Description
FIELD OF THE INVENTION
[0001] The present invention relates to a carrier for wafer boxes,
and more particularly to an anti-shock carrier for wafer boxes.
BACKGROUND OF THE INVENTION
[0002] In general, there are two types of 12-inch front opening
wafer boxes. One is the front opening unified pod (FOUP) for the
pre-processing of the semiconductor fabrication, and the other is
the front opening shipping box (FOSB) for the post processing of
the semiconductor fabrication, such as the testing and packaging
etc. The front opening unified pod (FOUP) is applied to the indoor
transportation during the pre-processing, and the wafers usually
suffer less damages. However, the front opening shipping box (FOSB)
is applied to the outdoor transportation, and during the outdoor
transportation the wafers often suffer some damages.
[0003] During the outdoor transportation, the FOSB is usually put
on a hand-operated cart. Even though the hand-operated cart is
equipped with a shock absorber, the anti-shock effect is poor.
Please refer to FIG. 1, which is a schematic view showing an
anti-shock caster according to the prior art. The anti-shock caster
10 has the shock absorber 11 and the rolling wheel 12. The axle 13
of the rolling wheel 12 is vertically moved and vibrated along the
fillister 14 of the shock absorber 11. According to the anti-shock
caster 10, the anti-shock effect is only restricted within the
vertical direction (VD), and, inevitably, the horizontal vibration
would still cause the wafers' damages during the
transportation.
[0004] Usually the wafer boxes are packaged in a black or gray
vacuum bag for being transferred to the post processing of the
semiconductor fabrication. According to such a package fashion, it
is not easy to point out when and how the wafers are broken.
[0005] Therefore, how to provide the carrier with anti-shock
effects in both horizontal and vertical directions and how to
monitor the wafer boxes during the transportation have become the
major problems waiting to be solved in the industry. In order to
overcome the drawbacks in the prior art, a carrier for wafer boxes
is provided. In the particular invention, the problems of poor
anti-shock effect in horizontal direction and the rough
transportation are solved and it is also safe and convenient to
stabilize the wafer boxes in a carrier.
