  • Patent number: 11605555
    Abstract: A method includes forming a first protruding fin and a second protruding fin over a base structure, with a trench located between the first protruding fin and the second protruding fin, depositing a trench-filling material extending into the trench, and performing a laser reflow process on the trench-filling material. In the reflow process, the trench-filling material has a temperature higher than a first melting point of the trench-filling material, and lower than a second melting point of the first protruding fin and the second protruding fin. After the laser reflow process, the trench-filling material is solidified. The method further includes patterning the trench-filling material, with a remaining portion of the trench-filling material forming a part of a gate stack, and forming a source/drain region on a side of the gate stack.

  • Publication number: 20230060543
    Abstract: A temperature measuring apparatus for measuring a temperature of a substrate is described. A light emitting source that emits light signals such as laser pulses are applied to the substrate. A detector on the other side of the light emitting source receives the reflected laser pulses. The detector further receives emission signals associated with temperature or energy density that is radiated from the surface of the substrate. The temperature measuring apparatus determines the temperature of the substrate during a thermal process using the received laser pulses and the emission signals. To improve the signal to noise ratio of the reflected laser pulses, a polarizer may be used to polarize the laser pulses to have a S polarization. The angle in which the polarized laser pulses are applied towards the substrate may also be controlled to enhance the signal to noise ratio at the detector's end.

  • Patent number: 11543455
    Abstract: A circuit measuring device and a method thereof are provided. A voltage source supplies a common voltage such that a calibration current having a preset current value flows from a current-voltage converter to a final test machine. The current-voltage converter converts the calibration current into a calibration voltage. At this time, a voltage sensing component senses a voltage between an input terminal and an output terminal of the current-voltage converter to output sensed calibration data. The current-voltage converter converts a tested current outputted by a tested circuit into a tested voltage. At this time, the voltage sensing component senses the voltage between the input terminal and the output terminal of the current-voltage converter to output actual sensed data. When the final test machine determines that a difference between the sensed calibration data and the actual sensed data is larger than a threshold, the tested circuit is adjusted.
