High-kuchena Isostatic Graphite Crucible

VET Energy inyanzvi mukugadzira zvinhu zvemhando yepamusoroHigh-Chakachena Isostatic Graphite CrucibleYakagadzirirwa kushandiswa kwezvinhu zve semiconductor uye zvemhando yepamusoro. Yakagadzirwa kubva ku ultra-fine grain isostatic graphite uye yakacheneswa kuburikidza ne high-temperature halogen cleansing processes, graphite crucibles dzedu dzinopa kugadzikana kwakanyanya kwekupisa, mwero wakaderera wekusvibiswa, uye kugadzikana kwakanaka mumamiriro ekushanda akaipisisa.

Inoshandiswa zvakanyanya mukukura kwekristaro yeSiC, kugadzirwa kwekristaro yeGaN, kugadzirwa kwezvinhu zve epitaxial, uye kugadzirwa kwepamusoro kweceramic sintering, High-PurityIsostatic Graphite Crucibles inoita basa rakakosha mukuona kuti kristaro yakanaka, kugadzikana kwemaitiro, uye kushanda zvakanaka kwekugadzira mukati mekugadzirwa kwema semiconductor emazuva ano.

Chii chinonzi High-Purity Isostatic Graphite Crucible?

Chirongo cheGraphite Chinopenya Zvakanyanya Kuchena (High-Purity Isostatic Graphite Crucible) mudziyo wakagadzirwa nemazvo wakagadzirwa nezvinhu zvegraphite zvinogadzirwa kuburikidza nemaitiro ekudzvanya eisostatic. Kana tichienzanisa nezvigadzirwa zvegraphite zvakaumbwa, graphite inopenya inopa zvinotevera:

● Hurongwa hudiki hwakafanana munzira dzose

● Kuwanda kwakanyanya uye simba remakanika

● Kufambisa kwekupisa kwepamusoro-soro

● Kudzivirira kupisa kwakanyanya

● Kuderera kwehuremu

● Kusvibiswa kwakaderera zvakanyanya

Mushure mekucheneswa, huwandu hwedota hunogona kudzorwa pasi pe5 ppm, zvimwe zvinhu zvemhando ye semiconductor zvichisvika padanho rekusvibiswa pasi pe3 ppm.

Hunhu uhwu hunoita kuti High-Purity Isostatic Graphite Crucibles ive yakakodzera kune tembiricha yepamusoro inodarika 2,000°C, uko kudzora kusvibiswa uye kufanana kwekupisa kwakakosha.

Mabasa muKugadzira Semiconductor

Mukukura kwekristalo yeSilicon Carbide (SiC) uchishandisa maitiro ePhysical Vapor Transport (PVT), ma graphite crucibles anoshanda semudziyo unodzivirira zvinhu zvinobva uye chikamu chakakosha chesystem ye thermal field. Ichishanda patembiricha inowanzo pfuura 2,200°C, crucible inofanira kuchengetedza kugadzikana kwehukuru uku ichitsigira tembiricha chaiyo inodiwa pakufambisa utsi uye kugadzirwa kwekristalo. Kuchena uye chimiro che isotropic chegraphite zvinokanganisa zvakananga kuiswa kwetsvina, kupararira kwekupisa, mwero wekukura kwekristalo, uye kugadzirwa kwezvikanganiso.

Basa reHigh-Purity Isostatic Graphite Crucibles rinoenderera mberi kupfuura kugadzirwa kweSiC kusvika pahunyanzvi hwepamusoro hweGallium Nitride (GaN) crystal growth. Ingave yakashandiswa muHVPE, flux growth, kana nzira dziri kubuda dzekugadzira makristaro akawanda, magirafu egraphite anopa nzvimbo yakagadzikana yekupisa kwepamusoro inotsigira kutakurwa kwezvinhu uye kugadzirwa kwekristaro uku ichideredza njodzi dzekusvibiswa.

Mukugadzirwa kwezvinhu zve epitaxial zve semiconductor, kusanganisira SiC epitaxy, AlN crystal growth, uye advanced compound semiconductor processing, graphite crucibles dzinobatsira mukuita kuti kupisa kuve kwakafanana uye kudzokorora maitiro. Kufambisa kwavo kwakanaka kwekupisa uye kuramba kupisa kunogonesa kushanda kwakasimba mumamiriro ezvinhu akaomarara, zvichitsigira kudzora kwakaringana kwekubuda kwemvura, sublimation, uye nzira dzekuisa zvinhu.

Zvidimbu zveGraphite Zvakachena Zvisina Kuchena Zvine Basa Rakakosha Mukugadzirwa Kwezvinhu Zvepamusoro zveCeramic uye Upfu hweSemiconductor hwechizvarwa chechitatu. Munguva yekupisa silicon carbide, aluminium nitride, boron nitride, nezvimwe zvidimbu zveCeramic zvine Basa Rakanaka, chidimbu chinopa nzvimbo yakagadzikana uye yakafanana mukupisa iyo inokurudzira density uku ichideredza kusvibiswa. Kuvandudzika kunobva mukuchena kwezvinhu, thermal conductivity, uye mashandiro emakanika zvakakosha pakushandiswa kubva kuzvikamu zvemidziyo yesemiconductor kusvika pakurongedza kwemagetsi ane simba guru.

Maitiro Eindasitiri uye Kubudirira Kwemangwana

Sezvo ma semiconductors ane bandwidth yakakura achiramba achichinja indasitiri yemagetsi emagetsi, kudiwa kwezvigadziko zve graphite zvepamusoro kuri kuwedzera nekukurumidza.

Zvinodiwa zveKuchena Kwakanyanya

Kushandiswa kwe semiconductor mune ramangwana kunoda mwero wekusvibiswa uri pasi pe5 ppm uye, mune dzimwe nguva, kusvika pa1 ppm kutsigira saizi huru dzekristaro uye huwandu hwakaderera hwekukanganisa.

Matekinoroji Ekugadzira

Kupfeka kwepamusoro-soro kuri kushandiswa zvakanyanya pazvigadziko zve graphite, zvinosanganisira:

● Kupfeka kweSilicon Carbide (SiC)

● Kupfeka kweTantalum Carbide (TaC)

● Kupfeka kwePyrolytic Carbon (PyC)

Mapfekero aya anowedzera:

● Kudzivirira ngura

● Kugadzikana kwekupisa

● Kushanda kwehupenyu hwese

● Kuchena kwemaitiro

● Magadzirirwo Makuru eChipfukuto

Kutengeswa kwe:

● mawafer eSiC ane masendimita masere

● Zvigadziko zvikuru zveGaN

● Zvinhu zvemagetsi zvemhando yepamusoro

iri kutungamira kugadzirwa kwezvigadziko zvegrafiti zvakakura, zvakagadzikana zvakanyanya zvinokwanisa kuchengetedza kudzora kupisa kwakanyatsojeka pakufamba kwenguva refu kwekugadzira.
