Abstract:
The present invention discloses flip-chip bonding method using an anisotropic adhesive polymer. The method includes applying an adhesive polymer solution containing metal particles dispersed therein onto a circuit substrate to form an adhesive polymer layer such that the adhesive polymer layer covers the metal particles; drying the adhesive polymer layer; and positioning an electronic element to be electrically connected to the circuit substrate on the dried adhesive polymer layer and causing dewetting of the polymer from the metal particles.
