Samsung patents chip design that extends memory cells over bitlines
Samsung has been granted a patent for a semiconductor structure where the active part of a memory cell is longer than the wire it sits on. This design places a back gate electrode and a wordline on opposite sides of the active area to manage the flow of data. The filing describes a specific geometric arrangement for these components on a chip substrate.
In the filing’s own words
A semiconductor device may include a substrate, a bitline extending in a first direction on the substrate, and an active pattern on the bitline. The semiconductor device may include a back gate electrode extending beside one side of the active pattern in a second direction perpendicular to the first direction across the bitline, and a wordline extending in the second direction beside the other side of the active pattern. A length of the active pattern in the second direction may be greater than a length of the bitline in the second direction.
What exactly they claim (claim 1)
1. A semiconductor device comprising: a substrate; a bitline extending in a first direction on the substrate; an active pattern on the bitline; a back gate electrode extending, beside a first side of the active pattern, in a second direction perpendicular to the first direction across the bitline; and a wordline extending in the second direction beside a second side of the active pattern, the second side opposite to the first side, wherein a length of the active pattern in the second direction is greater than a length of the bitline in the second direction.
