  • Publication number: 20250149485
    Abstract: A method of forming an integrated circuit structure includes forming a patterned passivation layer over a metal pad, with a top surface of the metal pad revealed through a first opening in the patterned passivation layer, and applying a polymer layer over the patterned passivation layer. The polymer layer is substantially free from N-Methyl-2-pyrrolidone (NMP), and comprises aliphatic amide as a solvent. The method further includes performing a light-exposure process on the polymer layer, performing a development process on the polymer layer to form a second opening in the polymer layer, wherein the top surface of the metal pad is revealed to the second opening, baking the polymer, and forming a conductive region having a via portion extending into the second opening.

  • Publication number: 20250081730
    Abstract: A display may include an array of pixels such as light-emitting diode pixels. The pixels may include multiple circuitry decks that each include one or more circuit components such as transistors, capacitors, and/or resistors. The circuitry decks may be vertically stacked. Each circuitry deck may include a planarization layer formed from a siloxane material that conforms to underlying components and provides a planar upper surface. In this way, circuitry components may be vertically stacked to mitigate the size of each pixel footprint. The circuitry components may include capacitors that include both a high-k dielectric layer and a low-k dielectric layer. The display pixel may include a via with a width of less than 1 micron.

  • Publication number: 20250040015
    Abstract: An information handling system includes keyboard backlights, an embedded controller, and a processor. The embedded controller communicates with the keyboard backlights. In response to an activate keyboard backlights signal, the embedded controller turns on the keyboard backlights. In response to a deactivate keyboard backlights signal, the embedded controller turns off the keyboard backlights. The processor communicates with the embedded controller. The processor determines whether an ultrasonic waveform is received. In response to the ultrasonic waveform being received, the processors provide the deactivate keyboard backlights signal to the embedded controller. In response to the ultrasonic waveform not being received, the processor provides the activate keyboard backlights signal to the embedded controller.
