A method of supporting a substrate disposed in a cassette, the method comprising:
- inserting a substrate into the cassette, wherein the cassette includes:
- a main shaft fixed to the cassette in a direction parallel to the substrate;
- a movable bar movable parallel to the main shaft;
- reference bars rotatably fitted to the main shaft for moving the movable bar back and forth;
- and
- a plurality of support bars each fixed to the movable bar supported on the main shaft having a length adjustable according to the back and forth movements of the movable bar;
- measuring a sag of the substrate inserted into the cassette;
- and
- adjusting a length of the plurality of support bars, wherein the plurality of support bars support the substrate.

A method of supporting a substrate disposed in a cassette, the method comprising:
- inserting a substrate into the cassette, wherein the cassette includes:
- a plurality of vertical frames on both sides of a substrate entrance storing substrates;
- a stopper at an opposite side of the substrate entrance stopping the substrate, each of the frames having a plurality of support bars;
- a main shaft fixed to the stopper in a direction parallel to the substrate;
- a movable bar movable parallel to the main shaft;
- a reference bar rotatably fitted to the main shaft and vertical thereto which moves the movable bars back and forth, the plurality of support bars being fixed to the movable bar and supported on the main shaft, where the plurality of support bars have a length adjustable according to the reference bar, wherein the main shaft and the movable bar move relative to each other and wherein the reference bar adjusts the movable bar thereby adjusting the plurality of support bars;
- measuring a sag of the substrate into the cassette;
- and
- adjusting a length of the plurality of supports bars, wherein the plurality of support bars support the substrate.
