  • Publication number: 20240268057
    Abstract: An example assembly includes an equipment room, a cabinet fan module having fans, and a processor configured to execute logic. Temperature sensors are positioned in the air inlet channel and the equipment room. An electrical component having an air inlet area is also positioned in the equipment room. The logic causes the fans to operate at a predetermined speed, and compare a temperature in the air inlet channel with a temperature at the air inlet area. In response to determining that the temperature at the air inlet area is greater than the temperature in the air inlet channel plus a constant value, the operating speed of the fans is increased. Moreover, the operating speed of the fans is decreased in response to determining that the ambient temperature in the air inlet channel plus a constant value is greater than or equal to the temperature at the air inlet area.

  • Publication number: 20240072090
    Abstract: Various embodiments of the present disclosure are directed towards a stacked complementary metal-oxide semiconductor (CMOS) image sensor in which a pixel sensor spans multiple integrated circuit (IC) chips and is devoid of a shallow trench isolation (STI) structure at a photodetector of the pixel sensor. The photodetector and a first transistor form a first portion of the pixel sensor at a first IC chip. A plurality of second transistors forms a second portion of the pixel sensor at a second IC chip. By omitting the STI structure at the photodetector, a doped well surrounding and demarcating the pixel sensor may have a lesser width than it would otherwise have. Hence, the doped well may consume less area of the photodetector. This, in turn, allows enhanced scaling down of the pixel sensor.

  • Publication number: 20240038818
    Abstract: Some implementations described herein provide for techniques to form a biased backside deep trench isolation and grid structure for a backside illumination image sensor. The techniques include forming an array of backside deep trench isolation structures and a biasing-pad that electrically connects to the array of metal-filled backside deep trench isolation structures through the grid structure. The array of backside deep trench isolation structures, the grid structure, and the biasing-pad structure may reduce a likelihood of electrical cross-talk and/or oblique light cross-talk between the photodiodes of the backside illumination image sensor. In this way, a performance of the backside illumination image sensor may be improved. Such improvements may include a suppression of a dark current within the backside illumination image sensor, a reduction in a number of white pixels, and a reduction in cross-talk within the backside illumination image sensor.
