Technol. 2016;138(2): doi: / Figure Legend: Photographs of specially developed uniaxial tensile test equipment for thin films. The equipment is able to precisely apply tensile force to a film specimen. A CCD camera is set in the overhead of a specimen for tensile elongation measurement without contact. The equipment is set in a vacuum chamber to conduct quasi-static tensile tests and stress relaxation tests at intermediate temperatures without oxidation.

Technol. 2016;138(2): doi: / Figure Legend: Representative tensile stress–strain relations of the SU-8 specimens. It is found that both the test temperature and specimen thickness dependences on the stress–strain behaviors.
