    Abstract: An IC device (10) held on an IC carrier (24) is a double-sided electrode type BGA IC device (10) provided with bump electrodes (14) on a first surface of a package. The IC device has, on a second surface opposite the first surface, (a) a central protrusion (30), (b) a peripheral portion (32) lower than the protrusion by one step, and (c) upper electrodes (18) formed on the peripheral portion of the IC device. The IC carrier is provided with a frame (36), a cover (40), and a holding means (42). The frame forms a device reception space (38) for receiving the IC device. The cover can cover the upper electrodes while in contact with the periphery of the IC device held on the IC carrier. The holding means can hold the IC device on the IC carrier with the cover covering the upper electrodes of the IC device. The IC device can be set in an IC socket while being mounted on the IC carrier.

  • Patent number: 7846771
    Abstract: A carrier for a stacked-type semiconductor device includes an accommodating section for accommodating stacked semiconductor devices, guide portions guiding the stacked semiconductor devices, and grooves through which a fluid may flow to the accommodating section and to sides of the stacked semiconductor devices. These grooves facilitate the flow of gas or liquid on the sides of the accommodating sections, and it is thus expected that the flow of hot wind during the reflow process and cleaning liquid during the cleaning process can be facilitated. This improves the production yield and the cleaning effects. Holes for connecting the accommodating section to the outside may be provided at corners of the accommodating section. Gas may be guided from the lower side of the accommodating section, so that heat can be efficiently applied to the semiconductor devices and bonding failures therebetween can be reduced.

  • Publication number: 20090093085
    Abstract: A carrier structure for fabricating a stacked-type semiconductor device includes: a lower carrier that has laminated thin plates and has first openings for mounting first semiconductor packages thereon; and an upper carrier having second openings for mounting second semiconductor packages on the first semiconductor packages. The lower carrier composed of the laminated thin plates realizes an even plate thickness and reduces warps because stress is distributed to the thin plates. This results in an improved production yield. A pattern of the openings in the thin plates of the lower carrier may be formed by etching or electric discharging. The openings thus formed have reduced warps and burrs.
