  • Method for patterning a mold
    Patent number: 5348616
    Abstract: A mold substrate having a major surface is provided. A patterned masking layer is formed on the major surface of the mold substrate that exposes portions of the major surface of the mold substrate while other portions are covered by the patterned masking layer. The major surface of the mold substrate is etched, thereby removing exposed portions of the major surface of the mold substrate, and thus transferring the pattern from the patterned masking layer to the major surface of the mold substrate.
