제목 Investigation on High Density Plasma Reactive Ion Etching of CoFeB Thin Films For Nonvolatile Magnetic Random Access Memory
초록 The etching of MTJ stack which is composed of magnetic materials such as CoFeB is one of the vital processes for the realization of high-density MRAM. In this study, CoFeB magnetic films were investigated in a high-density plasma using CH4/Ar and CH4/O2/Ar gas mixes. The effects of gas concentration and etch parameters such as coil rf power, dc-bias voltage to substrate and gas pressure on etch characteristics will be systematically explored.
