    • 一種導線架上覆晶半導體封裝結構,其係包含有複數個引腳、至少一晶片及一封膠體,該些引腳之上表面內端係為凸塊接合區,該些引腳之下表面外端係形成有複數個外接區,該些引腳係形成有至少一阻銲凹陷部,該阻銲凹陷部係鄰接該些凸塊接合區,其係可供該封膠體填充,該阻銲凹陷部係具有倒「Ω」形截面為佳,以阻止該覆晶晶片之凸塊過度潤溼擴散至該些引腳之其它部位,並以該封膠體係填充於該阻銲凹陷部,以達到穩固該些引腳之內端。 A semiconductor package with flip chip on leadframe comprises a plurality of leads, at least a chip and a molding compound. The leads have a plurality of bump-bonding regions on upper surfaces at inner ends thereof and have a plurality of outer connecting regions on lower surfaces at outer ends thereof. At least a solder-resist concave portion is formed on upper surfaces of the leads adjacent to the flip-chip bonding regions for filling in the molding compound. The solder-resist concave portion preferably has an upside-down "Ω"-shaped profile for preventing other portions of the leads from being over-wetted and spread by bumps of the chip. Because that the solder-resist concave portion is filled with the molding compound, the inner ends of the leads are fixed well.
