METHOD AND APPARATUS FOR TRANSCRIPTING FINE PATTERNS
摘要:
In a method for transcripting fine patterns and an apparatus for transcripting fine patterns, the ingress of bubbles is prevented and patterns are transcripted with a high throughput by a relatively compact apparatus. For this purpose, a back surface of a stamper is vacuum sucked and the stamper is brought into close contact with a target of transcription with its surfaces coated with resist and pressure is applied thereto. At this time, the stamper is deformed into a spherical shape or bent to expand the close contact face from a central area to a peripheral area to prevent the ingress of air bubbles into between the target of transcription and the stamper.
