    摘要: An improved magnetoresistive memory device has a reduced distance between the magnetic memory element and a conductive memory line used for writing to the magnetic memory element. The reduced distance is facilitated by forming the improved magnetoresistive memory device according to a method that includes forming a mask over the magnetoresistive memory element and forming an insulating layer over the mask layer, then removing portions of the insulating layer using a planarization process. A conductive via can then be formed in the mask layer, for example using a damascene process. The conductive memory line can then be formed over the mask layer and conductive via.

    摘要: A novel method for forming electrodes in the fabrication of an MIM (metal-insulator-metal) capacitor, is disclosed. The method improves MIM capacitor performance by preventing plasma-induced damage to a dielectric layer during deposition of a top electrode on the dielectric layer, as well as by reducing or preventing the formation of an interfacial layer between the dielectric layer and the electrode or electrodes, in fabrication of the MIM capacitor. The method typically includes the patterning of crown-type capacitor openings in a substrate; depositing a bottom electrode in each of the crown openings; subjecting the bottom electrode to a rapid thermal processing (RTP) or furnace anneal step; depositing a dielectric layer on the annealed bottom electrode; depositing a top electrode on the dielectric layer using a plasma-free CVD (chemical vapor deposition) or ALD (atomic layer deposition) process; and patterning the top electrode of each MIM capacitor.

    摘要: A method for reducing leakage current in a semiconductor structure is disclosed. One or more dielectric layers are formed on a semiconductor substrate, on which at least one device is constructed. A hydrogen-containing layer is formed over the dielectric layers. A silicon nitride passivation layer covers the dielectric layers and the hydrogen-containing layer. The hydrogen atoms of the hydrogen-containing layer are introduced into the dielectric layers without being blocked by the silicon nitride layer, thereby reducing leakage current therein.

    摘要: An image sensor includes a double-microlens structure with an outer microlens aligned over an inner microlens, both microlenses aligned over a corresponding photosensor. The inner or outer microlens may be formed by a silylation process in which a reactive portion of a photoresist material reacts with a silicon-containing agent. The inner or outer microlens may be formed by step etching of a dielectric material, the step etching process including a series of alternating etch steps including an anisotropic etching step and an etching step that causes patterned photoresist to laterally recede. Subsequent isotropic etching processes may be used to smooth the etched step structure and form a smooth lens. A thermally stable and photosensitive polymeric/organic material may also be used to form permanent inner or outer lenses. The photosensitive material is coated then patterned using photolithography, reflowed, then cured to form a permanent lens structure.

    摘要: An atomic layer deposition method for forming a microelectronic layer employs a reactor chamber pressure of greater than about 500 mtorr and more preferably from about 20 to about 50 torr. By employing a reactor chamber pressure within the foregoing range, the microelectronic layer is formed with an enhanced deposition rate while employing the atomic layer deposition method, due to a gas phase chemical vapor deposition component to the atomic layer deposition method.
