Long strip-shaped wafer carrier disk

Abstract

This invention relates to a long strip-shaped wafer carrier, which includes a base and a support portion for carrying multiple long strip-shaped wafers. The support portion is formed on the top of the base, and the top surface of the support portion has multiple loading slots with upward openings. Each sidewall of each loading slot protrudes to form at least one positioning unit. Multiple long strip-shaped wafers can be respectively placed in the multiple loading slots, and the positioning units in the corresponding loading slots can respectively abut against the outer peripheral surface of the long strip-shaped wafer. This invention allows the long strip-shaped wafer carrier to abut against the outer peripheral edge of the long strip-shaped wafer through point contact between the positioning units in each loading slot and the long strip-shaped wafer, thereby significantly reducing the contact area with the long strip-shaped wafer while providing a good positioning effect, so as to avoid the long strip-shaped wafers from slipping during transportation and avoid friction to generate dust such as chips.

Claims

1. A strip-shaped wafer carrier disk for carrying a plurality of strip-shaped wafers, the strip-shaped wafer carrier disk comprising: a base; and a carrier portion formed on the top of the base, the top surface of the carrier portion having a plurality of loading slots with upward openings, each sidewall of each loading slot having at least one positioning unit protruding therefrom, the plurality of strip-shaped wafers being respectively disposed in the plurality of loading slots, and the positioning units in the corresponding loading slots being respectively abutting against the outer peripheral surface of the strip-shaped wafers.

2. The elongated wafer carrier as described in claim 1, wherein the positioning units of each pair of opposite sidewalls of the loading slot are arranged opposite to each other.

3. The elongated wafer carrier as described in claim 1, wherein the elongated wafer carrier includes a stacking recess formed at the bottom of the base, the stacking recess enclosing a stacking space, the dimensions of the stacking space corresponding to the dimensions of the carrier.

4. The elongated wafer carrier as described in claim 2, wherein the elongated wafer carrier includes a stacking recess formed at the bottom of the base, the stacking recess enclosing a stacking space, the dimensions of the stacking space corresponding to the dimensions of the carrier.

5. The elongated wafer carrier as described in any one of claims 1 to 4, wherein an oriented notch is formed at one corner of the base.

6. The elongated wafer carrier as described in any one of claims 1 to 4, wherein the outer diameter of each positioning unit gradually decreases from bottom to top.

7. The elongated wafer carrier as described in claim 5, wherein the outer diameter of each positioning unit gradually decreases from bottom to top.
