Paraihe Karāhe Isostatic Teitei-parakore

He tohunga a VET Energy ki te hanga i ngā mea kounga teitei.Para Karāhe Isostatic Teitei-ParakoreHe mea hanga mō ngā tono rauemi semiconductor me ngā rauemi matatau. He mea hanga mai i te karāhe isostatic witi tino pai, ā, he mea purea mā roto i ngā tukanga purenga halogen pāmahana-tiketike, ka tukuna e ā mātou ipu karāhe te pumau wera tino pai, ngā taumata poke iti, me te ōritetanga āhua tino pai i raro i ngā āhuatanga mahi tino kino.

He whānuitia te whakamahinga i roto i te tipu tioata SiC, te hanga tioata GaN, te hanga rauemi epitaxial, me te sintering uku matatau, Teitei-MaPara Karāpiti IsostaticHe mea nui te mahi a ēnei ki te whakarite i te kounga tioata, te pumau o ngā tukanga, me te whai huatanga o te whakaputa puta noa i te hangahanga haurua-ā-ira hou.

He aha te Para Whakarewa Karāhe Isostatic Parakore-Teitei?

He ipu tino tika te ipu paraihe Isostatic High-Purity i hangaia mai i ngā rauemi karāhe isotropic i hangaia mā te tukanga pēhi isostatic. Ki te whakatauritea ki ngā hua karāhe whakarewa tikanga, ko ngā mea e tukuna ana e te karāhe isostatic:

● Hanganga moroiti ōrite ki ngā taha katoa

● Te mātotoru teitei me te kaha ā-ringa

● Te kawe wera tino pai

● He tino ātete ki ngā ru wera

● He iti te pūngao

● He iti rawa te ihirangi poke

I muri i te purenga, ka taea te whakahaere i te nui o te pungarehu i raro i te 5 ppm, ā, ko ētahi rauemi kounga-haurua ka eke ki ngā taumata poke i raro i te 3 ppm.

Nā ēnei āhuatanga ka tino pai ngā Para Whakarewa Karāhe Isostatic Teitei-Parakore mō ngā tukanga pāmahana teitei neke atu i te 2,000°C, ina koa he mea nui te whakahaere poke me te ōritetanga o te wera.

Ngā Tūranga i roto i te Hanganga Ārahi-Hau

I roto i te tipu tioata Silicon Carbide (SiC) mā te whakamahi i te tukanga Physical Vapor Transport (PVT), ka mahi ngā ipu karāpiti hei ipu pupuri rauemi pūtake me te wāhanga nui o te pūnaha papa wera. Mā te mahi i ngā pāmahana neke atu i te 2,200°C, me pupuri tonu e te ipu te pumau o ngā āhuatanga me te tautoko i ngā pikinga pāmahana tika e hiahiatia ana mō te kawe kohu me te hanganga tioata. Ka pā tika te parakore me te hanganga isotropic o te karāpiti ki te whakaurunga poke, te tohatoha wera, te tere tipu tioata, me te whakaputa hapa.

Ko te mahi a ngā Paraihe Karāhe Ma-Teitei e horapa atu ana i tua atu i te hanga SiC ki roto i ngā hangarau tipu tioata Gallium Nitride (GaN) matatau. Ahakoa e whakamahia ana i roto i te HVPE, te tipu rere, ngā tikanga whakaputa tioata papatipu hou rānei, ka whakaratohia e ngā paraihe karāhe he taiao pāmahana teitei pumau e tautoko ana i te kawe rauemi me te hanganga tioata me te whakaiti i ngā tūponotanga poke.

I roto i te hanga rauemi epitaxial semiconductor, tae atu ki te epitaxy SiC, te tipu tioata AlN, me te tukatuka semiconductor matū matatau, ka whai wāhi ngā ipu karapiti ki te ōritetanga wera me te auau o te tukanga. Nā te pai o te kawe wera me te ātete ki te ru wera ka taea te mahi pumau i raro i ngā āhuatanga tukanga tino kino, e tautoko ana i te whakahaere tika o ngā tikanga mimiti, whakangawari, me te whakatakotoranga.

He mea nui anō hoki ngā Paraihe Karāhe Ma-Teitei mō te Hanga i ngā rauemi uku matatau me ngā paura haurua-whakatupuranga tuatoru. I te wā e whakatōngia ana te karāhe silicon carbide, te konumohe nitride, te boron nitride, me ētahi atu uku mahi-teitei, ka whakaratohia e te paraihe he taiao pumau matū me te rite o te wera e whakatairanga ana i te whakakīkī me te whakaiti i te poke. Ko ngā whakapainga hua o te ma o ngā rauemi, te kawe wera, me te mahi miihini he mea nui mō ngā tono mai i ngā wāhanga taputapu haurua-whakatupuranga ki te takai hiko mana-teitei.

Ngā Auahatanga Ahumahi me te Whanaketanga ā-Mārama

I te mea kei te haere tonu te whakarerekētanga o te umanga hikohiko mana e ngā haurua-āputa whānui-rohe, kei te tere piki haere te hiahia mō ngā ipu whakarewa karāpeti matatau.

Ngā Whakaritenga Parakore Tino-Teitei

Ko ngā tono haurua-ā-rangi a meake nei me whai taumata poke i raro i te 5 ppm, ā, i ētahi wā, me tata ki te 1 ppm hei tautoko i ngā rahi tioata nui ake me ngā kiato hapa iti iho.

Ngā Hangarau Paninga

Kei te piki haere te whakamahinga o ngā paninga mata matatau ki ngā oko whakarewa karāhe, tae atu ki:

● Paninga Silicon Carbide (SiC)

● Paninga Tantalum Carbide (TaC)

● Paninga Waro Pirolitiki (PyC)

Ka whakarei ake ēnei paninga:

● Ātete ki te waikura

● Te pumau o te wera

● Mahi mō te wā katoa

● Te horoi o te tukanga

● Ngā Hoahoa Para Nui

Te hokohoko o:

● Ngā papa SiC 8-inihi

● Ngā papa GaN nui ake

● Ngā rauemi haurua hiko matatau

kei te akiaki i te whanaketanga o ngā oko karāpeti nui ake, pumau ake te āhua, ka taea te pupuri i te mana whakahaere wera tika mō ngā huringa whakaputa roa.
