    摘要: By using a mask 4, a first Group III nitride compound semiconductor layer 31 is etched, to thereby form an island-like structure such as a dot-like, striped-shaped, or grid-like structure, so as to provide a trench/post. Thus, without removing the mask 4 formed on a top surface of the upper layer of the post, a second Group III nitride compound layer 32 can be epitaxially grown, vertically and laterally, with a sidewall/sidewalls of the trench serving as a nucleus, to thereby bury the trench and also grow the layer in the vertical direction. The second Group III nitride compound layer 32 does not grow epitaxially on the mask 4. In this case, propagation of threading dislocations contained in the first Group III nitride compound semiconductor layer 31 can be prevented in the upper portion of the second Group III nitride compound semiconductor 32 that is formed through lateral epitaxial growth and a region having less threading dislocations can be formed in the buried portion of the trench.

    摘要: A first conductive electrode material is formed on a substrate. Chalcogenide comprising material is formed thereover. The chalcogenide material comprises AxSey. A silver comprising layer is formed over the chalcogenide material. The silver is irradiated effective to break a chalcogenide bond of the chalcogenide material at an interface of the silver comprising layer and chalcogenide material and diffuse at least some of the silver into the chalcogenide material. After the irradiating, the chalcogenide material outer surface is exposed to an iodine comprising fluid effective to reduce roughness of the chalcogenide material outer surface from what it was prior to the exposing. After the exposing, a second conductive electrode material is deposited over the chalcogenide material, and which is continuous and completely covering at least over the chalcogenide material, and the second conductive electrode material is formed into an electrode of the device.

    摘要: A selenidation reaction for bonding one or more active substrates to a base substrate is disclosed. A bonded-substrate is fabricated by forming a first multi-stacked layer of selenium and indium on a bonding surface of an active substrate and forming a second multi-stacked layer of selenium and indium on a mounting surface of a base substrate. The first and second multi-stacked layers are placed into contact with each other with substantially no pressure. Then the active substrate and the base substrate are bonded to each other by annealing them in an inert ambient to form an indium-selenium compound bond layer that adhesively bonds the substrates to each other. The annealing can occur at a lower temperature than prior wafer-bonding processes and the first and second multi-stacked layers can be deposited over a wide range of relatively low temperatures including room temperature. Additionally, tellurium can be added to the selenium of either one or both of the first and second multi-stacked layers to reduce the annealing temperature and to form an indium-selenium-tellurium compound bond layer that adhesively bonds the substrates to each other. Elemental compounds or amorphous compounds can be used for the materials of the first and second multi-stacked layers to form a polycrystalline or amorphous compound bond layer respectively. One advantage of the compound bond layer is that it can be dissolved using a selective wet etching material so that the active substrate and the base substrate can be non-destructively detached from each other.

    摘要: A method of forming sub-lithographic sized contact holes in semiconductor material, which includes forming layers of etch mask materials, and forming intersecting first and second trenches in the etch mask layers, where through-holes are formed completely through the etch mask layers only where the first and second trenches intersect. The first and second trenches are made by the formation and subsequent removal of very thin vertical layers of material. The width dimensions of the trenches, and therefore of the through-holes, are sub-lithographic because they are dictated by the thickness of the thin vertical layers of material, and not by conventional photo lithographic processes used to form those vertical layers of material. The sub-lithographic through-holes are then used to etch sub-lithographic sized contact holes in underlying semiconductor materials.

    摘要: Methods of forming metal-doped chalcogenide layers and devices containing such doped chalcogenide layers include using a plasma to induce diffusion of metal into a chalcogenide layer concurrently with metal deposition. The plasma contains at least one noble gas of low atomic weight, such as neon or helium. The plasma has a sputter yield sufficient to sputter a metal target and a UV component of its emitted spectrum sufficient to induce diffusion of the sputtered metal into the chalcogenide layer. Using such methods, a conductive layer can be formed on the doped chalcogenide layer in situ. In integrated circuit devices, such as non-volatile chalcogenide memory devices, doping of the chalcogenide layer concurrently with metal deposition and formation of a conductive layer in situ with the doping of the chalcogenide layer reduces contamination concerns and physical damage resulting from moving the device substrate from tool to tool, thus facilitating improved device reliability.
