Samsung patents 3D memory layout with protruding active patterns
Samsung has filed a patent application for a semiconductor memory device that arranges bit lines, word lines, and active patterns in a specific three-dimensional structure. The design features an active pattern with a main section and smaller protruding sections positioned between the main section and the word line to optimize the layout. This configuration aims to improve the physical arrangement of components within the memory chip.
In the filing’s own words
The present disclosure relates to a semiconductor device, and a semiconductor device according to embodiments includes a substrate, a bit line positioned on the substrate and extending in a first direction, a word line positioned on the bit line and extending in a second direction intersecting the first direction, an active pattern extending in a third direction substantially perpendicular to the first direction and the second direction, and a cell capacitor positioned on the active pattern, the active pattern includes a first portion extending in the second direction, and a plurality of second portions protruding from the first portion in a first direction and positioned between the first portion and the word line.
What exactly they claim (claim 1)
1. A semiconductor device comprising: a substrate, a bit line positioned on the substrate and extending in a first direction, a word line positioned on the bit line and extending in a second direction intersecting the first direction, an active pattern extending in a third direction substantially perpendicular to the first direction and the second direction, and a cell capacitor positioned on the active pattern, wherein the active pattern includes the following: a first portion extending in the second direction, and a plurality of second portions protruding from the first portion in a first direction and positioned between the first portion and the word line.
