SiC Doonta Nadiifinta Sare

Doonta silikoon carbide (SiC) nadiif ah oo saraysa waa side dhoobada wax qabadkeedu sareeyo oo loogu talagalay hababka heerkulku sareeyo, korriinka crystal iyo daaweynta kulaylka saxda ah. Waxaa lagu dhex daray walxo SiC oo nadiif ah oo aad u sarreeya waxayna leedahay iska caabin heerkul sare oo heer sare ah, caabbinta shoogga kulaylka iyo xasilloonida kiimikada. Waxaa si weyn loogu isticmaalaa faafinta semiconductor, CVD, epitaxy LED iyo kobaca hal crystal photovoltaic.

Codsiga:

Nadiifinta Sare ee SiC Boat waa habka semiconductor-ka muhiimka ah ee la isticmaalo, inta badan loo isticmaalo in lagu qaado laguna wareejiyo waferrada jawiyada heerkulka sareeyo, waxaana si weyn loogu isticmaalaa faafinta waferka silikoon, oksaydheynta, annealing iyo hababka CVD. Waxay si gaar ah ugu habboon tahay hababka heerkulka sare ee jiilka saddexaad ee semiconductors (sida SiC/GaN) iyo qalabka korontada.

Adeegyada la bixin karo:

Falanqaynta xaaladda codsiga macaamiisha, agabka u dhigma, xallinta dhibaatada farsamada.

Astaanta shirkadda:

Semixlab waxay leedahay 2 shaybaar, koox khubaro ah oo leh 20 sano oo waayo-aragnimo agab ah, oo leh R&D iyo awoodaha wax soo saarka, tijaabinta iyo xaqiijinta.

Halbeegyada Technical

Goobaha codsiga ee ugu muhiimsan

Taageerada xaqiijinta silsiladda deegaanka

Xaqiijinta silsiladda deegaanka ee Semixlab High-Purity SiC Boat waxay dabooshaa alaabta ceeriin ee wax soo saarka, waxay dhaaftay shahaado heer caalami ah, waxayna leedahay tiro teknooloji ah oo la ruqseeyay si loo hubiyo in la isku halleyn karo iyo sii jiritaankeeda semiconductor iyo beeraha tamarta cusub.

Habka codsiga caadiga ah

Diyaarinta Qalabka Ceyriinka ah (Budada SiC ee Nadiifinta Sare) → Habka Sameynta (Cudurka Qalalan / Cadaadiska Istatic) → Habka Qallajinta

Iyada oo loo marayo hagaajinta cabbirka habka gees-goynta, Semixlab High-Purity SiC Boat naqshadeynta qaabdhismeedkeeda gaarka ah waxay hubisaa xasilloonida wafer-ka iyada oo si weyn u yareyneysa khatarta wasakheynta walxaha. Nolosheeda adeeg waxay gaari kartaa 5-8 jeer marka loo eego doomaha quartz-dhaqameedka, taasoo ka dhigaysa xal qaadis ku habboon habaynta waferka heerkulkiisu sarreeyo. Hal-abuurkan ayaa awood u siinaya inuu si tartiib tartiib ah u beddelo soo dejinta suuqa semiconductor, isagoo siinaya wax-qabad sare, xal gudaha ah oo kharash-ool ah.

Si aad u hesho tilmaamo farsamo oo faahfaahsan, waraaqo cadcad, ama diyaarinta tijaabada muunad, fadlan la xidhiidh Kooxdayada Taageerada Farsamada si aad u sahamiso sida Semixlab u wanaajin karo hufnaanta nidaamkaaga.

Semixlab Sare-Nadiifinta Sare ee SiC Doonta faa'iidooyinka xudunta u ah

1. Nadaafad xad dhaaf ah (faa'iidada muhiimka ah)

Semixlab High-Purity SiC Boat wuxuu leeyahay nadiif aad u sarreeya (≥99.9999%), iyo nuxurka wasakhda ah (Fe, Al, Na, iwm.) waxaa lagu xakameynayaa heerka 1 ppm si looga fogaado wasakheynta wafers ama walxaha epitaxial, kaas oo si gaar ah ugu habboon wax soo saarka SiC/GaN semiconductor.

2. Kiimikada firfircoonida (iska caabinta daxalka)

U adkaysta aashitada, alkali/plasma nabaad guurka, oo iska caabin kara gaasaska daxalka ah sida HF, HCl, H2(sida hababka etching semiconductor). Wax gaas ah laguma sii dayn heerkulka sare.

3. Awoodda makaanikada iyo cimriga

Adag aadka u sarreeya, caabbinta xidhashada heer sare ah, waxay yaraynaysaa halista daadinta walxaha, waxayna kordhisaa nolosha adeegga (badanaa 3 ilaa 5 jeer marka loo eego doonta quartz). Aan si sahal ah u dhalanin heerkul sare, ilaalinaya fidsanaanta wafer (sida warwarka foornada faafinta <0.1mm).

4. Habraaca waafaqid

La qabsan kara jawiga qallafsan ee kala duwan, jawiga oksaydhka/yaraynta (sida O2, H2, Ar) iyo CVD/PVD hababka daahan Dusha sare waa la habeyn karaa, sida polishing (Ra<0.1μm) ama dahaarka (sida SiO2) si loo sii yareeyo wasakhda.
