Method for fabricating stacked chip package

摘要

A method for fabricating a stacked chip package comprises the steps of: (a) attaching a lower chip to a substrate or a lead frame; (b) electrically coupling the lower chip to the substrate or the lead frame; (c) providing a dummy chip with a film adhesive on a upper surface thereof; (d) attaching the dummy chip to the lower chip through an adhesive layer wherein a lower surface of the dummy chip is in contact with the adhesive layer; (e) attaching an upper chip to the dummy chip through the film adhesive; (f) electrically coupling the upper chip to the substrate or the lead frame; and (g) encapsulating the lower chip and the upper chip against a portion of the substrate or the lead frame with a molding compound. Since the dummy chip is bonded to the upper chip via a film adhesive, it is not necessary to monitor the thickness of the film adhesive after the upper chip is bonded to the dummy chip.
