Me pēhea te arotau i tō utu hoko mō ngā anga whakarewa silicon carbide kounga teitei

He aha te āhua utu nui o ngā angaanga Silicon Carbide—ā, he aha te korenga o taua tirohanga i oti

E kitea ana te utu nui o ngā papa waro silicon carbide (SiC) i roto i te hanga hiko haurua-hiko. Ahakoa ehara tēnei whakaaro i te mea kāore i te tino mārama, kāore anō hoki i te tino oti. Ehara i te utu tuturu o ngā papa waro SiC te wero tūturu, engari ko te kore taurite i waenga i te kounga o ngā papa waro, ngā whakaritenga taputapu, me ngā putanga hanga mō te wā roa.

I roto i te mahi, he maha ngā rautaki hoko e aro nui ana ki te utu o te waeine wafer, me te kore e aro ki te whanonga hua, te aro ki ngā hapa, te pumau o te tuku, me te utu o te huringa ora. Ka tīmata te arotautanga utu whai hua mā te huri i te hoko wafer SiC hei whakatau hangarau me te whakahaere, ehara i te mea he tauwhitinga hoko noa iho.

1. Neke atu i te Utu Wāhanga: Arotahi ki te Utu Hua Whai Hua

Kāore te Utu Ingoa e Whakaatu i te Utu Hanga Tuturu

Kāore te utu iti o te wafer e tohu ana i te utu iti o te taputapu. I roto i te hanga SiC, ko te hua hiko, te ōritetanga taurite, me ngā reiti para e peia ana e te hapa te mea nui rawa atu i te hanganga utu whānui.

Hei tauira, ko ngā wafer he nui ake te matotoru o ngā paipa iti, he ātete pumau rānei, tera pea he iti te utu i te hoko engari ka arahi ki:

• He iti ake te hua o te mate mō ia papa

• Te pikinga o ngā utu mahere me te tirotiro wafer

• Te rerekētanga o te tukanga whakararo teitei ake

Tirohanga Utu Whai Hua

Ngā tirohanga matua:

Ko te wafer tino ohanga ko te mea e whakaputa ana i te maha rawa o ngā taputapu pono, ehara i te mea he iti rawa te uara nama.

2. Te Whakatakotoranga Nui: He Pūtake Huna o te Pikinga Utu

Kāore e hiahiatia ana ngā Wafer "Top-Tier" mō ngā tono katoa

He maha ngā kamupene e whakamahi ana i ngā whakaritenga wafer tino ātaahua rawa atu—he maha ngā wā ka whakatauritea ki ngā paerewa IDM motuka, ki ngā paerewa matua rānei—me te kore e arotake anō i ngā whakaritenga tono tuturu.

Ka puta te whakatakotoranga nui rawa i roto i:

• Ngā taputapu ahumahi 650V me ngā whakaritenga roa-ora

• Kei te haere tonu ngā mahi hoahoa hou mō ngā papaaho hua o te wāhanga tuatahi

• Ngā tono kei reira kē te taupatupatu, te tango rānei i te taupatupatu

Whakatakotoranga vs. Taurite Taupānga

Te panoni rautaki:

Me arotahi te hokohoko kingā whakatakotoranga e rite ana ki te tono, ehara i te mea ko ngā anga "tino pai rawa atu e wātea ana".

3. Ka hinga te mōhiotanga ki ngā hapa i te whakakorenga o ngā hapa

Kāore i te rite te hiranga o ngā hapa katoa

I roto i ngā anga SiC, he rerekē ngā hapa i roto i te pānga hiko, te tohatoha ā-wāhi, me te aro o te tukanga. Mēnā ka whakaarohia ngā hapa katoa he mea kāore e whakaaetia, ka piki ake te utu kāore e tika ana.

Te Arotautanga Utu Whaihua

Engari i te tono "kore hapa," ko ngā kaihoko matatau:

• Tautuhia ngā matapihi manawanui hapa motuhake mō te taputapu

• Honoa ngā mahere hapa ki ngā raraunga rahunga mate tuturu

• Tukua kia ngāwari ngā kaiwhakarato i roto i ngā rohe kāore i te tino hira

Mā tēnei huarahi mahi tahi ka hua ake he ngāwari nui ki te whakatau i ngā utu, me te kore e whakararu i te mahi mutunga.

4. Wehewehea te Kounga o te Papa i te Mahi Epitaxial

Ka Mahi ngā Pūrere i runga i te Epitaxy, Kaua i runga i ngā Papa Tahanga

Ko tētahi whakaaro hē noa i roto i te hoko SiC ko te whakataurite i te tino pai o te papa ki te mahi a te taputapu. Ko te mea pono, kei roto i te paparanga epitaxial te rohe taputapu hohe, ehara i te papa tonu.

Mā te whakataurite atamai i te taumata o te papa me te utu epitaxial, ka taea e ngā kaihanga te whakaiti i te utu katoa me te pupuri tonu i te pono o te taputapu.

Whakataurite Hanganga Utu

Ngā mea matua hei ako:

Ko te whakaiti i ngā utu rautaki kei roto i te hononga i waenga i te kōwhiringa papa me te hangarau epitaxial.

5. He Utu te Rautaki Mekameka Tuku, Ehara i te Mahi Tautoko

Āraia te Whakawhirinakitanga ki te Pūtake Kotahi

I a ia e ārahi anaNgā kaiwhakarato wafer SiCe tuku ana i te pakari hangarau me te pono, ko te whakawhirinaki motuhake ki tētahi kaihoko kotahi ka hua ake i ēnei mea:

• He iti noa te ngāwari o te utu

• Te tūponotanga ki te mōrearea tohatoha

• Te puhoi o te urupare ki ngā piki me ngā heke o te tono

Ko tētahi rautaki pakari ake ko:

• Kotahi te kaiwhakarato matua

• Kotahi, e rua rānei ngā puna tuarua whai mana

• Te pūtake wehewehea e te akomanga ngaohiko, e te whānau hua rānei

He pai ake te mahi tahi mō te wā roa i te whiriwhiringa mō te wā poto

He nui ake te tūponotanga ka tukuna e ngā kaiwhakarato he utu pai ina:

• Tohaina ngā matapae tono mō te wā roa

• Whakaratohia he tukanga me te tuku urupare

• Whakauru wawe ki te whakamāramatanga o ngā whakatakotoranga

Ka puta te painga utu mai i te mahi tahi, ehara i te pēhanga.

6. Te Whakamārama Anō i te "Utu": Te Whakahaere i te Mōrearea hei Taurangi Pūtea

Kei roto i te Utu Tuturu o te Hokonga te Mōrearea

I roto i te hanga SiC, ka pā tika ngā whakataunga hoko ki te mōrearea whakahaere:

• Te piki me te heke o te hua

• Ngā whakaroa mō te tohu mātauranga

• Te aukati i te tuku

• Ngā whakamaharatanga pono

He maha ngā wā ka iti ake te rerekētanga o te utu o te wafer i ēnei mōrearea.

Te Whakaaro Utu Whakatikatika-Mōrearea

Whāinga whakamutunga:

Whakaitihia te tapeke o ngā utu kua whakatikatikaina ki te mōrearea, kaua te whakapaunga hoko noa iho.

Whakatau: He Whakatau Hangarau te Hokonga Wafer SiC

Ko te arotau i te utu hoko mō ngā anga silicon carbide kounga teitei me huri te whakaaro—mai i te whiriwhiringa utu ki te ōhanga hangarau taumata-pūnaha.

Ko ngā rautaki tino whai hua ko:

• Ngā whakatakotoranga o te wafer me te ahupūngao o te taputapu

• Ngā taumata kounga me ngā āhuatanga o te tono

• Ngā whanaungatanga ki ngā kaiwhakarato me ngā whāinga hanga roa

I te wā o SiC, ehara te hiranga o te hokohoko i te pūkenga hoko noa iho—engari he pūkenga matua nō te hangarau haurua-ā-ira.
