Title: Ion beam etching in chlorine

IPC: H01L21/302
Filed: 1984-05-09
Abstract: PURPOSE:To increase the selective etching rate ratio of Si to SiO2 and permit etching by which an edge of a sample is made vertical and which involves a reduced number of damages, by simultaneously applying ultraviolet rays and ion beams with low accelerating energy to Si on a sample placed in a chlorine gas atmosphere. CONSTITUTION:A sample 41 of Si and SiO2 is placed in the atmosphere of chlorine gas 43 introduced into a vacuum device through a gas inlet tube 42. The sample 41 is irradiated with ultraviolet rays 45 from an ultraviolet light source 44 through a window 46. As a result, the chlorine gas 43 is dissociated into chlorine radicals 47 and, at the same time, the electrons of the Si on the sample 41 are excited. The sample 41 in this state is irradiated with ion beams 49 from an ion source 48 with low accelerating energy. In consequence, the Si in the excited state reacts with the chlorine radicals 47 and is etched easily. On the other hand, the SiO2 on the sample 41 is not easily etched, because it does not absorb ultraviolet rays.
