ABSTRACT:
A flip chip mounting process wherein a semiconductor chip and a circuit substrate are electrically interconnected. The process includes the steps of preparing a semiconductor chip on which a first plurality of electrodes are formed and a circuit substrate on which a second plurality of electrodes are formed; supplying a composition onto a surface of the circuit substrate, such surface being provided with second plurality of electrodes; bringing the semiconductor chip into contact with a surface of said composition such that the first plurality of electrodes are opposed to the second plurality of electrodes; and heating the circuit substrate, and thereby electrical connections including a metal component constituting the metal particles dispersed in the composition are formed between the first plurality of electrodes and the second plurality of electrodes. Also, a thermoset resin layer is formed between the semiconductor chip and the circuit substrate.
