements at a given time.
