Method of preparing aluminum oxide substrate |
| abstract |
The present invention discloses a method of preparing aluminum oxide substrate having the steps as follows: providing a aluminum plate or foil, performing a chemical treatment on one surface of the aluminum plate or foil to produce a layer of aluminum oxide on the surface, and separating the layer of aluminum oxide from the aluminum material by etching the other surface of the aluminum material with chemical solution, grinding residual aluminum material or cutting the aluminum material. |
