Abstract

This disclosure provides a wafer carrier comprising a housing and a door. The housing includes at least one center-of-gravity offset member protruding from an outer surface of the housing. The door is detachably connected to the housing to form a storage space including a plurality of bearing planes spaced apart along a height direction for supporting at least one wafer frame. Thus, the wafer carrier of this disclosure provides wafer frame guiding functionality and prevents damage to the products on the wafer frame caused by wafer frame misalignment when the door is connected to the housing.

Claims

1. A wafer carrier comprising: a housing including: at least one center-of-gravity offset member protruding from an outer surface of the housing; and a door detachably connected to the housing to form a storage space including a plurality of bearing planes spaced apart along a height direction for supporting at least one wafer frame.

2. The wafer carrier as claimed in claim 1, wherein the housing further comprises: a plurality of support tabs spaced apart from each other along the height direction and protruding from two inner sides of the housing, the support tabs on the two inner sides being aligned with each other to form the bearing planes.

3. The wafer carrier as claimed in claim 1, wherein each pair of adjacent carrier planes includes a spacing distance greater than a thickness of the at least one wafer frame.

4. The wafer carrier as claimed in claim 1, wherein the at least one center-of-gravity offset member is located on one side of the outer surface.

5. The wafer carrier as claimed in claim 4, wherein when the outer surface of the housing serves as a placement surface, the at least one wafer frame tilts toward an inclined direction of the at least one center-of-gravity offset member.

6. The wafer carrier as claimed in claim 4, wherein the number of the at least one center-of-gravity offset member is two, the two center-of-gravity offset members are spaced apart from each other and located on the side of the outer surface.

7. The wafer carrier as claimed in claim 1, wherein the door body includes: an anti-misalignment frame located on an inner surface of the door body, the anti-misalignment frame including a plurality of stop plates spaced apart along the height direction.

8. The wafer carrier as described in claim 7, wherein the bearing planes and the stop plates are arranged alternately.

9. The wafer carrier as claimed in claim 7, wherein a width distance between the inner surface of the door and the housing is greater than a spacing distance between each of the stops and the housing.

10. The wafer carrier as claimed in claim 7, wherein the door further comprises: a recess, the anti-misalignment bracket being located within the recess, and a distance between a bottom surface of the recess and the housing being greater than a spacing distance between each of the stops and the housing.
