摘要:
The present invention provides a coating 10 provided on a conductor 20, the coating 10 has a first layer 12 containing palladium and a second layer 14 containing gold from the conductor 20 side, the first layer 12 has a first region 31 on the conductor 20 side and a second region 32 arranged nearer to the second layer 14 than the first region 31, and the second region 32 has a higher phosphorus concentration than the first region 31.
摘要:
Material can be deposited directly onto a substrate by using a fluid applicator such as an inkjet printer to apply at least two fluids which react to give the desired material for a range of applications. Thus, multiples of a printing mechanism are used to deposit materials as reagents that react together to form products. The materials may also be advantageously deposited from multiple inkjet heads to prepare a wide range of reaction scenarios in the form of user-defined patterns which may be sequences of differing layers and possibly to build up thicker layers. Thus, a PCB could be printed by the inkjet printer by simply printing the metal salt and the reducing agent directly, instead of two colours from a conventional inkjet printer for example. To print a three dimensional article, a pair of fluids which react to give a precipate can be used instead. Repeated passes can then build up a desired shape. The two processes could be combined to produce composite devices such as electrical components.

There is a method and apparatus for plating in which electroless copper plating is performed in a contact hole and an interconnect trench on a minute scale of a semiconductor integrated circuit device, and a plating structure. Organic material originated from an organic gas carried over from the preceding step is removed from the inner surface of a blind hole, thereafter the surface of the barrier layer (7) is subjected to predetermined pretreatments comprising a hydroxylation treatment, a coupling treatment, a Pd colloidal solution treatment and the like, and following the pretreatments, electroless plating (8) with copper is effected desirably under influence of ultrasonic waves. Hence, a uniform, good quality plating layer (8) is formed inside and outside the hole and a CMP processing following the plating is performed with ease.

摘要:
Provided is a doped tin oxide that can be used as a chemical plating promoter in a method for selectively metallizing a surface of an insulating substrate. Also provided are a polymer composition that includes the doped tin oxide, a polymer molded body, an ink composition, and a method for selectively metallizing a surface of an insulating substrate. The doped tin oxide has a light color, and does not interfere with the color of the substrate while presetting thereof. The doped tin oxide has a strong ability of promoting chemical plating. Using the disclosed doped tin oxide as a chemical plating promoter, a continuous metal layer can be formed with a high plating speed, together with enhanced adhesivity between the metal layer and the insulating substrate.

摘要:
Die Erfindung betrifft ein Verfahren zur stromlosen Metallabscheidung in sehr gleichmäßiger Schichtdicke durch Versprühen eines wäßrigen Metallabscheidungsbads oderer mehrerer entsprechender Teilbäder auf ein Substrat, wobei das bzw. die Bäder im Augenblick des ersten Auftreffens auf das Substrat mit Wasser im Verhältnis von etwa 1 : 1 bis 1 : 20 verdünnt werden. Sobald aus dem so verdünnten Bad ein erster dünner Metallfilm abgeschieden ist, wird die Bad- bzw. Teilbäderkonzentration stufenweise oder in einem Schritt auf die übliche Konzentration erhöht.
