    Abstract: Capacitors and interconnect structures that couple transistors to one another include parallel stacked metal lines separated by dielectric layers. When capacitors and interconnect structures are combined, each top metal capacitor plate can be coupled to the nearest upper metal line by a through-via, while each bottom metal capacitor plate can be coupled directly to the nearest lower metal line without a via. When a back end of line (BEOL) cell includes multiple capacitors, and design rules require shrinking the cell dimensions, substituting an alternative design that has fewer through-vias can facilitate compaction of the BEOL cell. Similarly, placing capacitors in close proximity so that they can share through-vias can allow even further compaction.

    Abstract: Embodiments of mechanisms for forming a memory device structure are provided. The memory device includes a first gate stack structure. The first gate stack structure includes a first dielectric layer over a semiconductor substrate. The first gate stack structure also includes a first floating gate over the first dielectric layer, and the first floating gate has a tip corner. The first gate stack structure further includes a second dielectric layer conformally covering an upper surface and sidewalls of the first floating gate. The second dielectric layer has a substantially uniform thickness. In addition, the first gate stack structure includes a first control gate over the second dielectric layer and partially over the first floating gate.

    Abstract: Embodiments of mechanisms for forming a metal-insulator-metal (MIM) capacitor structure are provided. The metal-insulator-metal capacitor structure includes a substrate. The MIM capacitor structure also includes a CBM layer formed on the substrate, and the CBM layer includes a bottom barrier layer, a main metal layer and a top barrier layer. The MIM capacitor structure further includes a first high-k dielectric layer formed on the CBM layer, an insulating layer formed on the first high-k dielectric layer and a second high-k dielectric layer formed on the insulating layer. The MIM capacitor structure also includes a CTM layer formed on the second high-k dielectric layer, and the CBM layer includes a bottom barrier layer, a main metal layer and a top barrier layer.
