Abstract:
1. A method of packaging a chip, the method comprising: providing a chip and a base; applying adhesive pads to at least one of a side of the chip or a side of the base; performing a first heat-treatment to solidify the adhesive pads, the first heat-treatment being performed at a first temperature at which the adhesive pads solidify without losing adhesive properties; joining the chip and the base and aligning the chip to make it coplanar in relation to the base; after or while joining the chip and the base, exposing the adhesive pads to a second temperature at which the adhesive pads respectively bond with a previously not yet connected side; performing a second heat-treatment to cause the adhesive pads to set, the second heat-treatment being performed at a third temperature at which the adhesive pads completely solidify, whereby the chip is firmly connected to the base; and after performing the second heat-treatment, providing a molding compound to the chip and the base, such that the molding compound penetrates into intermediate spaces between the chip and the base.
