PECVD氮化硅膜氢键及硅悬挂键的研究 Title:StudyonHydrogenandSiliconDanglingBondsinPECVDSiliconNitrideFilms Abstract: Siliconnitride(SiNx)isaversatilematerialwidelyusedinvarioustechnologicalapplications,includingmicroelectronics,optoelectronics,andnanotechnology.ThepropertiesofSiNxfilmsdependontheirhydrogenandsilicondanglingbondconfigurations,whichplayacrucialroleindeterminingtheirelectrical,optical,mechanical,andchemicalcharacteristics.Thisstudyaimstoinvestigatethehydrogenandsilicondanglingbondsinplasma-enhancedchemicalvapordeposition(PECVD)siliconnitridefilmsandtheirimpactonthefilm'spropertiesandapplications. Introduction: Siliconnitride(SiNx)filmshavegainedsignificantattentionduetotheiruniqueelectrical,optical,mechanical,andchemicalproperties.ThesefilmsarecommonlydepositedusingPECVD,whichinvolvesthedecompositionofprecursorgasesinaplasma-enhancedenvironment.Duringthedepositionprocess,hydrogenandsilicondanglingbondsareformed,significantlyaffectingthefilm'sproperties. HydrogenDanglingBonds: PECVDSiNxfilmstypicallycontainhydrogenatomsbondedeithertosiliconornitrogenatoms,creatinghydrogendanglingbondsattheinterface.Thesehydrogenbondscanleadtochargetrapping,leakagecurrents,andaffecttheopticalpropertiesofthefilm.Theconcentrationanddistributionofthesehydrogenbondscanbecontrolledbyprocessparameterssuchasplasmapower,gascomposition,anddepositiontemperature.Understandingthebehaviorandimpactofhydrogendanglingbondsiscrucialinoptimizingthefilmforspecificapplications. SiliconDanglingBonds: SilicondanglingbondsarecreatedwhensiliconatomsintheSiNxfilmarenotfullybonded.Thesebondscanresultininterfacedefects,chargetrapping,andaffectthemechanicalandchemicalstabilityofthefilm.Thepresenceofsilicondanglingbondscanbereducedbytuningthedepositionparameters,suchasnitrogen-to-siliconratio,growthtemperature,andplasmapower.Furthermore,passivationtechniquescanbeemployedtosaturatethesedanglingbondswithhydrogenorothersuitableatoms,improvingthefilm'spropertiesandstability.
