The structure of a pillar-type capacitor is compared with that of a cylinder-type capacitor in Figure 5.[12,24] Buried cell array transistors (BCAT) are underneath those capacitors. The cylinder-type capacitor cell width occupies as much space as the thickness of its two lower electrodes, two upper electrodes, and four dielectric layers.
Pillar capacitors have the disadvantage of reduced surface area compared to that of cylinder-type capacitors. However, the pillar-type capacitors have a smaller cell size than cylinder-type capacitors, and therefore the integration density can be further increased.
This achievement opens up an alternative integration roadmap for DRAM capacitors, moving from the current cup-shape to a denser pillar-shape design. Current memory technologies, such as DRAM, SRAM, and NAND Flash, are encountering difficult challenges related to their continued scaling to and beyond the 16nm generation.
The capacitor structure evolves from a cylinder-type capacitor to a pillar-type capacitor for high-density DRAMs, as shown in Fig. 1 . Pillar capacitors have the disadvantage of reduced surface area compared to that of cylinder-type capacitors.
... large technology node enables the use of cylindrical capacitors to maximize the effective capacitor area. For sub-20-nm technology nodes, however, the cylindrical structure is no longer valid and pillar capacitors are utilized because of their small feature size (F < 20-40 nm) (Figure 3 a).
DRAM capacitors are composed of metal–insulator–metal thin films. In this review, we summarize experimental methods for development of high- k insulators and metal thin films for DRAM capacitors using the atomic layer deposition (ALD) process.

Design for manufacturing of 3D capacitors
All capacitors with the pillar shape are not enough robust and are very defective: with the high aspect ratio, the sticking phenomenon is global and is not limited to several structures. On these capacitor areas only few 3D structures are safe (see Fig. 15). Consequently there is no significant electrical result for this type of structure.
