Tlhaloso
SiC crystal growth material ke lisebelisoa tsa morao-rao tse tsoetseng pele tse entsoeng ke Semixlab. Karolo e ka sehloohong ke block ea CVD SiC. Boleng ba SiC single crystal e hōlileng ka thepa ena e tala e ntle haholo ebile e na le boemo bo ka sehloohong indastering.
Sehlahisoa sa mantlha se khanyang
Ts'ebetso ea boitokisetso ea ho khelosa
Ho sebelisa theknoloji e ikemetseng ea patent fluidbed CVD (patent No. : ZL2024XXXXXXX), methyl trichlorosilane (MTS) joalo ka selelekela, ho fihlela:
Bohloeki > 99.9995% (GDMS kakaretso ea motheo ea tlhahlobo)
Likahare tsa naetrojene ≤0.09ppm (ha ho na tlhoekiso e eketsehileng)
Karolo ea boholo ba 4-10mm (mokhoa oa khale oa ho ikatisa <2.5mm)
Monyetla oa kholo ea kristale
| Index | mokhoa o tloaelehileng oa ho ikatisa SiC phofo | Semixlab SiC kristale ea kholo ea thepa e tala |
| Boima ba li-microtubules bo fapane | 103~ 104cm-2 | <300 cm-2 |
| Sekhahla sa tšebeliso ea lisebelisoa tse tala | 30% -40% | > 50% |
Tšireletso ea tikoloho le moruo
Ho tsoa ha tšilafalo ea Zero: hydrochloric acid e ka fokotsoa hore e be letsoai
Phokotso ea litšenyehelo ka 30%: thepa e tala methyltrichlorosilane ke k'hemik'hale e ka sehloohong ea China.
Li-crystals tsa SiC tse hōlileng ka ho sebelisa SiC kristale kgolo lisebelisoa tse tala
Boitsebiso bo potlakileng:
1. Mabitso a mang: CVD SiC block; Sekhechana sa SiC.
2. Kopo: Lintho tse tala bakeng sa kholo ea kristale e le 'ngoe ea SiC.
3. Mekhahlelo ea mantlha: Bohloeki> 99.9995% (GDMS kakaretso ea tlhahlobo ea motheo), Likahare tsa naetrojene ≤0.09ppm (ha ho na tlhoekiso e eketsehileng), boholo ba likaroloana 4-10mm (mokhoa oa ho itlosa bolutu oa setso <2.5mm).

dikopo
Lisebelisoa tse tala bakeng sa kholo ea kristale e le 'ngoe ea SiC.
Molemo oa Khatello
1. Katleho ea bohloeki
Bohloeki ≥99.9995% (GDMS kakaretso ea lintlha). Likahare tsa naetrojene ≤0.09ppm li fihletsoe ka ho beha mouoane oa lik'hemik'hale (ha ho na tlhoekiso ea bobeli). Haholo-holo a loketse bakeng sa semi-insulating SiC single kristale litlhoko tsa kgolo.
2. Boholo ba likaroloana le ho ntlafatsa boima ba 'mele
Boholo bo boholo ba likaroloana (4-10mm), bo ntlafatsa haholo matla a crucpot loading (ho feta 1.5kg bakeng sa molumo o tšoanang), fokotsa mefokolo ea carbon encapsulation nakong ea kholo ea kristale.
3. Molemo oa litšenyehelo o bohlokoa
Fokotsa litšenyehelo tsa thepa e tala ka 30%.
Ho sebelisa methyltrichlorosilane (MTS) joalo ka selelekela, theko ea thepa e tala ke 1/3 feela ea sekeme sa setso sa silika se phahameng se hloekileng + sa graphite. Sekhahla sa tšebeliso ea thepa e tala> 50% (mokhoa oa setso feela 30% -40%).
4. Ts'ireletso ea tikoloho e koetsoe ka mokhoa oa loop
Khaso ea tšilafalo e se nang letho.
Hydrochloric acid, sehlahisoa sa tlhahiso, se hlahisa letsoai le se nang kotsi ka karabelo ea ho se nke lehlakore, ho qoba ka ho feletseng mathata a mararo a phekolo ea litšila ea mekhoa ea setso (litšenyehelo tsa ho hloekisa / ho senya khase li ikarabella ho feta 15%).
5. Ho tlola boleng ba kristale
Boima ba li-microtubules bo ne bo le ka tlase ho 300 cm-2.
Karolelano ea athomo ea Si / C ea lihlahisoa tse tala e haufi le 1: 1 (ho kheloha mokhoa oa setso> 5%), ho fokotsa mefokolo ea ho arohana ha silicon nakong ea kholo ea kristale. Lihlahisoa tsa Ingot tsa 85% -92% (65% -75% ea lihlahisoa tse hlōlisanang), ho fokotsa tahlehelo e le 'ngoe ea kristale ea ho itšeha ea bareki ba tlaase.
