FABRICATION OF SUBSTRATE HAVING REVERSE TAPERED PATTERN BY ROLL PRINTING PROCESS

摘要

PURPOSE: A reverse-tapered pattern producing method using a roll printing process is provided to effectively form reverse-tapered patterns by using a roll printing process instead of an existing wet or dry etching process. CONSTITUTION: A reverse-tapered pattern producing method using a roll printing process is as follows. A cliche having pattern grooves is filled with paste. A printing roll having a blanket touches the cliche and is rolled on the cliche in an axial direction to transfer the paste from the engraved parts of the cliche to the blanket. The printing roller touches a release film having a release layer and is rolled on the release film in an axial direction to form paste patterns on the release layer. The release film with the release layer having the paste patterns touches a base material to form the paste patterns on an attachment enhancing layer of the base material. The release film is separated from the base material.
