Lithographical patterning on the surface of a thin pipe is required for fabricating three-dimensional micro-parts. For this reason, a new exposure system for printing patterns on a cylindrical pipe by synchronous scan-projection exposure was developed. Using the exposure system, resist patterns with a width of 100 μm were printed on a surface of stainless-steel pipe with a diameter of 2 mm. The exposure time was 30 s. Printed resist pattern widths were measured in the axial and circumferential directions. As a result, pattern widths were almost uniform in both axial and circumferential directions. Judging from the experimental results, it was clarified that the patterning technology had a potential to be applied to fabrications of bio-medical devices and micro-parts.
