  • Publication number: 20240379407
    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: 20240377263
    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.

  • Publication number: 20130279187
    Abstract: An LED rear warning lamp includes a deflector plate assembled at a rear side of an automobile and formed with an accommodating chamber in the interior. A lamp set in the accommodating chamber of the deflector plate is composed of a base, a transparent inner cap, an LED circuit board, a cover plate, a shade and a transparent lamp casing. The LED circuit board is closely attached to the cover plate and then reversely fixed with the transparent inner cap that has its inner lower side protuberantly provided with irregularly refractive patterns. Thus, when reverse light of LEDs is projected upon the refractive patterns of the transparent inner cap, the refractive patterns will refract the light to the transparent lamp casing to send out even and soft light for warning.
