Template material in the field region is then etched with the resist as a mask, forming a template with a recessed field region after the remaining resist is removed. It should be appreciated that the order of these etch steps can be reversed to obtain the same result. | 02-03-2011 |

20140212536 | CYLINDRICAL MASTER MOLD ASSEMBLY FOR CASTING CYLINDRICAL MASKS - Aspects of the present disclosure include a cylindrical master mold assembly having a cylindrical patterned component with a first diameter and a sacrificial casting component with a second diameter. The component with the smaller radius may be co-axially inserted into the interior of the component with the larger radius. Patterned features may be formed on the interior surface of the cylindrical patterned component that faces the sacrificial casting component. The sacrificial casting component may be removed once a cast polymer has been cured to allow the polymer to be released. It is emphasized that this abstract is provided to comply with the rules requiring an abstract that will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure. It is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims. | 07-31-2014 |
