Disclosed is a method of brazing articles together to form at least one braze defined by complementarily curved faying surfaces on the articles, the faying surfaces each having at least one region of curvature comprising at least one point from which the surface curves in more than one direction, the method comprising the steps of: a) disposing between the complementarily curved faying surfaces at least one amorphous brazing alloy preform of complementary curvature at least in part to said at least one region of the complementarily curved faying surfaces to conform to the complementarily curved faying surfaces in said region; and b) heating the articles and at least one amorphous brazing alloy preform to a brazing temperature at which the amorphous brazing alloy flows and brazes. and brazing alloy preforms for use in such methods. Methods of forming an article comprising a curved surface from a sheet of an amorphous metal alloy are disclosed, by applying heat from a fluid to a sheet of the amorphous metal alloy to raise at least a portion of the sheet to a temperature above the glass transition temperature T.sub.g and below the crystallization temperature T.sub.x.

A material for Cu pillars is formed as cylindrical preforms in advance and connecting these cylindrical preforms to electrodes on a semiconductor chip to form Cu pillars. Due to this, it becomes possible to make the height/diameter ratio of the Cu pillars 2.0 or more. Since electroplating is not used, the time required for production of the Cu pillars is short and the productivity can be improved. Further, the height of the Cu pillars can be raised to 200 μm or more, so these are also preferable for moldunderfill. The components can be freely adjusted, so it is possible to easily design the alloy components to obtain highly reliable Cu pillars.

A brazing furnace (1) includes a preheating chamber (2) and a brazing chamber (3). The preheating chamber (2) includes: a vacuum pump (21) for reducing the pressure inside the preheating chamber (2) while a material to be processed (100) is housed therein; a preheating apparatus (22), which preheats the material to be processed (100) in a reduced-pressure atmosphere; and a gas introducing apparatus (23), which introduces inert gas into the preheating chamber (2) to restore the pressure inside the preheating chamber (2) after the preheating. The brazing chamber (3) includes: a gas-replacing apparatus (31), which introduces inert gas into the brazing chamber (3); and a main heating apparatus (32), which heats the material to be processed (100) to a brazing temperature while it is housed in the brazing chamber (3).
