Abstract:
A mask (stencil) having cells (openings) is disposed on a surface of a heater stage, and is then filled (printed) with solder paste. Then a substrate is assembled to the opposite side of the mask. Then the solder paste is reflowed. This may be done partially inverted. Then the mask is separated from the substrate, either before or after cooling. Solder balls are thus formed on the substrate, which may be a semiconductor wafer. A biased chuck urges the substrate into intimate contact with the mask. A method for printing the mask with solder paste is described. Methods of forming high aspect ratio solder bumps (including balls and reflowable interconnect structures) are described.

Each of the first strip and the second strip of the connection member is exposed on a corresponding one of the two major surfaces extending around the through-hole of the frame member. The first strip and the second strip extend in a direction in which the connection members face each other with the through-hole therebetween, and the opposed ends of the middle strip are continuously connected to an end of the first strip and an end of the second strip on the side adjacent to the through-hole. The middle strip extends through the inside of the frame member.
