Abstract:
An assembly ( 101 ) comprising a semiconductor device ( 110 ) with solderable bumps ( 112 ); a substrate ( 120 ) with a layer ( 130 ) of a first insulating compound and an underlying metal layer ( 140 ) patterned in contact pads ( 141 ) and connecting traces ( 142 ), the insulating layer having openings ( 132 ) to expose the surface ( 142 a ) and sidewalls ( 142 b ) of underlying traces; the device bumps soldered onto the contact pads, establishing a gap ( 150 ) between device and top insulating layer; and a second insulating compound ( 160 ) cohesively filling the gap and the second openings, thereby touching the underlying traces, the second insulating compound having a higher glass transition temperature, a higher modulus, and a lower coefficient of thermal expansion than the first insulating compound.

Claim (Index 15):
The assembly of  claim 14  wherein the first insulating compound is a rigid polymer having a modulus typically in the range of 2 to 6 GPa at room temperature and a CTE in the range of 40 to 70 ppm/\u00b0 C. below the glass transition temperature of the material, and the second insulating compound is an epoxy-based polymer containing an inorganic filler material and having a modulus typically in the range of 6 to 11 GPa at room temperature and a CTE in the range of 20 to 40 ppm/\u00b0 C. below the glass transition temperature.
