摘要:
A substrate processing system for processing multiple substrates is provided and generally includes at least one processing platform and at least one staging platform. Each substrate is positioned on a substrate carrier disposed on a substrate support assembly. Multiple substrate carriers, each is configured to carry a substrate thereon, are positioned on the surface of the substrate support assembly. The processing platform and the staging platform, each includes a separate substrate support assembly, which can be rotated by a separate rotary track mechanism. Each rotary track mechanism is capable of supporting the substrate support assembly and continuously rotating multiple substrates carried by the substrate carriers and disposed on the substrate support assembly. Each substrate is thus processed through at least one shower head station and at least one buffer station, which are positioned at a distance above the rotary track mechanism of the processing platform. Each substrate can be transferred between the processing platform and the staging platform and in and out the substrate processing system.

Each substrate is positioned on a substrates support assembly disposed on the rotary track system and being processed through at least one shower head station and at least one buffer station, which are positioned atop the rotary track system of the substrate processing platform. Multiple substrates disposed on the substrate support assemblies are processed in and out the substrate processing platform. The substrate staging platform includes at least one dual-substrate processing station, each dual-substrate processing station includes two substrate support assemblies for supporting two substrates thereon.

A processing chamber having a plurality of movable substrate carriers stacked therein for continuously processing a plurality of substrates is provided. The movable substrate carrier is capable of being transported from outside of the processing chamber, e.g., being transferred from a load luck chamber, into the processing chamber and out of the processing chamber, e.g., being transferred into another load luck chamber. Process gases delivered into the processing chamber are spatially separated into a plurality of processing slots, and/or temporally controlled. The processing chamber can be part of a multi-chamber substrate processing system.

A flux-contained welding wire is provided wherein a conductive core wire can be disposed without any complicate manufacturing steps performed on a metal outer layer. Flux is filled inside of the metal outer layer. The conductive core wire is disposed nearly in the center of the flux without being supported by the metal outer layer. The flux contains 20-80 weight % of metal powder. A weight % of the weight of the flux to the weight of the welding wire per unit length is set in a range of 6.5-30 weight %. The weight % of the weight of the conductive core wire to the weight of the welding wire per unit length is set in a range of 1.5-15 weight %.
摘要:
A method for removing particles and residue that build up inside a substrate processing system during a substrate processing operation, without overetching system components, is described. One method includes the steps of: flowing an etchant gas comprising chlorine trifluoride (CIF.sub.3), diluted with an inert carrier gas, into a processing chamber after completion of the substrate processing operation. The parts of the system within the chamber with the greatest amount of build-up are preferentially heated to facilitate more extensive cleaning of those parts. Parts of the system within the chamber with less build up are protected from overetching by keeping them about 200.degree. C. cooler than the heavily-deposited parts. Heating the heavily-deposited chamber parts to a temperature of at least about 400.degree. C. allows using a lower concentration of etchant gas for the cleaning process than a lower temperature process would allow. The etchant gas reacts with both particles and residue in the chamber, reducing both particulate-related defects and deposition build-up. Another method includes blanketing lightly-deposited areas of the chamber with a nonreactive gas to displace and dilute the etchant gas from these areas for part of the cleaning process, while heavily-deposited areas are exposed to a higher concentration of the etchant gas for a longer period of time. The blanketing gas is turned off for another part of the cleaning process so that these areas are also cleaned.

A clad plate includes an aluminum plate and a hard metal plate joined together at side end surfaces thereof. Side end surfaces of an aluminum plate and a hard metal plate are jointed together via a nickel layer by pressure welding. A ridge and a groove formed in the side end surface of the aluminum plate are respectively engaged and joined, via the nickel layer, to a groove and a ridge formed in the side end surface of the hard metal plate, and an end portion of the nickel layer extends beyond the rear end portion of the side end surface of the aluminum plate and is jointed to the plate surface of the aluminum plate with the end portion exposed thereon. The average width W of the exposed portion of the nickel layer exposed on the plate surface is preferably from about 0.2 mm to about 1.5 mm.

Disclosed is a manufacturing method for a thermistor element having a step wherein a thermistor raw material powder formed from a metal oxide, an organic binder powder, and a solvent are mixed and kneaded to form a clay, a step wherein the clay is extrusion-molded by means of a molding die to form a rod-shaped, green molded body having multiple through-holes, a step wherein the rod-shaped green molded body is dried to form a rod-shaped dried molded body, a step wherein the rod-shaped dried formed body is cut to a prescribed length to form a cut molded body having through-holes, and a step wherein lead wires are introduced into the through-holes of the cut molded body and firing is then performed to form a metal oxide sintered body for thermistor use from the cut molded body.

A clad sheet comprising a metal substrate and a metal cladding layer laminated on at least one surface of said substrate, wherein said cladding layer-laminated surface of said substrate includes a hardened layer portion formed by melting and rapid solidification through laser beam irradiation. In intermediate layer may be interposed between the substrate and the cladding layer through like hardened layer portion. Lamination is made by cold-cladding layer elements after irradiating any one of layer elements with laser beam to produce strong bonding through uniform microcrack formed in the hardened layer portion of several micrometer thick. The clad sheets are useful for making IC lead frames, for which the substrate is conductor metal and the cladding layer is solder applied to partial area of the substrate. The irradiation and cladding process is carried out continuously with a reduced draft.
