Ngā mowhiti arotahi paninga CVDHe mahi nui tā rātou i roto i te whakairo haurua-ā-ira hou mā te whakau i ngā rohe plasma me te whakarite kia ōrite te tohatoha katote puta noa i te anga. E whakamārama ana tēnei tuhinga he aha i hira ai rātou mō ngā pūnga matatau, e whakaatu ana i ō rātou pānga ki te ōritetanga o te whakairo, te whakahaere CD, te whakaiti i te poke, me te hua tukanga whānui.
Ⅰ. Mai i te Whakairo Plasma ki te Hangarau Mowhiti Arotahi
Ko te whakairo plasma tētahi o ngā hangarau tauira tino hira i roto i te hanga semiconductor hou, e āhei ai te waihanga i ngā āhuatanga nanoscale e hiahiatia ana mō ngā taputapu arorau me te mahara matatau. I te mea kei te heke haere tonu ngā pona hangarau i raro i te 10 nanometer, ā, kei te whanake haere ngā hoahoa taputapu ki ngā hanganga FinFET me Gate-All-Around (GAA), kua tino heke te manawanui mō ngā rerekētanga tukanga. I ēnei rā, me whakahaere ngā tawhā pēnei i te ōritetanga whakairo, te whakahaere i te taha whakahirahira (CD), me te kiato hapa me te tika tata-atomika.
Ahakoa te aro nui o te arotautanga tukanga ki te matū plasma, te mana auau reo irirangi (RF), me te hoahoa rūma, he mea nui tonu—engari he iti ake te kitea—ko te whakahaere i ngā āhuatanga rohe i ngā taha o te wafer. Koinei tonu te wāhi e whai wāhi nui ai te mowhiti arotahi. Kei te taha o te wafer i runga i te chuck hiko (ESC), ka mahi te mowhiti arotahi hei whakarerekē rohe, ka huri i te mara hiko ā-rohe, ka whakau i te hipoki plasma, me te whakarite kia tohatohahia te katote puta noa i te mata wafer katoa.
I roto i ngā taiao whakairo matatau, kua noho ngā mowhiti arotahi kua pania ki te matū whakapūtanga kohu (CVD) hei paerewa ahumahi nā ō rātou āhuatanga rauemi pai rawa atu. Ehara i te mea he mea pau noa iho ēnei wāhanga; he mata hanga-tika e pā tika ana ki te whanonga plasma, te pumau o te tukanga, ā, i te mutunga ka whakatau i te hua o te taputapu.
Tuarua. He aha te Hiranga o ngā Mowhiti Arotahi mō te Whakairo Tika-Teitei
I roto i ngā pūnaha whakairo plasma, ka whakaatuhia e ngā taha wafer he koretake i roto i ngā āhuatanga āhuahanga me ngā āhuatanga rohe hiko. Ki te kore he mehua whakatikatika tika, ka arahi tēnei koretake ki ngā hapa nui o te mara hiko me te papa plasma, ka puta te mea e kiia nei ko te "pānga taha". Ka puta tēnei pānga hei koki taunga katote kore-taurite me ngā rerekētanga o te mātotoru rere katote, ka hua ake he rerekētanga o ngā tere whakairo me ngā kōtaha whakairo tata ki te taha wafer.
E whakaatu ana ngā rangahau whakamātautau me ngā rangahau ariā, i te korenga o ngā hanganga whakakapi taha, ka noho te rohe e toro atu ana i ētahi mirimita ki roto mai i te taha papatahi hei rohe taha kore e taea¹. Mō ngā pūnga hangarau matatau, ina nui te rahi o ngā maramara, ā, he tino kikī ngā tawhē tukanga, kāore e whakaaetia ana taua ngaronga rohe i te taha ōhanga.
Mā te whakaurunga o tētahi mowhiti arotahi ka whānui ake te rohe plasma ki tua atu i te taha tūturu o te wafer, ā, ka hangaia he hanganga pūeru ōrite ake. Mā te whakarato i tētahi taiao hiko me te taiao e whakahaeretia ana, ka whakarite te mowhiti arotahi kia noho ōrite tonu ngā ara o ngā katote puta noa i te mata wafer katoa. He mea nui tēnei hei whakatutuki i ngā taumata ōrite e hiahiatia ana e te hanga papatipu hou; i roto i ēnei taiao hangahanga, ko te whāinga mō te ōritetanga o te whakairo i roto i te wafer ka whakatakotoria i roto i te whānuitanga o te ±2%.
Hei tāpiri atu, mā te whakau i ngā āhuatanga rohe o te rūma puta noa i ngā anga rerekē, ka āwhina te mowhiti arotahi ki te whakapai ake i te auautanga o te tukanga. I roto i ngā taiao hangahanga tere-whakaputa, ahakoa ngā piki me ngā heke iti o ngā āhuatanga taha ka arahi pea ki te nekenekehanga o te tukanga; nō reira, he mea tino nui te pumau o te mahi mowhiti arotahi.
Ⅲ. Te Uara Matua o ngā Paninga CVD
I te mea ka nui haere te tono mō ngā tukanga whakairo plasma—ina koa te whānui o te whakamahinga o ngā tukanga matū e hangai ana ki te fluorine me te chlorine—kua tino kaha ake hoki ngā whakaritenga rauemi mō ngā mowhiti arotahi. Ko ngā rauemi tuku iho pēnei i te quartz, i te uku papatipu rānei, he maha ngā wā ka pāngia e te tere whakairo teitei, te āhua ki te whakaputa matūriki, me te kore pumau i raro i te whakamahinga plasma mō te wā roa. Ko ngā paninga CVD—ina koa ko te CVD SiC (silicon carbide) me ngā paninga waro CVD—ka kaha ki te wikitoria i ēnei herenga nā ō rātou hanganga moroiti me ngā āhuatanga matū ahurei.
Ko tētahi āhuatanga matua o ngā paninga CVD ko tōna tino matotoru, e tata ana ki te matotoru ariā, me tōna tino iti o te porosity, e tino whakarei ake ana i tōna ātete ki te whakairo i puta mai i te plasma. Kua whakaatuhia e ngā rangahau② i roto i te taiao plasma e ahu mai ana i te fluorine, ko te tere whakairo o te CVD SiC he iti noa iho i tērā o te quartz, he mea tino pai mō ngā tukanga whakairo roa, kaha-teitei. Ko te pikinga o te pakari ka hua ake he roa ake te roa o te oranga o ngā wāhanga me te whakaiti i te auau tiaki.
He rite tonu te hiranga o te take o te whakahaere poke. Ko ngā matūriki i hangaia e ngā wāhanga rūma mahi tetahi o ngā tino take o te ngaronga o te hua i roto i ngā tukanga hanga semiconductor matatau. E ai ki ngā paerewa SEMI me ngā rangahau whakahaere poke e tika ana, ahakoa ngā matūriki iti-micron ka taea te whakaputa i ngā hapa nui, inā koa i roto i ngā pūnga tukanga matatau i raro i te 10 nanometer. Ko ngā paninga CVD, me ō rātou āhuatanga mata matotoru me te pumau, ka whakaiti nui i te mōrearea o te moroiti-papaki o te mata me te tukunga poke, ā, ka āwhina i te hanga i tētahi taiao tukanga ma me te whakapai ake i te hua.
Kiriata Kiriata SiC CVD me te Hanganga Moroiti
Ko tētahi atu āhuatanga nui ko te whakahaere i te tukunga irahiko tuarua (SEE). He kaha te awe o ngā āhuatanga SEE ki te taunekeneke i waenga i te parāma me te mata o te rūma, ā, ka pā tēnei ki te kiato me te pumau o te parāma. Ki te whakatauritea ki ngā rauemi tuku iho, he rite tonu, he matapae ake ngā āhuatanga SEE o ngā mata kua pania ki te CVD, e āhei ai te whakahaere tika ake i ngā āhuatanga o te parāma, me te whakapai ake i te auautanga o te tukanga.
Ko te pumau o te wera tētahi atu painga matua o ngā paninga CVD. He maha ngā wā ka puta he kawenga wera nui mai i ngā tukanga plasma kiato-teitei, inā koa i ngā rohe taha o te wafer. He pai rawa te kawe wera o ngā rauemi pēnei i te CVD SiC me ngā āhuatanga whakawhānui wera ka taea te whakahaere, ka whakaiti i te tūponotanga o te ngatata, te piko, te wehewehe rānei i raro i te ahotea wera hurihuri. He mea nui tēnei hanganga kia mau tonu ai te mahi puta noa i ngā huringa tukanga roa.
Ⅳ. Pānga ki ngā Inenga Mahi Whakairo Matua
Mowhiti Arotahi Paninga CVD Whakauru
Ka pā tika, ka taea hoki te ine i tēnei mowhiti arotahi ki ngā inenga mahi matua maha i roto i ngā tukanga whakairo haurua-ira. Ko tētahi o ngā inenga tino nui ko te ōritetanga o te whakairo. Mā te whakau i te papa plasma me te whakarite kia ōrite te tohatoha rere katote, ka taea e ngā mowhiti arotahi kua pania ki te CVD te whakahaere tino tika i te ōritetanga whānui o te wafer, e tutuki ai te ±2% te tika e hiahiatia ana mō te hanga taputapu matatau. He mea tino nui tēnei taumata whakahaere mō ngā tukanga whakairo ōwehenga āhuatanga teitei, i reira ahakoa he iti noa ngā rerekētanga ka arahi ki te he o te kōtaha whakairo nui.
Mana Whakahaere Ahu Matua (CD)
Ka taea e ngā rerekētanga o ngā koki taunga katote i ngā taha o te papa wafer te whakaputa i ngā rerekētanga CD, ā, ka piki haere te uaua o tēnei take i te mea ka haere tonu te whakaiti i ngā rahi o ngā āhuatanga. Mā te pupuri i ngā āhuatanga o te mara hiko ōrite, ka āwhina te mowhiti arotahi ki te whakarite i te ōritetanga o ngā ara katote, ā, ka whakaiti i ngā rerekētanga CD puta noa i te papa wafer katoa. He mea nui tēnei mō te pupuri i te mahi a te taputapu me te whakatutuki i ngā whakaritenga hoahoa i ngā pūnga tukanga matatau.
Te Whakapai Ake i te Pūmautanga me te Whakahokinga o te Tukanga
Ka whakaratohia e ngā paninga CVD he mata pumau, he pakari hoki, ā, ka mau tonu ōna āhuatanga i te roanga o te wā, ka whakaiti i te nekehanga o te āhua o te plasma, ā, ka taea ai te mahi pumau ake puta noa i ngā papa. I roto i ngā taiao hanga nui-rahi, he mea nui tēnei mō te whakatinana i te Mana Tukanga Tatauranga (SPC).
Te Mahi Whakahaere Matūriki Whakarei Ake
Mā te whakaiti i te kakahu me te whakapai ake i te āhua o te mata ka whakaitihia te whakaputanga matūriki, ka pā tika tēnei ki te hua me te pono o te taputapu. I roto i te hanga semiconductor matatau, he tino kaha ngā whāinga whakahaere kiato hapa, he nui noa iho tēnei painga hei whakamana i te tango i ngā wāhanga kua pania ki te CVD.
I te mea kei te piki haere tonu ngā tono a te umanga haurua-waea mō te tika o te whakahaere tukanga me te mahi rauemi, ko te whanaketanga me te tuku oNgā mowhiti arotahi kua pania ki te CVDkei te piki haere te kohikohinga i roto i ētahi kaihanga motuhake, e ārahihia ana e te hangarau.
