SiC yokutidwa Isostatic Graphite Crucible

SiC Coated Isostatic Graphite Crucible yoperekedwa ndi Semixlab idapangidwa kuchokera ku premium isostatic graphite, yomwe imadziwika ndi kachulukidwe yunifolomu, kapangidwe kake kambewu kabwino, komanso mphamvu zamakina zapadera pazovuta kwambiri. Chophimba choyera kwambiri cha Chemical Vapor Deposition (CVD) silicon carbide (SiC) chimayikidwa pamwamba pa graphite, ndikupanga wosanjikiza komanso woteteza womwe umathandizira kwambiri kukana kwa okosijeni, kukhazikika kwamafuta, komanso kusakhazikika kwamankhwala. Kuphatikizika kwazinthu zapamwambazi kumatsimikizira kutenthetsa kwapamwamba, kuchepetsedwa kuipitsidwa, moyo wotalikirapo wautumiki, ndi magwiridwe antchito osasinthika pansi pazigawo zopangira ma semiconductor apamwamba kwambiri.

Kapangidwe ndi Katundu

Crucible yathu imapangidwa kuchokera kuzinthu ziwiri zofunika:

·Isostatic Graphite Substrate: Zomwe zili m'munsizi zimapangidwa kudzera mu njira yopondereza ya isostatic, yomwe imatsimikizira mawonekedwe ofanana, osasunthika kwambiri okhala ndi mphamvu zapadera zamakina komanso kukhazikika kwamafuta. Mkhalidwe wa isotropic uwu umatanthawuza kuti katundu wake ndi wofanana mbali zonse, kuteteza kumenyana ndi kusweka ngakhale pansi pa njinga yamoto yotentha kwambiri. Ma graphite oyeretsedwa kwambiri omwe timagwiritsa ntchito amachepetsa zonyansa, zomwe ndizofunikira kuti tipewe kuipitsidwa kwazinthu zodziwika bwino za semiconductor.

Kupaka Silicon Carbide(SiC): Kugwiritsidwa ntchito pogwiritsa ntchito njira yapamwamba ya Chemical Vapor Deposition (CVD), wosanjikiza wa SiC umapanga chotchinga chotchinga, chopanda porous.

Ntchito Yogwira Ntchito mu Semiconductor Processes

1. Kukula kwa SiC Crystal (Njira ya PVT)

Munjira ya Physical Vapor Transport (PVT) ya kukula kwa makristalo a SiC, crucible imagwira ntchito yofunika kwambiri pakukwaniritsa kupanga kwapamwamba kwambiri. SiC- TACHIMATA pamwamba amapereka mankhwala khola muli malo amene amalepheretsa zochita zapathengo pakati graphite gawo lapansi ndi yaiwisi SiC gwero zakuthupi. Izi zimachepetsa kuipitsidwa kwa kaboni ndikuwonjezera kufanana kwa crystal lattice. Kutentha kwapamwamba kwa crucible kumapangitsa kuti kutentha kuzikhala kokhazikika, komwe kumakhala kofunikira pakuwongolera kutentha komanso kuchepetsa kusasunthika kwamabotolo a SiC. Zotsatira zake, crucible mwachindunji imathandizira kuti pakhale zokolola za kristalo komanso mawonekedwe opindika pamakina opangira zida za semiconductor.

2. Silicon Single Crystal Kukula

Panthawi ya kukula kwa silicon single crystal (monga njira ya Czochralski), crucible iyenera kupirira kutentha kwanthawi yayitali ndikusunga kusakhazikika kwamankhwala. Kupaka kwa SiC kumagwira ntchito ngati chotchinga choteteza ku okosijeni ndi kufalikira kwa zonyansa, kuwonetsetsa kuti palibe kuipitsidwa kumasunthira mu silicon yosungunuka. Izi zimabweretsa makristalo oyera kwambiri a silicon okhala ndi zolakwika zochepa zamapangidwe, zomwe ndizofunikira popanga ma IC apamwamba, zida zamagetsi, ndi ma cell a photovoltaic. Kuphatikiza apo, zokutira zimawonjezera moyo wautumiki wa crucible, kuchepetsa kuchuluka kwa m'malo ndi mtengo wonse wopanga.

3. Kutentha Kwambiri Kutentha Kwambiri Kuchiza ndi Njira Zosakanikirana

Pochiza matenthedwe, ma annealing, ndi kufalikira, zowotcha za semiconductor zimakumana ndi kutentha komwe kumakhala chiyero ndi kukhazikika. SiC-coated crucible imapereka kukana kwabwino kwambiri polimbana ndi kutsitsa ndi kutuluka, kuteteza kutulutsa tinthu komwe kumatha kusokoneza malo opindika. Kukhazikika kwake kwamatenthedwe kumatsimikizira kutentha kofanana, komwe kumathandizira kufalikira kwa dopant ndi magwiridwe antchito osasinthika. Pokhala ndi malo oyeretsera komanso kuchepetsa kuwonongeka kwa zinthu, crucible imathandizira opanga kuti akwaniritse zowonda zodalirika, zopanda chilema pakupanga kwakukulu.

Ubwino wa Semixlab

Semixlab imadziwika kuti ndi ogulitsa odalirika pophatikiza uinjiniya wolondola komanso chitsimikizo chokhazikika. SiC Coated Graphite Crucible iliyonse imayesedwa mwamphamvu ndi fakitale kuti iwonetsetse kuti zokutira, makulidwe ofanana, komanso magwiridwe antchito pansi pa njinga yamoto yotentha. Kampaniyo imapereka mayankho makonda, kulinganiza miyeso ya crucible, makulidwe a zokutira, ndi malo apamwamba kuti akwaniritse zofunikira za ndondomekoyi.

Kupitilira kupanga, Semixlab imaperekanso chithandizo chaukadaulo komanso chithandizo chantchito, kuthandiza akatswiri opanga ma semiconductor ndi magulu ogula zinthu kusankha njira yoyenera kwambiri yolumikizirana ndi momwe amagwirira ntchito. Ndi kudzipereka kwake kolimba ku khalidwe ndi makonda, Semixlab imatsimikizira kupereka kodalirika komanso kugwira ntchito kwa nthawi yaitali pakupanga semiconductor yapamwamba.
