摘要:
A method is provided for achieving an enhanced finish on a sputter target surface that results in good film uniformity, low particle counts, and little to no bum-in time. The method involves chemically etching the surface of the sputter target by immersing the surface one or more times in an etching solution, with intermediate rinsing steps. The result is a surface substantially free of mechanical deformation that exhibits a surface similar to a sputtered target with a surface roughness of 10-30 &mgr;in.

This invention provides a method of forming a metal wiring film excellent in EM resistance and low electric resistance. In a method of forming a wiring structure by filming and covering the surface of the insulating film of a substrate to be treated having a hole or groove formed thereon with a metallic material such as copper, aluminum, silver or the like, thereby filling the hole or groove inner part with the metallic material to form a wiring structure, the substrate to be treated is exposed to a high temperature under a high-pressure gas atmosphere after the continuous filming and covering with the metallic material along the inner surface profile of the hole or groove, whereby the surface diffusion phenomenon of the metallic material is promoted to reform the metal film into a film structure as the surface area of the metal film is minimized.

A linear aperture deposition apparatus and process are provided for coating substrates with sublimed or evaporated coating materials. The apparatus and process are particularly suited for producing flexible films having an optical interference coating with a very high surface thickness uniformity and which is substantially free of defects from particulate ejection of a source material. The apparatus includes a source box containing a source material, a heating element to sublime or evaporate the source material, and a chimney to direct the source material vapor from the source box to a substrate. A flow restricting baffle having a plurality of holes is positioned between the source material and the substrate to confine and direct the vapor flow, and an optional floating baffle is positioned on the surface of the source material to further restrict the vapor flow, thereby substantially eliminating source material spatter.

A thin film forming equipment and a method for forming thin films are provided which are capable of forming the thin film of high quality and of effectively preventing CVD material gas from leaking to surroundings at a low cost. The thin film equipment contains a substrate, a substrate holding device used to hold the substrate and a device used to provide an atmospheric gas to a surface of the substrate held by the substrate holding device, wherein an upper face of the substrate held by the substrate holding device and an upper face of the substrate holding device are almost on one plane.

A film is formed on the surface of a soft metal portion (2) such that the film contains phosphorus and either platinum or palladium, and further, at least one element having homogeneous solubility with platinum or palladium, with the content of the phosphorus being in a range of about 15 to 25 atomic %, or contains boron and iron with the content of the boron being in a range of from about 15 to 25 atomic %. Thus, a soft metal is made up by turning the film into a hard layer (3) made of an amorphous alloy.

A method of fabricating ternary TiNi-based alloys to achieve substantially higher phase-change transition temperatures in the resulting SMA materials and which have optimal thermo-mechanical properties. One target is provided which comprises the element Ti, a second target comprises the element Ni and a third target comprises an element which when combined with Ti and Ni can produce a shape memory alloy. The three targets are co-sputtered onto a substrate at rates which are controlled so that the sum of the percentage composition of the elements that are from the left side of the periodic table are substantially 50 atomic percent, and the sum of percentage composition of the elements that are from the right side of the periodic table comprise the remaining 50 atomic percent.

A low resistance magnetic tunnel junction with low resistance barrier layer and method of fabrication is disclosed. A first magnetic layer of material with a surface is provided and a continuous layer of material, e.g. aluminum, is formed on the surface of the first magnetic layer. The continuous layer of material is treated to produce a low resistance barrier layer of oxynitride material and a second magnetic layer is formed on the barrier layer of oxynitride material to complete the low resistance magnetic tunnel junction.
摘要:
A new class of light or reactive elements and monophase &agr;′-matrix magnesium- and aluminum-based alloys with superior engineering properties, for the latter being based on a homogeneous solute distribution or a corrosion-resistant and metallic shiny surface withstanding aqueous and saline environments and resulting from the control during synthesis of atomic structure over microstructure to net shape of the final product, said &agr;′-matrix being retained upon conversion into a cast or wrought form. The manufacture of the materials relies on the control of deposition temperature and in-vacuum consolidation during vapor deposition, on maximized heat transfer or casting pressure during all-liquid processing and on controlled friction and shock power during solid state alloying using a mechanical milling technique. The alloy synthesis is followed by extrusion, rolling, forging, drawing and superplastic forming for which the conditions of mechanical working, thermal exposure and time to transfer corresponding metastable &agr;′-matrix phases and microstructure into product form depend on thermal stability and transformation behavior at higher temperatures of said light alloy as well as on the defects inherent to a specific alloy synthesis employed. Alloying additions to the resulting &agr;′-monophase matrix include 0.1 to 40 wt. % metalloids or light rare earth or early transition or simple or heavy rare earth metals or a combination thereof. The eventually more complex light alloys are designed to retain the low density and to improve damage tolerance of corresponding base metals and may include an artificial aging upon thermomechanical processing with or without solid solution heat and quench and annealing treatment for a controlled volume fraction and size of solid state precipitates to reinforce alloy film, layer or bulk and resulting surface qualities. Novel processes are employed to spur production and productivity for the new materials.
