Research Abstract

A difference in the EB-resist pattern formation depending on the HMDS coating process was confirmed. By improvement of this process, formation of MTJ of less than 30 nm was enabled. Material research such as CoFeB/MgO stack and double MgO stack structures have been performed for realization of MTJ of less than 30 nm.
