  • Patent number: 11837268
    Abstract: A configuration for efficiently placing a group of capacitors with one terminal connected to a common node is described. The capacitors are stacked and folded along the common node. In a stack and fold configuration, devices are stacked vertically (directly or with a horizontal offset) with one terminal of the devices being shared to a common node, and further the capacitors are placed along both sides of the common node. The common node is a point of fold. In one example, the devices are capacitors. N number of capacitors can be divided in L number of stack layers such that there are N/L capacitors in each stacked layer. The N/L capacitors are shorted together with an electrode (e.g., bottom electrode). The electrode can be metal, a conducting oxide, or a combination of a conducting oxide and a barrier material. The capacitors can be planar, non-planar or replaced by memory elements.

    Abstract: Various embodiments of the present disclosure are directed towards a method of forming a ferroelectric memory device. In the method, a pair of source/drain regions is formed in a substrate. A gate dielectric and a gate electrode are formed over the substrate and between the pair of source/drain regions. A polarization switching structure is formed directly on a top surface of the gate electrode. By arranging the polarization switching structure directly on the gate electrode, smaller pad size can be realized, and more flexible area ratio tuning can be achieved compared to arranging the polarization switching structure under the gate electrode with the aligned sidewall and same lateral dimensions. In addition, since the process of forming gate electrode can endure higher annealing temperatures, such that quality of the ferroelectric structure is better controlled.

  • Patent number: 11792998
    Abstract: A process integration and patterning flow used to pattern a memory array area for an embedded memory without perturbing a fabricating process for logic circuitries. The fabrication process uses a pocket mask (e.g., a hard mask) to decouple the etching process of a memory array area and non-memory area. Such decoupling allows for a simpler fabrication process with little to no impact on the current fabrication process. The fabrication process may use multiple pocket masks to decouple the etching process of the memory array area and the non-memory area. This fabrication process (using multiple pocket masks) allows to avoid exposure of memory material into a second pocket etch chamber. The process of etching memory material is decoupled from the process of etching an encapsulation material. Examples of embedded memory include dynamic random-access memory and ferroelectric random-access memory.

  • Patent number: 11723281
    Abstract: An ultra-large height top electrode for MRAM is achieved by employing a novel thin metal/thick dielectric/thick metal hybrid hard mask stack. Etching parameters are chosen to etch the dielectric quickly but to have an extremely low etch rate on the metals above and underneath. Because of the protection of the large thickness of the dielectric layer, the ultra-large height metal hard mask is etched with high integrity, eventually making a large height top electrode possible.

  • Patent number: 11715798
    Abstract: An MFMIS-FET includes a MOSFET having a three-dimensional structure that allows the MOSFET to have an effective area that is greater than the footprint of the MFM or the MOSFET. In some embodiment, the gate electrode of the MOSFET and the bottom electrode of the MFM are united. In some, they have equal areas. In some embodiments, the MFM and the MOSFET have nearly equal footprints. In some embodiments, the effective area of the MOSFET is much greater than the effective area of the MFM. These structures reduce the capacitance ratio between the MFM structure and the MOSFET without reducing the area of the MFM structure in a way that would decrease drain current.
