Kodi Graphite Yokhala ndi Porous N'chiyani? Katundu, Kugwiritsa Ntchito & Ubwino wa Semiconductor

Chiyambi: Chifukwa Chake Graphite Yokhala ndi Mitsempha Imafunika Pakupanga Ma Semiconductor

Pamene kupanga ma semiconductor kukupita ku ma node apamwamba ndi ma compound semiconductor (monga SiC), zofunikira pa zinthu zakhala zovuta kwambiri. Kukhazikika kwa kutentha kwambiri, kuyera kwambiri, komanso kuwongolera bwino kayendedwe ka mpweya tsopano ndikofunikira kwambiri.

Malinga ndi International Energy Agency, zipangizo zamakono zimathandiza kwambiri pakuthandizira ukadaulo wa mphamvu ndi semiconductor wa m'badwo wotsatira, makamaka pa zamagetsi zamagetsi zomwe zimagwira ntchito bwino kwambiri.

Pakati pa zinthu zimenezi, graphite yokhala ndi mapovu yaonekera ngati njira yofunika kwambiri yopezera kukhazikika kwa njira, kufanana, komanso kukweza zokolola.

Kodi Graphite Yokhala ndi Porous N'chiyani?

Grafiti yokhala ndi mapovu ndi chinthu chopangidwa ndi kaboni chomwe chili ndi netiweki yolamulidwa ya mapovu olumikizana, zomwe zimathandiza kuti mpweya kapena madzi alowerere pamene graphite ikusunga mawonekedwe ake enieni.

Mosiyana ndi graphite yolimba, graphite yokhala ndi porous imapereka:

● Kulowa madzi: nthawi zambiri 10⁻¹² mpaka 10⁻¹⁴ m² (kutengera kapangidwe kake)

● Kupindika kwa mpweya: nthawi zambiri 10%–30% (kutengera kapangidwe kake)

Makhalidwe amenewa amawapangitsa kukhala abwino kwambiri pakufalitsa mpweya ndi kuwongolera kutentha mu njira za semiconductor.

Kapangidwe kakang'ono ka Graphite Yokhala ndi Porous

Kapangidwe ka Kaboni

Graphite yokhala ndi porous imakhala ndi zigawo za kaboni zolumikizidwa ndi sp², zomwe zimapangitsa kuti:

● Kutentha kwa mpweya: 80–150 W/m·K (mtundu wamba)

● Kukhazikika kwa kutentha: mpaka 3000°C mumlengalenga wopanda mpweya

 Kapangidwe ka Mabowo

Kugwira ntchito kwake kumadalira mawonekedwe a pore:

● Kukula kwa mabowo: nthawi zambiri 1–100 μm

● Kutseguka kwa ma porosity: kofunikira kwambiri poyendetsa mafuta

● Malo ozungulira: kumawonjezera mawonekedwe a zochita

Kapangidwe kake ka microstructure kamatsimikizira mwachindunji kufanana kwa kayendedwe ka mpweya ndi magwiridwe antchito a njira.

Ubwino Waukulu wa Graphite Yokhala ndi Porous

1. Kutha kwabwino kwa mpweya kulowa

Ma network oyendetsedwa bwino a ma pore amathandiza kugawa mpweya mofanana, zomwe zimapangitsa kuti mpweya ukhale wofanana mu njira za CVD ndi EPI.

2. Kukana Kutentha Kwambiri

Graphite yokhala ndi mabowo imasunga kukhazikika pa:

● >2000°C m'malo opanda mpweya/opanda mpweya

● Kusintha pang'ono kwa kutentha

3. Kukhazikika Kwambiri kwa Mankhwala

● kukana dzimbiri

● Yokhazikika m'malo okhala ndi halogen ndi mpweya wochitapo kanthu

4. Yopepuka komanso Yokhazikika pa Kapangidwe kake

● Kuchuluka: nthawi zambiri 1.5–1.9 g/cm³

● Chiŵerengero champhamvu cha kulemera

5. Kuyera kwa Semiconductor-Grade

● Kuchuluka kwa phulusa: <50 ppm (magiredi oyeretsedwa kwambiri)

● Chofunika kwambiri pa njira zopewera kuipitsidwa

6. Kusinthasintha kwa Porosity

Opanga akhoza kusintha zinthu izi:

● Kukula kwa mbole

● Kuchulukana

● Kutha kulowerera

Izi zimathandiza kukonza bwino njira zina, makamaka popanga zinthu zapamwamba za semiconductor.

Kugwiritsa Ntchito Semiconductor ya Porous Graphite

Kugawa kwa Gasi mu CVD ndi Epitaxy (EPI)

Graphite yokhala ndi mabowo imatsimikizira kuti mpweya woyambirira umayenda mofanana, zomwe zimapangitsa kuti makulidwe a filimuyo akhale olimba komanso kuti ipange mafuta ambiri.

Kukula kwa Makristalo a PVT (SiC)

Amagwiritsidwa ntchito mu machitidwe owongolera kutentha, kuthandizira kukula kwa makristalo kokhazikika.

Malinga ndi zofalitsa za IEEE, kufanana kwa kutentha ndikofunikira kwambiri pakukula kwa kristalo ya SiC yapamwamba kwambiri.

 Kugwira Ntchito ndi Ma Vacuum Chucks ndi Wafer

● Kusakaniza kokhazikika kwa vacuum

● Kugawa kwa kuthamanga kofanana

 Zigawo Zoyang'anira Kutentha

● Kusamutsa kutentha bwino

● Kuchepa kwa kutentha

 Machitidwe osefera ndi Kufalitsa

● Kuyeretsa mpweya

● Malo oyendetsedwa bwino ofalitsa

Graphite Yokhala ndi Porous vs Graphite Yokhuthala

Pomaliza: Graphite yokhala ndi mabowo imalola kulamulira molondola njira zomwe graphite yokhuthala singathe kuchita.

Kodi Mungasankhe Bwanji Graphite Yokhala ndi Mabowo Oyenera?

 Magawo ofunikira owunikira:

● Kukula kwa maenje (μm level) → kumakhudza kufalikira kwa mpweya

● Kutha kulowa (m²) → kumatsimikiza momwe madzi amayendera bwino

● Kuyera (ppm level) → kumakhudza chiopsezo cha kuipitsidwa

● Kuyendetsa kutentha (W/m·K) → kumakhudza kulamulira kutentha

● Kugwirizana kwa zokutira (SiC, TaC)

Kusankha bwino kungathandize mwachindunji kukolola, kufanana, komanso kukhazikika kwa njira.
