Iyini I-Epi Pan Carrier?

Imboni ye-semiconductor incike emishinini ekhethekile kakhulu ukukhiqiza imishini ye-elekthronikhi esezingeni eliphezulu. Enye ingxenye ebaluleke kangaka kunqubo yokukhula kwe-epitaxial isithwali se-epi pan. Lezi zisetshenziswa zidlala indima ebalulekile ekufakweni kwezingqimba ze-epitaxial kuma-wafers we-semiconductor, okuqinisekisa ukufana kanye nekhwalithi yomkhiqizo wokugcina.

I-epi pan carrier, eyaziwa nangokuthi i-epitaxy pan carrier, iyithreyi eklanywe ngokukhethekile esetshenziswa kunqubo yokukhula kwe-epitaxial. Ibamba futhi isekele ama-wafers we-semiconductor ngesikhathi sokubekwa kwezingqimba ze-epitaxial. Lezi zinkampani zenethiwekhi zenzelwe ukumelana namazinga okushisa aphezulu kanye nezindawo ezonakalisayo ezivamile zezinqubo ze-epitaxial, zinikeza inkundla ezinzile yokukhula kwezingqimba zekristalu eyodwa.

Izinto zokwakha nokwakha:

Izithwali ze-Epi pan ngokuvamile zenziwa ngezinto ezikwazi ukumelana namazinga okushisa aphakeme futhi zimelana nokusabela kwamakhemikhali. Izinto ezijwayelekile zifaka:

•I-Silicon Carbide (SiC): Iyaziwa ngokuba ne-thermal conductivity ephezulu kanye nokumelana nokugqoka kanye ne-oxidation, i-SiC iyisinqumo esidumile sabathwali be-epi pan.

• I-Graphite: Ivame ukusetshenziswa ngenxa yezakhiwo zayo ezishisayo ezihle kakhulu nekhono lokugcina ubuqotho besakhiwo emazingeni okushisa aphezulu. Izithwali ze-graphite zivame ukumbozwa nge-SiC ukuze zithuthukise ukuqina kwazo kanye nokumelana nokugqwala.

Iqhaza Kunqubo Yokukhula Kwe-Epitaxial:

Inqubo yokukhula kwe-epitaxial ihilela ukubekwa kongqimba oluncane lwe-crystalline material ku-substrate noma i-wafer. Le nqubo ibalulekile ekudaleni amadivaysi e-semiconductor anezici zikagesi ezinembile. Isithwali se-epi pan sisekela i-wafer egumbini lokusabela futhi siqinisekisa ukuthi sihlala sizinzile phakathi nenqubo yokubeka.

Imisebenzi ebalulekile ye-epi pan carrier ihlanganisa:

• Ukusabalalisa Ukushisa Okufanayo: Inkampani yenethiwekhi iqinisekisa ngisho nokusatshalaliswa kokushisa kuyo yonke i-wafer, okubalulekile ukuze kuzuzwe ukujiya kwe-epitaxial layer nekhwalithi engashintshi.

• I-Chemical Isolation: Ngokuhlinzeka ngendawo ezinzile nengenayo, inkampani yenethiwekhi ivimbela ukusabela kwamakhemikhali okungafuneki okungahle kwehlise ikhwalithi ye-epitaxial layer.

Izinzuzo Zekhwalithi EphezuluI-Epi Pan Carriers:

• Ukusebenza Kwedivayisi Okuthuthukisiwe: Izendlalelo ze-epitaxial ezifanayo zifaka isandla ekusebenzeni okuphakeme kwamadivayisi we-semiconductor, okuholela ekusebenzeni kangcono nokuthembeka.

• Isivuno Esikhulisiwe: Ngokunciphisa ukukhubazeka kanye nokuqinisekisa ukubekwa kongqimba olufanayo, abathwali bekhwalithi ephezulu bathuthukisa isivuno samawafa angama-semiconductor asebenzisekayo.

• Izindleko Ezincishisiwe Zokulungisa: Izinto ezihlala isikhathi eside nobunjiniyela obunembayo kunciphisa isidingo sokushintshwa nokugcinwa njalo, kwehlisa izindleko zokukhiqiza zizonke.

Isithwali se-epi pan siyingxenye ebalulekile yenqubo yokukhula kwe-epitaxial, ethonya ngokuqondile ikhwalithi nokuvumelana kwamadivayisi we-semiconductor. Ngokukhetha izinto ezifanele kanye nomklamo, abakhiqizi bangalungiselela inqubo ye-epitaxial, okuholela ekusebenzeni okuthuthukisiwe kwedivayisi nokunciphisa izindleko zokukhiqiza. Njengoba isidingo semishini kagesi ethuthukisiwe sikhula, ukubaluleka kwekhwalithi ephezuluepi pan abathwaliembonini ye-semiconductor iyaqhubeka nokukhula.
