  • Publication number: 20220139918
    Abstract: Novel three-dimensional DRAM structures are disclosed, together with methods of making the same. Each DRAM cell comprises a vertical transistor and a storage capacitor stacked vertically. Storage capacitors are arranged in a rectangular pattern in the array of DRAM cells. This arrangement improves the area efficiency of storage capacitors over honeycomb type. A first embodiment of the present disclosure uses cup-shaped storage capacitors. The exterior of the cup as well as the interior may contribute to the capacitance. In a second embodiment, a single capacitor pillar forms the internal electrode of each storage capacitor. A third embodiment employs double-pillar storage capacitors. Common to all embodiments are options to dispose contact plugs between vertical transistors and storage capacitors, dispose an etch-stop layer over the gate of vertical transistors, dispose one or more mesh layers for storage capacitors, and widen semiconductor pillars within available space in bit-line direction.

  • Publication number: 20220130973
    Abstract: Structures and methods that facilitate the formation of gate contacts for vertical transistors constructed with semiconductor pillars and spacer-like gates are disclosed. In a first embodiment, a gate contact rests on an extended gate region, a piece of a gate film, patterned at a side of a vertical transistor at the bottom of the gate. In a second embodiment, an extended gate region is patterned on top of one or more vertical transistors, resulting in a modified transistor structure. In a third embodiment, a gate contact rests on a top surface of a gate merged between two closely spaced vertical transistors. Optional methods and the resultant intermediate structures are included in the first two embodiments in order to overcome the related topography and ease the photolithography. The third embodiment includes alternatives for isolating the gate contact from the semiconductor pillars or for isolating the affected semiconductor pillars from the substrate.

    Abstract: This specification discloses a quantum public-key cryptosystem. The quantum public-key cryptosystem may use two rotation operators R{circumflex over (n)}(?) and R{circumflex over (m)}(?) satisfying a cyclic evolution. The two rotation operators R{circumflex over (n)}(?) and R{circumflex over (m)}(?) do not have a commutation relation or an anti-commutation relation with each other. The commutation relation or the anti-commutation relation is established when either of the following conditions is satisfied: ?=2i?, ?=2j?, or {circumflex over (n)}·{circumflex over (m)}=1 (i, j=integer), and ?=(2k+1)?, ?=(2l+1)?, or {circumflex over (n)}·{circumflex over (m)}=0 (k, l=integer).
