THREE DIMENSIONAL WRITING AND DEVELOPING METHOD OF OPTICAL INFORMATION |
| 摘要 |
<p>The invention is related to the field of technical physics and can be used for writing and developing of optical information. A possibility of information writing in bulk using optical radiation induced inversion of semiconductor conductivity type is shown. Selective chemical etching is used to develop information, as a result of etching of one conductivity type semiconductor.</p> |
