Abstract: A method including forming an oxygen gettering layer on one side of an insulating layer of a deep trench capacitor between the insulating layer and a substrate, the oxygen gettering layer including an aluminum containing compound, and depositing an inner electrode on top of the insulating layer, the inner electrode including a metal.

Abstract: A surface of a semiconductor-containing dielectric material/oxynitride/nitride is treated with a basic solution in order to provide hydroxyl group termination of the surface. A dielectric metal oxide is subsequently deposited by atomic layer deposition. The hydroxyl group termination provides a uniform surface condition that facilitates nucleation and deposition of the dielectric metal oxide, and reduces interfacial defects between the oxide and the dielectric metal oxide. Further, treatment with the basic solution removes more oxide from a surface of a silicon germanium alloy with a greater atomic concentration of germanium, thereby reducing a differential in the total thickness of the combination of the oxide and the dielectric metal oxide across surfaces with different germanium concentrations.

Abstract: A method of polishing a wafer at the die level with a targeted slurry delivery system. The wafer is placed on a wafer carrier exposing the top side of the wafer, the wafer contains a die. The polishing apparatus will polish a portion of the die using a pad that is smaller than the die and the pad is located above the die. A slurry is applied to a portion of the die being polished. Embodiments of the invention provide multiple pads working on the same die.

Abstract: A high dielectric constant (high-k) gate dielectric for a field effect transistor (FET) and a high-k tunnel dielectric for a non-volatile random access memory (NVRAM) device are simultaneously formed on a semiconductor substrate. A stack of at least one conductive material layer, a control gate dielectric layer, and a disposable material layer is subsequently deposited and lithographically patterned. A planarization dielectric layer is deposited and patterned, and disposable material portions are removed. A remaining portion of the control gate dielectric layer is preserved in the NVRAM device region, but is removed in the FET region. A conductive material is deposited in gate cavities to provide a control gate for the NVRAM device and a gate portion for the FET. Alternately, the control gate dielectric layer may replaced with a high-k control gate dielectric in the NVRAM device region.

Abstract: Embodiments of the present invention provide structures and methods for controlling stress in semiconductor wafers during fabrication. Features such as deep trenches (DTs) used in circuit elements such as trench capacitors impart stress on a wafer that is proportional to the surface area of the DTs. In embodiments, a corresponding pattern of dummy (non-functional) DTs is formed on the back side of the wafer to counteract the electrically functional DTs formed on the front side of a wafer. In some embodiments, the corresponding pattern on the back side is a mirror pattern that matches the functional (front side) pattern in size, placement, and number. By creating the minor pattern on both sides of the wafer, the stresses on the front and back of the wafer are in balance. This helps reduce topography issues such as warping that can cause problems during wafer fabrication.
