摘要:
A capping film serving as an interconnect protective film formed on a surface of interconnect metal on a semiconductor substrate is formed after forming a catalyst layer for electroless plating under low oxygen concentration condition. A method for forming a capping film for protecting a surface of interconnect metal includes preparing a metal catalyst solution containing a metal element nobler than interconnect metal and having dissolved oxygen concentration of 7 ppm or less, bringing said metal catalyst solution into contact with a surface of interconnect metal to form a metal catalyst layer on the surface of the interconnect metal, and performing electroless plating to form a capping film on the surface of the interconnect metal.

The present invention relates to a lead-free bump with suppressed formation of voids, obtained by reflowing a plated film of Sn—Ag solder alloy having an adjusted Ag content, and a method of forming the lead-free bump. The lead-free bump of the present invention is obtained by forming an Sn—Ag alloy film having a lower Ag content than that of an Sn—Ag eutectic composition by plating and reflowing the plated alloy film.

An electrode having both of electronic conductivity and ionic conductivity is provided. An electrode provided with a mixed conductive carbon having electronic conductivity and ionic conductivity, the carbon containing an ion-dissociative group on the surface thereof. The use of a platelet-type or herringbone-type carbon fiber as the carbon material enables the introduction of ion-dissociative groups at a high density with continuity, whereby ion paths are effectively formed and an excellent ionic conductivity can be imparted, in addition to the electron conductivity inherent in the carbon fiber.

An image processing apparatus has a line memory for writing and reading image data of one line. A write/read controller controls writing and reading the image data of one line in and from the line memory. A white line determiner determines whether an image corresponding to image data of one line being written in the line memory is a white line. An image processor performs specified image processing on the image data of one line read from the line memory by the write/read controller. An image processing controller generates an operation clock used in the image processor and causes the image processor to perform the specified image processing for the image data of one line determined not to be a white line and stops generating the operation clock and reads white data from a white data storage for the image data of one line determined to be a white line.
摘要:
A lubricating oil feeding structure that permits an adequate amount of lubricating oil to be fed to those parts around the transmission while avoiding an excess supply of lubricating oil to the lubricating oil passage in the shaft of the transmission. The transmission has a space (as a recess to hold the shaft therein) in which is arranged the oil guide part. The oil guide part has the bottomed cylinder, with its one end opened, the flange that flares outward at the open end of the bottomed cylinder, and the oil holes that communicate between the inside and the outside of the bottomed cylinder. The oil guide part is arranged in the space in such a way that the flange comes into contact with the outer race of the bearing.

A plurality of fluids are accurately and quickly mixed such that a target characteristic is attained. A fluid control device is provided with flow channels (5, 7, 11,13) for allowing a plurality of to-be-mixed fluids to flow; flow channels (15, 17) for allowing a mixed fluid to flow; a pump (19) for shifting the fluids in the flow channels; flow rate adjusting units (11b, 13b) for respectively adjusting flow rates of a plurality of to-be-mixed fluids; a measuring unit (15a) for optically measuring a characteristic of the mixed fluid; and a control unit (21) that controls the flow rate adjusting units (11b, 13b) to adjust the flow rates of the to-be-mixed fluids based on a result of the measurement of the measuring unit (15a), such that the mixed fluid attains a target characteristic.
