  • Patent number: 12334333
    Abstract: A layer stack is formed over a conductive material portion located on a substrate. The layer stack contains a first silicon oxide layer, a silicon nitride layer formed by chemical vapor deposition, and a second silicon oxide layer. A patterned etch mask layer including an opening is formed over the layer stack. A via cavity extending through the layer stack and down to the conductive material portion is formed by isotropically etching portions of the layer stack underlying the opening in the patterned etch mask layer using an isotropic etch process. A buffered oxide etch process may be used, in which the etch rate of the silicon nitride layer is less than, but is significant enough, compared to the etch rate of the first silicon oxide layer to provide tapered straight sidewalls on the silicon nitride layer. An optical device including a patterned layer stack can be provided.

  • Patent number: 12288522
    Abstract: An electronic device includes a display and a sensor underneath the display. The display has a full pixel density region and a reduced pixel density region. Compared to pixels in the full pixel density region, pixels in the reduced pixel density region can be controlled using overdriven power supply voltages, overdriven scan control signals, different initialization and reset voltages, and can include capacitors and transistors with different physical and electrical characteristics. Gate drivers provide scan signals to pixels in the full pixel density region, whereas overdrive buffers provide overdrive scan signals to pixels in the reduced pixel density region. The pixels in the full pixel density region and the pixels in the reduced pixel density region can be controlled using different black level or gamma settings for each color channel and can be adjusted physically to match luminance, color, as well as to mitigate differences in temperature and aging impact.
