  • Publication number: 20240147664
    Abstract: A flow guiding device in an immersion-cooled chassis of a server comprises at least one deflector located above a chip on a mainboard in the chassis, each deflector comprises a first end for mounting to the mainboard above the chip and a second end inclined away from the mainboard. The first end is immersed in coolant, the second end is higher than the first end; the deflector further comprises a hollow part including multiple through holes for interrupting upward movement vapor bubbles generated by the hot chip, which reduces probability of the vapor bubbles escaping from the coolant liquid and the chassis. A liquid-cooled chassis having the flow guiding device is also disclosed.

  • Publication number: 20180269107
    Abstract: A method of forming a semiconductor device includes following steps. First of all, plural mandrel patterns are formed on a target layer. Then, plural capping layers are formed to cover a top region and sidewalls of each of the mandrel patterns, respectively. Next, plural spacers are formed at two sides of each of the capping layers, respectively. Following these, a portion of the spacers and the capping layers covered on the top regions of the mandrel patterns are simultaneously removed, and the capping layers is then removed completely.
