Process for producing oriented inorganic crystalline film, and semiconductor device using the oriented inorganic crystalline film
ActiveUS20090152506A1Orientation can be controlledLow costFrom gel stateFrom solid stateOrganic solventDevice material
In a process for producing an oriented inorganic crystalline film, a non-monocrystalline film containing inorganic crystalline particles is formed on a substrate by a liquid phase technique using a raw-material solution which contains a raw material and an organic solvent, where the inorganic crystalline particles have a layered crystal structure and are contained in the raw material. Then, the non-monocrystalline film is crystallized by heating the non-monocrystalline film to a temperature equal to or higher than the crystallization temperature of the non-monocrystalline film so that part of the inorganic crystalline particles act as crystal nuclei.

Sequential method for depositing a film by modulated ion-induced atomic layer deposition (MII-ALD)
InactiveUS6428859B1Faster efficient meanSimple methodVacuum evaporation coatingSputtering coatingSequential methodHigh density
The present invention relates to an enhanced sequential atomic layer deposition (ALD) technique suitable for deposition of barrier layers, adhesion layers, seed layers, low dielectric constant (low-k) films, high dielectric constant (high-k) films, and other conductive, semi-conductive, and non-conductive films. This is accomplished by 1) providing a non-thermal or non-pyrolytic means of triggering the deposition reaction; 2) providing a means of depositing a purer film of higher density at lower temperatures; and, 3) providing a faster and more efficient means of modulating the deposition sequence and hence the overall process rate resulting in an improved deposition method. It is emphasized that this abstract is provided to comply with the rules requiring an abstract that will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure. It is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims.

Methods and compositions for culturing a biological tooth
Tooth tissues include the pulp mesenchyme that forms the dentin and an epithelium that is responsible for enamel formation. Cells from these tissues were obtained from porcine third molars and were seeded onto a biodegradable scaffold composed of a polyglycolic acid—polylactic acid copolymer. Cell polymer constructs were then surgically implanted into the omentum of athymic nude rats so that the constructs would have a blood supply and these tissues were allowed to develop inside the rats. Infrequently, columnar epithelial cells were observed as a single layer on the outside of the dentin-like matrix similar to the actual arrangement of ameloblasts over dentin during early tooth development. Developing tooth tissues derived from such cell polymer constructs could eventually be surgically implanted into the gum of an edentulous recipient where the construct would receive a blood supply and develop to maturity, providing the recipient with a biological tooth replacement.

Methods, systems, and apparatus for atomic-layer deposition of aluminum oxides in integrated circuits
InactiveUS20030207032A1Small volumeConsumes less gasPretreated surfacesChemical vapor deposition coatingProduct gasIntegrated circuit layout
Integrated circuits, the key components in thousands of electronic and computer products, are generally built layer by layer on a silicon substrate. One common layer-formation technique, known as chemical-vapor deposition (CVD), produces uneven layers and covers vertical surfaces poorly. An emergent technique, atomic-layer deposition, overcomes these shortcomings, but has others, such as slow deposition rates and longer than desirable cycle times, particularly as applied to deposition of aluminum oxide. Accordingly, the inventors devised unique atomic-layer deposition systems, methods, and apparatus suitable for aluminum-oxide deposition. One exemplary system includes an outer chamber, a substrate holder, and a gas-distribution fixture that engages or cooperates with the substrate holder to form an inner chamber within the outer chamber. The inner chamber has a smaller volume than the outer chamber, which ultimately requires less time to fill and purge and thus promises to reduce cycle times for deposition of materials, such as aluminum oxide.

The invention includes atomic layer deposition methods of depositing an oxide on a substrate. In one implementation, a substrate is positioned within a deposition chamber. A first species is chemisorbed onto the substrate to form a first species monolayer within the deposition chamber from a gaseous precursor. The chemisorbed first species is contacted with remote plasma oxygen derived at least in part from at least one of O2 and O3 and with remote plasma nitrogen effective to react with the first species to form a monolayer comprising an oxide of a component of the first species monolayer. The chemisorbing and the contacting with remote plasma oxygen and with remote plasma nitrogen are successively repeated effective to form porous oxide on the substrate. Other aspects and implementations are contemplated.
