    Abstract: In some embodiments, the present disclosure relates to an integrated chip. The integrated chip includes a logic region having a plurality of transistor devices disposed within a substrate, an embedded memory region having a plurality of memory devices disposed within the substrate, and a boundary region separating the logic region from the embedded memory region. The boundary region includes a first isolation structure having a first upper surface and a second upper surface below the first upper surface. The first and second upper surfaces are coupled by an interior sidewall overlying the first isolation structure. The boundary region further includes a memory wall arranged on the second upper surface and surrounding the embedded memory region, and a logic wall arranged on the first upper surface and surrounding the memory wall. The logic wall has an upper surface that is above the plurality of memory devices and the memory wall.

    Abstract: The present disclosure relates to a non-planar FEOL (front-end-of-the-line) capacitor comprising a charge trapping dielectric layer disposed between electrodes, and an associated method of fabrication. In some embodiments, the non-planar FEOL capacitor has a first electrode disposed over a substrate. A charge trapping dielectric layer is disposed onto the substrate at a position adjacent to the first electrode. The charge trapping dielectric layer has an “L” shape, with a lateral component extending in a first direction and a vertical component extending in a second direction. A second electrode is arranged onto the lateral component and is separated from the first electrode by the first component.

    Abstract: The present disclosure relates to a method of forming an integrated circuit (IC). In some embodiments, a substrate is provided comprising a memory region and a logic region. A sacrificial logic gate electrode is formed within the logic region together with a control gate electrode or a select gate electrode within the memory region by patterning a control gate layer or a select gate layer. A first inter-layer dielectric layer is formed between the sacrificial logic gate electrode and the control gate electrode or the select gate electrode. A hard mask is formed over the first inter-layer dielectric layer to cover the memory region and to expose the sacrificial logic gate electrode within the logic region. The sacrificial logic gate electrode is replaced with a high-k gate dielectric layer and a metal layer to form a metal gate electrode within the logic region.

    Abstract: The present disclosure relates to an integrated circuit (IC) that includes a HKMG hybrid non-volatile memory (NVM) device and that provides small scale and high performance, and a method of formation. In some embodiments, the integrated circuit includes a memory region having a NVM device with a pair of control gate electrodes separated from a substrate by corresponding floating gates. A pair of select gate electrodes are disposed at opposite sides of the pair of control gate electrodes. A logic region is disposed adjacent to the memory region and has a logic device with a metal gate electrode disposed over a logic gate dielectric and having bottom and sidewall surfaces covered by a high-k gate dielectric layer. The select gate electrodes or the control gate electrodes comprise metal and have bottom and sidewall surfaces covered by the high-k gate dielectric layer.
