  • SEMICONDUCTOR MEMORY DEVICE AND METHOD FOR MANUFACTURING THE SAME
    Publication number: 20240114674
    Abstract: A semiconductor memory device includes a substrate; a bit-line on the substrate and extending in a first direction; first and second channel patterns on the bit-line; the second channel pattern being spaced apart from the first channel pattern in the first direction; a first word-line between the first and second channel patterns and extending in a second direction that intersects the first direction; a second word-line between the first and second channel patterns, extending in the second direction, and being spaced apart from the first word-line in the first direction; capacitors on and connected to the channel patterns; wherein the first and second channel patterns include first and second metal oxide patterns sequentially on the bit-line, each of the first and second metal oxide patterns include an amorphous metal oxide, and a composition of the first metal oxide pattern is different from a composition of the second metal oxide pattern.
