Patent ID: 7863094

Claim:
A method for removing bubbles from an adhesive layer of a semiconductor chip package, comprising the steps of: (a) attaching at least one first semiconductor chip on an upper surface of a base plate by the adhesive material; (b) placing the base plate with the first semiconductor chip attached thereto in a processing tank before the adhesive material starts curing or becomes fully cured; (c) setting the processing tank to a predetermined temperature and a predetermined pressure for a predetermined period of time; (d) expelling bubbles in the adhesive material, at an interface between the adhesive layer and the base plate, and at an interface between the adhesive layer and the first semiconductor chip from at least one fringe of the adhesive material; (e) taking out the base plate and the first semiconductor chip attached thereto from the processing tank; (f) coating a layer of the adhesive material on a lower surfaces of at least one second semiconductor chip, and attaching the second semiconductor chip to an upper surface of the first semiconductor chip, so as to stack the second semiconductor chip on the first semiconductor chip and form a semi-finished product; placing the semi-finished product in the processing tank; repeating the above steps (b), (c), and (d) to remove bubbles from the adhesive material coated on the lower surface of the second semiconductor chip; and then, taking out the semi-finished product from the processing tank; and (g) repeating the above step (f) to sequentially stack another semiconductor chip on the second semiconductor chip.
