摘要: A new method is provided for the interconnection of flip chips to a supporting substrate. The invention starts with a conventional first substrate, that serves as a semiconductor device support structure, over the surface of which a first pattern of contacts points has been provided. The invention then uses a second substrate, for instance a glass or quartz plate, and creates over the surface thereof a second pattern of solder bumps separated by solder non-wettable surfaces. The second pattern is a mirror image of the first pattern. By then overlying the first pattern of contact points with the second pattern of solder bumps, a step of reflow can be applied to the solder bumps, transferring the solder bumps from the second substrate to the contact points provided over the first substrate.

摘要: An under bump metallurgy (UBM) structure is described. Two UBM mask processes are utilized. First, a top layer of copper (Cu) and/or a middle layer of nickel-vanadium (NiV) or chrome-copper (CrCu) is personalized by standard photoprocessing and etching steps utilizing a bump based size mask. This is followed by patterning an underlying seed layer with a second, larger mask, thereby preventing damage to the aluminum cap and seed layer undercut during the etching process.

摘要: Low stress concentration solder bumps are created on a semiconductor wafer by the removal of metal oxides of under bump metallurgy, (UBM). The removal of the oxides from the circular edge of the UBM allow the solder of the solder bump to wet the sides of the UBM, mainly the plated portion, thereby resulting in a solder bump structure with a filled undercut. This results in a lower stress concentration solder bump structure. This solder bump structure is obtained after the solder bumps have been reflowed on the wafer.
