Atomic layer etching of BeO using BCl3/Ar for the interface passivation layer of IIIV MOS devices
Atomic layer etching of BeO as the interface passivation layer (IPL) has been studied. Precise etch depth control of BeO was achieved with the minimal GaAs substrate recess. Therefore, it results in self-limited one monolayer etch rate=about 0.75 (/cycle).
