Abstract

` Method for fabricating an undercoated chip electrically interconnected to a substrate. The method includes the initial step of depositing a predetermined quantity of a liquid undercoat material onto the chip or the substrate. The method continues with the step of interconnecting the chip to the substrate so as to form an electrical interconnection bond therebetween. Finally, the method concludes with the step of heating, reflowing and curing the undercoat material during or after the step of electrically interconnecting the chip to the substrate.
