PROBLEM TO BE SOLVED: To provide a packaging method for electronic components that allows an adhesive to be evenly disposed on a surface of a supporting substrate, such as a wiring substrate, on which electronic components are firmly fixed in response to pneumatic discharged from a semiconductor bonding tool for firmly fixing electronic components on the substrate using the adhesive. SOLUTION: As a method for packaging electronic components onto a supporting substrate 10, the present invention provides an adhesive disposition step for disposing an adhesive 12 to multiple places S1 to S5 on the supporting substrate 10 where electronic components are mounted and an electronic component mounting step for firmly fixing the electronic components by use of a suction tool to the mounting places S1 to 5 in a predetermined order through the adhesive 12. In the above adhesive disposition step, the volume centroid of adhesives 12-2 to 12-5 disposed at mount places S2 to S5 where an electronic component is mounted in the N-th order is made to be inclined in response to a deformed part owing to pneumatic blown off from the suction tool when an electronic component is mounted at the mount place S1 where an electronic component is mounted before the N-1th order.

PROBLEM TO BE SOLVED: To provide a manufacturing method of a semiconductor device for not propagating cracking and chipping generated at an outer peripheral edge to the inside when thinning a semiconductor wafer by back surface grinding. SOLUTION: On a semiconductor substrate 10 provided with a first surface 10a where the semiconductor device 12 is formed and a second surface 10b on the opposite side of the first surface, a recess 14 is formed in an outer peripheral region where the semiconductor device 12 is not formed on the first surface 10a. The second surface 10b of the semiconductor substrate 10 is ground and the semiconductor substrate 10 is thinned. Since the recess 14 is formed, the thickness of the semiconductor substrate 10 at the position of the recess 14 after grinding it from the side of the second surface 10b is extremely small. Or, the semiconductor substrate 10 is separated at the recess 14 by grinding from the side of the second surface 10b. COPYRIGHT: (C)2007,JPO&INPIT

PROBLEM TO BE SOLVED: To prevent that a passive component is brought into contact with a die pad in a semiconductor device, constituted by connecting a semiconductor chip and the passive component with bonding wires, wherein the passive component is mounted via insulating paste-like adhesives on the die pad mounting the semiconductor chip. SOLUTION: After applying a first insulating adhesive on the die pad, the first insulating adhesive is made to harden. On the hardened first insulating adhesives, a second insulating adhesive is applied further so that the passive component may be attached fixedly. Even if stress is added at the time of arranging the passive component on the die pad, passive component is prevented from coming into direct contact with the die pad due to the first insulating adhesive. Then, the connection is carried out between the electrode pad of the semiconductor device on the die pad and the terminal of the passive component by wire bonding. COPYRIGHT: (C)2007,JPO&INPIT
