Kodi Epi Pan Carrier ndi chiyani?

Makampani opanga ma semiconductor amadalira zida zapadera kuti apange zida zamagetsi zapamwamba kwambiri. Chimodzi mwazinthu zofunika kwambiri pakukula kwa epitaxial ndi chonyamulira cha epi pan. Chida ichi chimagwira ntchito yofunika kwambiri pakuyika kwa zigawo za epitaxial pa zowotcha za semiconductor, kuwonetsetsa kuti chomalizacho chifanane ndi mtundu wake.

Epi pan carrier, yomwe imadziwikanso kuti epitaxy pan carrier, ndi tray yopangidwa mwapadera yomwe imagwiritsidwa ntchito pakukula kwa epitaxial. Imagwira ndikuthandizira ma semiconductor wafers panthawi yoyika zigawo za epitaxial. Zonyamulirazi zimapangidwira kuti zipirire kutentha kwakukulu ndi malo owononga omwe amafanana ndi njira za epitaxial, zomwe zimapereka nsanja yokhazikika ya kukula kwa zigawo za kristalo imodzi.

Zipangizo ndi Zomangamanga:

Zonyamula ma Epi pan nthawi zambiri amapangidwa kuchokera ku zinthu zomwe zimatha kupirira kutentha kwambiri ndipo sizingagwirizane ndi kusintha kwamankhwala. Zida zodziwika bwino ndi izi:

•Silicon Carbide (SiC): Imadziwika chifukwa cha matenthedwe ake apamwamba komanso kukana kuvala ndi okosijeni, SiC ndi chisankho chodziwika bwino kwa onyamula ma epi pan.

• Graphite: Nthawi zambiri amagwiritsidwa ntchito chifukwa cha kutentha kwake komanso kuthekera kosunga umphumphu pa kutentha kwakukulu. Zonyamulira graphite nthawi zambiri zimakutidwa ndi SiC kuti zithandizire kulimba kwawo komanso kukana dzimbiri.

Ntchito mu Epitaxial Growth Process:

Njira yakukula kwa epitaxial imaphatikizapo kuyika kwa zinthu zopyapyala za crystalline pagawo laling'ono kapena lopindika. Izi ndizofunikira kwambiri popanga zida za semiconductor zokhala ndi mphamvu zenizeni zamagetsi. Chonyamulira cha epi poto chimathandizira chophatikizira muchipinda chochitiramo ndikuwonetsetsa kuti chizikhala chokhazikika panthawi yoyika.

Ntchito zazikulu za epi pan carrier ndi:

• Kugawidwa kwa Kutentha Kwamtundu Wofanana: Chonyamuliracho chimatsimikizira ngakhale kutentha kwapakati pa mtanda, zomwe ndizofunikira kuti mukwaniritse makulidwe ndi khalidwe la epitaxial mosasinthasintha.

• Chemical Isolation: Popereka malo okhazikika komanso opanda inert, chonyamuliracho chimalepheretsa machitidwe osayenera a mankhwala omwe angawononge khalidwe la epitaxial layer.

Ubwino WapamwambaEpi Pan Carriers:

• Kupititsa patsogolo Kachitidwe ka Chipangizo: Ma epitaxial layers omwe ali ofanana amathandizira kuti zida za semiconductor ziziyenda bwino, zomwe zimapangitsa kuti zikhale zogwira mtima komanso zodalirika.

• Kuchuluka kwa Zokolola: Pochepetsa zolakwika ndikuwonetsetsa kuti zisanjidwe zofananira zikhalepo, zonyamulira zapamwamba zimakulitsa zokolola za ma semiconductor wafers.

• Kuchepetsa Mtengo Wokonza: Zida zokhalitsa ndi uinjiniya wolondola zimachepetsa kufunika kozisintha pafupipafupi ndi kukonza, kutsitsa mtengo wonse wopanga.

Chonyamulira cha epi pan ndi gawo lofunikira kwambiri pakukula kwa epitaxial, kukhudza mwachindunji mtundu ndi kusasinthika kwa zida za semiconductor. Posankha zipangizo zoyenera ndi mapangidwe, opanga amatha kukhathamiritsa ndondomeko ya epitaxial, zomwe zimapangitsa kuti chipangizochi chiziyenda bwino komanso kuchepetsa ndalama zopangira. Pamene kufunikira kwa zipangizo zamakono zamakono kukukula, kufunika kwapamwamba kwambiriepi pan onyamulamu makampani a semiconductor akupitiriza kuwonjezeka.
