I-Silicon Thermal Oxide Wafer

Incazelo emfushane:

I-WeiTai Energy Technology Co., Ltd. ingumphakeli ohamba phambili ogxile ekusetshenzisweni kwe-wafer kanye ne-semiconductor ethuthukisiwe.Sizinikezele ekuhlinzekeni ngemikhiqizo yekhwalithi ephezulu, ethembekile, kanye nentsha ekukhiqizeni ama-semiconductor, imboni ye-photovoltaic nezinye izinkambu ezihlobene.

Umugqa wethu womkhiqizo uhlanganisa imikhiqizo ye-graphite ehlanganiswe ne-SiC/TaC nemikhiqizo yobumba, ehlanganisa izinto ezihlukahlukene ezifana ne-silicon carbide, i-silicon nitride, ne-aluminium oxide nokunye.

Njengamanje, siwukuphela komkhiqizi ohlinzeka ngokuhlanzeka kwe-SiC 99.9999% kanye ne-99.9% ye-silicon carbide eyenziwe kabusha.Ubude bokunamathela be-SiC obukhulu singenza ama-2640mm.

Imininingwane Yomkhiqizo

Omaka bomkhiqizo

Ungqimba lwe-thermal oxide lwe-silicon wafer ungqimba lwe-oxide noma ungqimba lwe-silica olwakhiwe endaweni engenalutho ye-silicon wafer ngaphansi kwezimo zokushisa eziphezulu ezine-oxidizing agent.Ungqimba lwe-thermal oxide lwe-silicon wafer luvamise ukukhuliswa esithandweni somlilo esivundlile, futhi izinga lokushisa lokukhula livamise ukuba ngu-900 ° C ~1200 ° C, futhi kunezindlela ezimbili zokukhula "ze-oxidation emanzi" kanye "ne-oxidation eyomile".Isendlalelo se-thermal oxide yisendlalelo se-oxide "esikhulile" esine-homogeneity ephakeme namandla e-dielectric aphezulu kunesendlalelo se-oxyde efakwe i-CVD.I-thermal oxide layer iyisendlalelo esihle kakhulu se-dielectric njenge-insulator.Kumadivayisi amaningi asekelwe ku-silicon, ungqimba lwe-thermal oxide ludlala indima ebalulekile njengesendlalelo sokuvimbela i-doping kanye ne-surface dielectric.

Amathiphu: Uhlobo lwe-oxidation

1. I-oxidation eyomile

I-silicon iphendulana nomoya-mpilo, futhi ungqimba lwe-oxide luthuthela ungqimba oluyisisekelo.I-oxidation eyomile idinga ukwenziwa ekushiseni kuka-850 kuya ku-1200 ° C, futhi izinga lokukhula liphansi, elingasetshenziswa ekukhuleni kwesango lokufakwa kwe-MOS.Uma ikhwalithi ephezulu, ungqimba lwe-silicon oxide oluncane kakhulu ludingeka, i-oxidation eyomile iyakhethwa kune-oxidation emanzi.

Umthamo we-oxidation owomile: 15nm~300nm(150A ~ 3000A)

2. I-oxidation emanzi

Le ndlela isebenzisa ingxube ye-hydrogen nomoya-mpilo ohlanzekile kakhulu ukuze ishise ku-~1000 ° C, ngaleyo ndlela ikhiqize umhwamuko wamanzi ukuze kwakhe ungqimba lwe-oxide.Nakuba i-oxidation emanzi ayikwazi ukukhiqiza ungqimba lwe-oxidation olusezingeni eliphezulu njenge-oxidation eyomile, kodwa okwanele ukuze kusetshenziswe njengendawo yokuhlukanisa, uma kuqhathaniswa ne-oxidation eyomile kunenzuzo ecacile ukuthi inezinga eliphezulu lokukhula.

Umthamo we-oxidation omanzi: 50nm~ 15µm (500A ~15µm)

3. Indlela eyomile - indlela emanzi - indlela eyomile

Ngale ndlela, umoya-mpilo ohlanzekile owomile ukhishwa esithandweni se-oxidation ekuqaleni, i-hydrogen yengezwa phakathi ne-oxidation, futhi i-hydrogen igcinwa ekugcineni ukuze kuqhutshekwe ne-oxidation nge-oxygen ehlanzekile eyomile ukuze yakhe isakhiwo se-oxidation esiqinile inqubo ye-oxidation emanzi evamile ngendlela yesitimu samanzi.
