Ka nts'etsopele e potlakileng ea 5G, bohlale ba maiketsetso (AI) le Marang-rang a Lintho (IoT), tlhoko ea lisebelisoa tse sebetsang hantle indastering ea semiconductor e eketsehile haholo.Zirconium tetrachloride (ZrCl₄), e le thepa ea bohlokoa ea semiconductor, e fetohile thepa e tala e hlokahalang bakeng sa lisebelisoa tse tsoetseng pele (tse kang 3nm / 2nm) ka lebaka la karolo ea eona ea bohlokoa ho lokiseng lifilimi tse phahameng.
Zirconium tetrachloride le lifilimi tse phahameng-k
Ka tlhahiso ea semiconductor, lifilimi tse phahameng tsa k ke e 'ngoe ea lisebelisoa tsa bohlokoa bakeng sa ho ntlafatsa ts'ebetso ea chip. Ha ts'ebetso ea ho fokotseha ho tsoelang pele ha lisebelisoa tsa dielectric tsa heke tse entsoeng ka silicon (tse kang SiO₂), botenya ba tsona bo atamela moeli oa 'mele, e leng se bakang ho lutla ho eketsehileng le keketseho e kholo ea tšebeliso ea matla. Lisebelisoa tse phahameng tsa k (tse kang zirconium oxide, hafnium oxide, joalo-joalo) li ka eketsa ka katleho botenya ba 'mele oa lera la dielectric, li fokotsa phello ea tunneling, kahoo li ntlafatsa botsitso le ts'ebetso ea lisebelisoa tsa elektronike.
Zirconium tetrachloride ke selelekela sa bohlokoa bakeng sa ho lokisoa ha lifilimi tse phahameng tsa k. Zirconium tetrachloride e ka fetoloa lifilimi tse phahameng tsa zirconium oxide ka mekhoa e kang lik'hemik'hale tsa mouoane oa lik'hemik'hale (CVD) kapa atomic layer deposition (ALD). Lifilimi tsena li na le thepa e ntle ea dielectric mme li ka ntlafatsa haholo ts'ebetso le ts'ebetso ea matla ea li-chips. Mohlala, TSMC e hlahisitse lisebelisoa tse ncha tse fapaneng le ntlafatso ea ts'ebetso ts'ebetsong ea eona ea 2nm, ho kenyelletsa le ts'ebeliso ea lifilimi tse phahameng tsa dielectric khafetsa, tse fihletseng keketseho ea letsoalo la transistor le phokotso ea tšebeliso ea matla.
Global Supply Chain Dynamics
Ka ketane ea phepelo ea semiconductor ea lefats'e, mokhoa oa phepelo le tlhahiso eazirconium tetrachlorideli bohlokoa ho nts'etsopele ea indasteri. Hajoale, linaha le libaka tse kang China, United States le Japane li na le boemo ba bohlokoa tlhahisong ea zirconium tetrachloride le lisebelisoa tse phahameng tsa kamehla tsa dielectric.
Likhatelo-pele tsa theknoloji le litebello tsa nako e tlang
Katleho ea thekenoloji ke lintlha tse ka sehloohong tsa ho khothaletsa tšebeliso ea zirconium tetrachloride indastering ea semiconductor. Lilemong tsa morao tjena, ts'ebetso ea optimization ea atomic layer deposition (ALD) e fetohile sebaka sa lipatlisiso. Mokhoa oa ALD o ka laola ka nepo botenya le ho tšoana ha filimi ho nanoscale, ka hona ho ntlafatsa boleng ba lifilimi tse phahameng tsa dielectric kamehla. Ka mohlala, sehlopha sa lipatlisiso sa Liu Lei oa Univesithi ea Peking e lokiselitse filimi e phahameng ea dielectric kamehla ea amorphous ka mokhoa oa lik'hemik'hale tse metsi 'me ba e sebelisa ka katleho ho lisebelisoa tsa elektronike tsa semiconductor tse peli.
Ntle le moo, ha lits'ebetso tsa semiconductor li ntse li tsoela pele ho fihlela boholo bo nyane, sebaka sa ts'ebeliso ea zirconium tetrachloride le sona se ntse se hola. Mohlala, TSMC e rera ho fihlela tlhahiso e kholo ea thekenoloji ea 2nm halofong ea bobeli ea 2025, mme Samsung e boetse e khothaletsa lipatlisiso le nts'etsopele ea ts'ebetso ea eona ea 2nm ka mafolofolo. Ho phethahala ha mekhoa ena e tsoetseng pele ho ke ke ha arohanngoa le tšehetso ea lifilimi tse phahameng tsa dielectric kamehla, 'me zirconium tetrachloride, e le lisebelisoa tsa bohlokoa tse tala, ke tsa bohlokoa bo iponahatsang.
Ka kakaretso, karolo ea bohlokoa ea zirconium tetrachloride indastering ea semiconductor e ntse e tsoela pele ho hlahella. Ka ho tsebahala ha 5G, AI le Marang-rang a Lintho, tlhoko ea lichifi tse sebetsang hantle e ntse e eketseha. Zirconium tetrachloride, e le selelekela sa bohlokoa sa lifilimi tse sa feleng tsa dielectric, e tla bapala karolo e ke keng ea nkeloa sebaka ho nts'etsapele nts'etsopele ea theknoloji ea chip ea moloko o latelang. Nakong e tlang, ka tsoelo-pele e tsoelang pele ea thekenoloji le ntlafatso ea ketane ea phepelo ea lefats'e, litebello tsa tšebeliso ea zirconium tetrachloride li tla ba tse pharaletseng.
