Publication number: 20210398774Abstract: An etching device and method of inductively coupled plasma. The etching device of inductively coupled plasma includes an etching chamber, an excitation radio-frequency power supply, and a first bias radio-frequency power supply, and further includes a second bias radio-frequency power supply. The frequency of the second bias radio-frequency power supply is significantly lower than that of the first bias radio-frequency power supply. The etching rate and angle are controllable by means of the process of controlling distribution of ion energy by adjusting the radio-frequency bias of different frequencies, so as to adjust etching. In addition, since the mean free path of ions is larger, and the power utilization rate of etching is higher at the low pressure and low bias radio-frequency frequencies, rapid etching is achieved at relatively low power to implement green and energy-saving processing. The disclosure is applicable to the etching of magnetic tunnel junctions.Type: ApplicationFiled: August 21, 2019Publication date: December 23, 2021Inventors: Xiaobo LIU, Xuedong LI, Dongdong HU, Dongchen CHE, Jia WANG, Lu CHEN, Kangning XU, Kaidong XU
