发明名称 Microelectronic connections with liquid conductive elements
摘要 A method of making a microelectronic assembly includes providing a first microelectronic element and a second microelectronic element with confronting, spaced-apart surfaces defining a space therebetween and providing one or more masses of a fusible conductive material having a melting temperature below about 150° C. in said space, whereby the fusible conductive masses connect the first and second microelectronic elements to one another. Next, a flowable material is introduced between the confronting surfaces of the first and second microelectronic elements and around the one or more fusible conductive masses and the flowable material is then cured to provide a compliant layer disposed between said confronting surfaces and intimately surrounding each fusible conductive mass. The fusible conductive masses are capable of electrically interconnecting the contacts on microelectronic elements confronting one another and/or conducting heat between confronting microelectronic elements.
