Ndi chitukuko chofulumira cha 5G, intelligence intelligence (AI) ndi Internet of Things (IoT), kufunikira kwa zipangizo zogwira ntchito kwambiri pamakampani a semiconductor kwawonjezeka kwambiri.Zirconium tetrachloride (ZrCl₄), monga chinthu chofunika kwambiri cha semiconductor, chakhala chofunikira kwambiri pazitsulo zamakono (monga 3nm / 2nm) chifukwa cha ntchito yake yofunika kwambiri pokonzekera mafilimu apamwamba.
Zirconium tetrachloride ndi mafilimu apamwamba-k
Pakupanga semiconductor, mafilimu apamwamba-k ndi chimodzi mwazinthu zofunika kwambiri pakuwongolera magwiridwe antchito a chip. Pamene njira ya kuchepa kosalekeza kwa zida zachikhalidwe za silicon-based gate dielectric zida (monga SiO₂), makulidwe awo amayandikira malire, zomwe zimapangitsa kuti kuchuluke kuchuluke komanso kuwonjezeka kwakukulu kwakugwiritsa ntchito mphamvu. Zida zapamwamba (monga zirconium oxide, hafnium oxide, etc.) zimatha kuwonjezera kukula kwa thupi la dielectric wosanjikiza, kuchepetsa mphamvu ya tunneling, motero kumapangitsa kukhazikika ndi ntchito ya zipangizo zamagetsi.
Zirconium tetrachloride ndizofunikira kwambiri pokonzekera mafilimu apamwamba kwambiri. Zirconium tetrachloride imatha kusinthidwa kukhala mafilimu oyeretsedwa kwambiri a zirconium oxide kudzera munjira monga chemical vapor deposition (CVD) kapena atomic layer deposition (ALD). Makanemawa ali ndi zida zabwino kwambiri za dielectric ndipo amatha kupititsa patsogolo magwiridwe antchito komanso mphamvu zama tchipisi. Mwachitsanzo, TSMC inayambitsa zipangizo zatsopano zosiyanasiyana ndi kusintha kwa ndondomeko mu ndondomeko yake ya 2nm, kuphatikizapo kugwiritsa ntchito mafilimu apamwamba a dielectric nthawi zonse, omwe adapeza kuwonjezeka kwa transistor kachulukidwe ndi kuchepetsa kugwiritsa ntchito mphamvu.
Global Supply Chain Dynamics
Mu Global semiconductor supply chain, kaperekedwe ndi kamangidwe kazirconium tetrachloridendi zofunika kwambiri pa chitukuko cha makampani. Pakalipano, mayiko ndi zigawo monga China, United States ndi Japan ali ndi udindo wofunikira pakupanga zirconium tetrachloride komanso zokhudzana ndi zipangizo zamakono zowonongeka.
Kupita patsogolo kwaukadaulo ndi chiyembekezo chamtsogolo
Kupambana kwaukadaulo ndizinthu zazikulu zolimbikitsira kugwiritsa ntchito zirconium tetrachloride mumakampani a semiconductor. M'zaka zaposachedwa, njira ya optimization of atomic layer deposition (ALD) yakhala malo opangira kafukufuku. Njira ya ALD imatha kuwongolera molondola makulidwe ndi kufanana kwa filimuyo pa nanoscale, potero kumapangitsa mafilimu apamwamba kwambiri a dielectric. Mwachitsanzo, gulu lofufuza la Liu Lei la ku yunivesite ya Peking linakonza filimu ya dielectric yosalekeza ya amorphous pogwiritsa ntchito njira yonyowa ya mankhwala ndikuyigwiritsa ntchito bwino pazida ziwiri za semiconductor zamagetsi.
Kuphatikiza apo, pamene njira za semiconductor zikupitilira kukula mpaka kukula kochepa, kuchuluka kwa zirconium tetrachloride kukukulirakulira. Mwachitsanzo, TSMC ikukonzekera kukwanitsa kupanga ukadaulo wa 2nm mu theka lachiwiri la 2025, ndipo Samsung ikulimbikitsanso kwambiri kafukufuku ndi chitukuko cha njira yake ya 2nm. Kukwaniritsidwa kwa njira zapamwambazi sikungasiyanitsidwe ndi chithandizo cha mafilimu opangidwa ndi dielectric nthawi zonse, ndipo zirconium tetrachloride, monga chinthu chofunika kwambiri, ndizofunika kudziwonetsera.
Mwachidule, gawo lalikulu la zirconium tetrachloride mumakampani a semiconductor likukula kwambiri. Ndi kutchuka kwa 5G, AI ndi intaneti ya Zinthu, kufunikira kwa tchipisi tochita bwino kwambiri kukukulirakulira. Zirconium tetrachloride, monga kalambulabwalo wofunikira wa makanema apamwamba a dielectric nthawi zonse, itenga gawo losasinthika polimbikitsa chitukuko chaukadaulo wa chip wa m'badwo wotsatira. M'tsogolomu, ndi kupita patsogolo kosalekeza kwaukadaulo komanso kukhathamiritsa kwapadziko lonse lapansi, chiyembekezo chogwiritsa ntchito zirconium tetrachloride chidzakhala chokulirapo.
