A METHOD OF PRODUCING A SURFACE MICROSTRUCTURE ON GLASS |
摘要 |
The invention provides a method to produce a microstructure on glass which is of excellent quality and allows for repeated use of a stamper. The method comprises heating the glass to a surface temperature corresponding to a log viscosity between about 13 to 8 poise, supporting the glass and impressing it with the stamper heated to about the same temperature as the glass so that a microstructure on the heated stamper will deform the surface of the glass to give a corresponding microstructure on the surface of the glass, which when separated from the stamper and cooled in a controlled manner gives the desired surface microstructure on the glass. The method is particularly suitable for forming tracking grooves on optical disk substrates. |
