The through-holes (11) each have an interior surface including taper surfaces (11b, 11c) which are tapered as having an opening size progressively decreasing from a main surface (21) and an external connection surface (22) toward a minimum size hole portion (11a). The taper surfaces (11b, 11c) respectively form obtuse angles ?1, ?2 with the main surface (21) and the external connection surface (22). A semiconductor element mount (BL) includes an insulative member (2) cut out of the collective substrate (1). An imaging device (PE2) includes an imaging element (PE1) mounted in a region surrounded by a frame (4) which is bonded to the main surface (21) of the insulative member (2) and closed by a cover (FL).

  • Patent number: 7633169
    Abstract: A chip package structure comprises a carrier, a chip and an underfill. The chip has an active surface on which a plurality of bumps is formed. The chip is flip-chip bonded onto the carrier with the active surface facing the carrier, and is electrically connected to the carrier through the bumps. The underfill is filled between the chip and the carrier. A portion of the underfill near the chip serves as a first underfill portion. The portion of the underfill near the carrier serves as a second underfill portion. The Young's modulus of the first underfill portion is smaller than the Young's modulus of the second underfill portion. The second underfill portion can be optionally replaced with a selected encapsulation. The selected encapsulation covers the chip and the carrier around the chip.

  • Patent number: 7547975
    Abstract: A module with embedded semiconductor IC of the present invention includes a first resin layer, a second resin layer, post electrodes passing through the first and second resin layers, and a semiconductor IC mounted as embedded between the first resin layer and the second resin layer. Stud bumps are formed on land electrodes of the semiconductor IC and positioned with respect to the post electrodes. Owing to this positioning of the stud bumps formed on the semiconductor IC with respect to the post electrodes, the planar position of the stud bumps is substantially fixed. As a result, it is possible to use a semiconductor IC having a very narrow electrode pitch of 100 ?m or smaller, particularly of around 60 ?m.
