Abstract

A holding apparatus for a substrate cassette include a support base for holding the cassette with substrates. A tilting device is fixed to the support base for allowing the support base to rotate about a horizontal axis from a horizontal position, wherein top surfaces of the substrates are arranged upwardly, to an over vertical position, wherein the top surfaces of the substrates are arranged downwardly, by rotating the support base over 90 degrees. A storage method for a substrate cassette includes steps of storing a substrate in the cassette for substrates almost horizontally, fixing a cassette on a support base, and rotating the support base around a rotary shaft so that the substrate may rotate to the angle beyond 90 degrees.

Claims

1. A holding apparatus for a substrate cassette, comprising:

a cassette for storing a plurality of substrates;

a support base for holding the cassette; and

a tilting device fixed to the support base for allowing the support base to rotate about a horizontal axis from a horizontal position, wherein top surfaces of the substrates are arranged upwardly, to an over vertical position, wherein the top surfaces of the substrates are arranged downwardly, by rotating the support base over 90 degrees.

2. The holding apparatus for a substrate cassette according to claim 1, wherein the tilting device is provided with a rotary shaft elongating to the horizontal axis.

3. The holding apparatus for a substrate cassette according to claim 2, wherein the cassette comprises a floor plate, a top plate and side plates extending between the floor plate and the top plate, and the side plates are provided with supporting teeth protruded therefrom to support the substrates inserted through an opening revealing the teeth.

4. The holding apparatus for a substrate cassette according to claim 2, wherein the tilting device rotates the support base approximately 180 degrees around the rotary shaft.

5. The holding apparatus for a substrate cassette according to claim 1, wherein the support base holds the cassette by supporting a bottom and a side of the cassette.

6. The holding apparatus for a substrate cassette according to claim 5, wherein the support base includes a first support base supporting a bottom of the cassette, and a second support base supporting a side of the cassette.

7. The holding apparatus for a substrate cassette according to claim 5, wherein the rotary shaft is substantially parallel to an insertion direction of the substrates to the cassette.

8. The holding apparatus for a substrate cassette according to claim 1, wherein the support base holds the cassette by supporting a bottom and a back of the cassette.

9. The holding apparatus for a substrate cassette according to claim 8, wherein the support base includes a first support base supporting a bottom of the cassette, and a second support base supporting a back of the cassette.

10. The holding apparatus for a substrate cassette according to claim 5, wherein the rotary shaft is substantially perpendicular to an insertion direction of the substrates to the cassette.

11. A storage method for a substrate cassette, comprising the steps of:

storing substrates in a cassette for substrates almost horizontally;

fixing the cassette on a support base; and

rotating the support base around a rotary shaft until the substrate will rotate 90 degrees or more.

12. The storage method for a substrate cassette according to claim 11, wherein the cassette forms a box structure with a floor plate, a top plate and a plurality of supports, and stores a plurality of the substrates between the plurality of supports.

13. The storage method for a substrate cassette according to claim 12, wherein the tilting device can rotate the support base to approximately 180 degree around the rotary shaft.

14. The storage method for a substrate cassette according to claim 11, wherein the support base holds the cassette by supporting a bottom and a side of the cassette.

15. The storage method for a substrate cassette according to claim 14, wherein the tilting device is fixable where the support base is rotated in a direction of a side of the cassette.

16. The storage method for a substrate cassette according to claim 11, wherein the support base holds the cassette by supporting a bottom and a back of the cassette.

17. The storage method for a substrate cassette according to claim 16, wherein the tilting device is fixable where the support base is rotated in a direction of a back of the cassette.
