Improving the resistance of PECVD silicon nitride to dry

Feb 01, 1997 · 4. CONCLUSIONS Oxygen plasmas have been used to enhance the resistance of PECVD SiN to dry etching in Sulfr hexafluoride, SiCI4, HBr/SiC14 and CH4/H2/O2 RIE processes. The reactive ion etching of the untreated SiN in gaz sf6 is limited by the flux density of ions reaching the sample surface, whereas the RIE of the oxygen treated SiN is limited by the ion energy.Get price
