Method for mounting and heating a plurality of microelectronic components
First Claim
1. A method for heat treating a plurality of conductive interconnect structures attached to a substrate, the method comprising the steps of:
- providing a contactor comprising a substrate and a plurality of conductive interconnect structures;
placing the contactor in an oscillating electromagnetic field, the oscillating electromagnetic field heating the interconnect structures without substantially heating the substrate; and
maintaining the contactor in the oscillating electromagnetic field until each of the interconnect structures obtains a defined heat-treatment temperature substantially greater than an ambient temperature for a predetermined period of time sufficient to permanently change a mechanical operating property of the interconnect structures,further comprising tuning a frequency of the oscillating electromagnetic field to between about 10 MHz–
15 MHz.

Abstract
A method for heat-treating a plurality of microelectronic structures attached to a non-metallic substrate is disclosed. The method comprises the steps of: (a) placing the non-metallic substrate and the plurality of microelectronic structures in an oscillating electromagnetic field, whereby the plurality of microelectronic structures are heated by the oscillating electromagnetic field and the non-metallic substrate is essentially not heated by the oscillating electromagnetic field; (b) maintaining the non-metallic substrate and the plurality of microelectronic structures in the oscillating electromagnetic field until each of the plurality of microelectronic structures obtains a defined heat-treatment temperature substantially greater than an ambient temperature; (c) removing the non-metallic substrate and the plurality of microelectronic structures from the oscillating electromagnetic field; and (d) cooling the plurality of microelectronic structures to the ambient temperature.
