An integrated underfilling process for attaching a chip / die having conductive solder bump contacts to a substrate. The process involves B-staging filled underfill on the chip / die, depositing a fluxing unfilled underfill onto the surface of the substrate, mating the chip / die with the B-staged underfill to the substrate and reflowing the assembled chip / substrate. The B-staged filled underfill reduces the coefficient of thermal expansion of the underfill fillet and the fluxing unfilled underfill removes metal oxide from the surface of the solder bump contacts and bond pads to promote the formation of reliable metallurgical joints.

Such a structure permits incorporation of remeltable layers for rework, test, or repair. It also allows incorporation of electrical redistribution layers. In one aspect, the chip and pre-coated encapsulant are placed at an angle to the substrate and brought into contact with the pre-coated substrate, then the chip and precoated encapsulant are pivoted about the first point of contact, expelling any gas therebetween until the solder bumps on the chip are fully in contact with the substrate. There is also provided a flip-chip configuration having a complaint solder / flexible encapsulant understructure that deforms generally laterally with the substrate as the substrate undergoes expansion or contraction. With this configuration, the complaint solder / flexible encapsulant understructure absorbs the strain caused by the difference in the thermal coefficients of expansion between the chip and the substrate without bending the chip and substrate.
