Abstract:
An integrated circuit containing a FeCap array. The FeCap array is at least partially surrounded on the sides by hydrogen barrier walls and on the top by a hydrogen barrier top plate. A method for at least partially enclosing a FeCap array with hydrogen barrier walls and a hydrogen barrier top plate.
Abstract:
One aspect of the invention provides a method of manufacturing a FeRAM semiconductor device having reduce single bit fails. This aspect includes forming an electrical contact within a dielectric layer located over a semiconductor substrate and forming a first barrier layer over the dielectric layer and the electrical contact. The first barrier layer is formed by depositing multiple barrier layers and densifying each of the barrier layers after its deposition. This forms a stack of multiple barrier layers of a same elemental composition. The method further includes forming a second barrier layer over the first barrier layer and forming a lower capacitor electrode, a ferroelectric dielectric layer over the lower capacitor, and forming an upper capacitor electrode over the ferroelectric dielectric layer. A device made by this method is also provided herein.

Abstract:
A planar integrated MEMS device has a piezoelectric element on a dielectric isolation layer over a flexible element attached to a proof mass. The piezoelectric element contains a ferroelectric element with a perovskite structure formed over an isolation dielectric. At least two electrodes are formed on the ferroelectric element. An upper hydrogen barrier is formed over the piezoelectric element. Front side singulation trenches are formed at a periphery of the MEMS device extending into the semiconductor substrate. A DRIE process removes material from the bottom side of the substrate to form the flexible element, removes material from the substrate under the front side singulation trenches, and forms the proof mass from substrate material. The piezoelectric element overlaps the flexible element.
