氧化剂和蚀刻剂的两种组合,H2SO4:H2O2:HF和HNO3:HF,已被用于在晶片键合之前对硅表面进行改性。通过调节混合物的HF含量,可以在0和10埃之间调节化学氧化物厚度
Two combinations of oxidizing and etching agents, H2SO4:H2O2:HF and HNO3:HF, have been used to modify silicon surfaces prior to wafer bonding. The chemical oxide thickness can be adjusted between 0 and 10 Angstrom by tuning the HF content of the mixtures
