The invention relates to a method for applying soft solder to a mounting surface of a component, wherein a connecting means comprising a carrier layer and a soft solder layer formed by physical vapor deposition on the carrier layer is brought into mechanical contact between the soft solder layer and the mounting surface, such that a first bond strength between the soft solder layer and the mounting surface is greater than a second bond strength between the soft solder layer and the carrier layer. The connecting means is subsequently removed from the component so that the carrier layer releases from the soft solder layer in the area of the mounting surface and thus soft solder remains only at the mounting surface. |

Devices and methods of welding dissimilar materials are contemplated in which an adaptor is used in an intermediate position between the dissimilar materials. Most preferred adaptors are manufactured by friction stir welding from two dissimilar materials that are identical or similar to the dissimilar materials to be welded together. Therefore, coupling of dissimilar materials in the field via the adaptors is greatly simplified as conventional welding methods can now be employed. |

Each second electrode formed on a second main surface of a compound semiconductor layer of a light emitting device has an alloyed contact layer disposed contacting the second main surface, aimed at reducing contact resistance with the compound semiconductor layer, and a solder layer connecting the alloyed contact layer to the conductive support. The solder layer forms therein a Sn-base solder layer disposed on the alloyed contact layer side having a melting point lower than the alloyed contact layer, and a Au—Sn-base solder layer disposed contacting the Sn-base solder layer opposed to the alloyed contact layer side, containing total Au and Sn of 80% or more, and having a melting point higher than the Sn-base solder layer. This configuration can provide excellent reliability of bonding between the Au—Sn-base solder layer and the alloyed contact layer, and consequently less causative of delamination of the Au—Sn-base solder layer. |

A method of modifying the structure of workpiece (1) is provided. The method comprises a first step of causing relative movement between a power beam and the workpiece (1) so that a region (3) of the workpiece (1) is melted and the melted material displaced to form a projection (2) at a first location in the region (3) and a hole (4) at a different location in the region. The melted material is then allowed to at least partially solidify after which the first step is repeated one or more times, with the region corresponding to each repeat intersecting the region (3) of the first step. |
