  • Publication number: 20240188298
    Abstract: A method for fabricating a semiconductor memory device may include the steps of: forming a stacked body on a source layer by alternately stacking a plurality of interlayer dielectric layers and a plurality of gate sacrificial layers; forming a plurality of channel holes through the stacked body, the channel holes each having a lower end extended into the source layer; forming a channel layer along the surfaces of the channel holes, the channel layer including a first region formed in the stacked body and a second region formed in the source layer; and forming a channel passivation layer in the first region to scale down the thickness of the channel layer of the first region.

  • Publication number: 20240147098
    Abstract: A color matching circuit of an image sensor includes a receiving end configured to receive an analog pixel signal. The color matching circuit also includes a path controller including a first switch set configured to control current paths between a common node coupled to the receiving end and power sources and a second switch set configured to control signal paths between the common node and analog-to-digital converters, the path controller being configured to determine on-off states of switches included in the first switch set and the second switch set based on a color corresponding to the analog pixel signal. The path controller transfers the analog pixel signal to a target analog-to-digital converter determined depending on the on-off states of the switches, among the analog-to-digital converters.
