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, ahakoa he iti noa ngā rerekētanga ka arahi ki te hē nui o te kōtaha whakairo.
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 Whakapūmautanga 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-ira 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.
