Ultrahigh resolution of calixarene negative resist in electron beam lithography
TL;DR: In this paper, a nonpolymer material, calixarene derivative (hexaacetate p‐methnylcalix[6]arene) was tested as a high-resolution negative resist under an electron beam lithography process.
Journal ArticleDOI
Nanometer‐scale resolution of calixarene negative resist in electron beam lithography
TL;DR: In this article, the calixarene derivatives were tested as high-resolution negative resists for use in electron beam lithography and the sensitivity of these resistors ranged from 700 to 7000 μC/cm2, and the required dose for dot fabrication was about 105 electrons/dot.
Journal ArticleDOI
Calixarene Electron Beam Resist for Nano-Lithography
Jun-ichi Fujita,Y. Ohnishi,Shoko Manako,Yukinori Ochiai,Eiichi Nomura,Toshitsugu Sakamoto,Shiniji Matsui +6 more
TL;DR: In this article, the resolution limit of calixarene resists is dominated by a development process such as adhesion to a substrate rather than by the electron beam profile, which is the case for most of the resistors.
Journal ArticleDOI
Calixarenes—prospective materials for nanofabrications
TL;DR: In this paper, a new group of electron resists, calixarene resists, are presented, which provide convenient means for making nanostructures, and they are described with examples of nanofabrications.
Journal ArticleDOI
Resolution of calixarene resist under low energy electron irradiation
TL;DR: In this article, the resolution and sensitivity of calixarene resists in relation to incident electron energy were studied and it was shown that the major factor in limiting the resolution in calixarella resists was not the electron beam profile, but other factors such as a limit due to development processes.
