摘要: A thin film structure includes a first conductive layer, a dielectric material layer on the first conductive layer, and an upper layer on the dielectric material layer. The dielectric material layer including HfxA1-xO2 satisfies at least one of a first condition and a second condition. In the first condition the dielectric material layer is formed to a thickness of 5 nm or less and in the second condition the x in HfxA1-xO2 is in a range of 0.3 to 0.5.

摘要: Some embodiments include ferroelectric assemblies. Some embodiments include a capacitor which has ferroelectric insulative material between a first electrode and a second electrode. The capacitor also has a metal oxide between the second electrode and the ferroelectric insulative material. The metal oxide has a thickness of less than or equal to about 30 Å. Some embodiments include a method of forming an assembly. A first capacitor electrode is formed over a semiconductor-containing base. Ferroelectric insulative material is formed over the first electrode. A metal-containing material is formed over the ferroelectric insulative material. The metal-containing material is oxidized to form a metal oxide from the metal-containing material. A second electrode is formed over the metal oxide.

摘要: 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.

摘要: A ferroelectric memory cell (FeRAM) is disclosed that includes an active device (e.g., a transistor) and a passive device (e.g., a ferroelectric capacitor) integrated in a substrate. The transistor and its gate contacts are formed on a front side of the substrate. A carrier wafer can be bonded to the active device to allow the active device to be inverted so that the passive device and associated contacts can be electrically coupled from a back side of the substrate.

摘要: A semiconductor device includes a random access memory (RAM) structure and a dielectric layer. The RAM structure is over a substrate and includes a bottom electrode layer, a ferroelectric layer over the bottom electrode layer, and a top electrode layer over the ferroelectric layer. The dielectric layer is over the substrate and laterally surrounds a lower portion of the RAM structure. From a cross-sectional view, the bottom electrode layer of the RAM structure has a lateral portion and a vertical portion, and the vertical portion upwardly extends from the lateral portion to a position higher than a top surface of the dielectric layer.

摘要: The memory bit-cell formed using the ferroelectric capacitor results in a taller and narrower bit-cell compared to traditional memory bit-cells. As such, more bit-cells can be packed in a die resulting in a higher density memory that can operate at lower voltages than traditional memories while providing the much sought after non-volatility behavior. The pillar capacitor includes a plug that assists in fabricating a narrow pillar.
