Darajar Musamman ta Micropowder Mai Koren Silicon Carbide a Masana'antar Semiconductor
Masana'antar semiconductor koyaushe tana da alaƙa da fasahar zamani, inda mutane kan tattauna batutuwa masu inganci kamar na'urorin daukar hoto da ƙirar guntu. Duk da haka, a cikin wannan masana'antar, wasu kayayyaki marasa mahimmanci suna taka muhimmiyar rawa.Micropodar silicon carbide mai launin koreɗaya ne daga cikin irin waɗannan kayan. A yau, bari mu tattauna wannan kayan na musamman, a hankali yana aiki ta hanyar kera semiconductor.
Bari in fara da wani labari mai ban sha'awa. A bara, na halarci wani baje kolin kasuwanci na masana'antar semiconductor. A wani rumfar da ba ta da wani abin burgewa, injiniyoyi da yawa suna tattaunawa da wani kayan niƙa mai daɗi. Ina sauraro sosai, na ji suna ta ambaton "ƙananan silicon carbide micropowder." Na yi mamaki a lokacin; yana kama da na gargajiya na goge masana'antu, to ta yaya za a iya haɗa shi da semiconductor daidai? Daga baya, na fahimci cewa a wannan masana'antar, yayin da kayan suka fi sauƙi, haka ma suke da mahimmanci.
Menene ainihin ma'aunin foda na silicon carbide kore? A taƙaice dai, abu ne da aka yi da ɗan adam, wanda aka narkar a cikin tanda mai zafi mai zafi daga kayan da aka yi da kayan ƙasa kamar su quartz yashi da petroleum coke. Ya samo sunansa ne daga tsarkinsa mai girma da launin kore mai ban mamaki. Kada ku raina waɗannan ƙananan ƙwayoyin; taurinsu ya fi na lu'u-lu'u, duk da haka suna da ingantaccen kwanciyar hankali da rashin kuzarin sinadarai.
A cikin masana'antar semiconductor, madaidaicin wafer yana ƙayyade yawan guntu. Wannan yana kawo mu ga babban ƙwarewarkore silicon carbideMicropowder: gogewar sinadarai ta injiniya (CMP). Lao Zhang, injiniyan tsari a wani kamfanin wafer fab, ya yi amfani da wani misali mai haske: "Yana kama da ba wafer 'maganin fuska'—sassauta kumbura da rashin daidaito ba tare da barin karce ba. Micropowder ɗin silicon carbide mai launin kore yana kama da ƙwayoyin microcrystalline a cikin kula da fata na sama - mai laushi amma mai tasiri." Hakika, a cikin kera guntu, har ma da ƴan goma na micron na rashin daidaito na iya haifar da gajeriyar hanya ko buɗewa.
Gudanar da zafi babban ƙalubale ne a masana'antar semiconductor. Yayin da haɗa guntu ke ƙaruwa, watsar da zafi yana ƙara bayyana.Micropodar silicon carbide mai launin koreyana da ƙwarewa ta musamman a wannan fanni: ƙara shi a cikin kayan da ke amfani da zafi yana inganta zubar zafi sosai. Wani injiniyan zafi a wani sanannen kamfanin guntu ya gaya mini, "Yanzu muna amfani da wani ƙaramin foda na silicon carbide kore a cikin man shafawa mai zafi mai ƙarfi, wanda ke inganta ingancin watsa zafi da sama da 20%. Wannan shine ceton rai a cikin fasahar aiwatar da 5nm da 3nm."
Micropowder mai launin kore na silicon carbide ya fi zama dole a fannin kera kayan aikin semiconductor. Yawancin muhimman abubuwan da ke cikin injunan lithography da injunan etching, waɗanda za su iya kashe miliyoyin yuan, suna buƙatar daidaiton injina mai ƙarfi sosai. Misali, tsarin gani na injunan lithography yana buƙatar madaidaicin madubi mai ƙarfi, wanda ke buƙatar amfani da micropowder mai launin kore na silicon carbide dondaidaici nikaWani tsohon soja mai shekaru 20 na gwaninta ya ce, "Amfani da wannan kayan abu yana da matuƙar wahala. Girman ƙwayoyin cuta, yawansu, da ƙimar pH duk suna buƙatar a sarrafa su daidai; ko da ƙaramin karkacewa na iya shafar sakamakon ƙarshe."
Ya kamata a lura cewa tare da karuwar kayan semiconductor na ƙarni na uku, micropowder na silicon carbide mai launin kore ya sami sabon aiki. Na'urorin semiconductor masu tushen silicon carbide kansu suna buƙatar micropowder na silicon carbide mai launin kore don niƙa da gogewa yayin sarrafawa. Yana da zagaye mai ban sha'awa - amfani da silicon carbide don sarrafa silicon carbide. Daraktan fasaha na wani kamfanin sabbin kayan semiconductor ya yi murmushi ya ce, "Kamar amfani da lu'u-lu'u ne don yanke lu'u-lu'u; kamar yadda kayan za su iya fahimtar juna da gaske."
Foda mai launin kore na silicon carbide shima yana taka muhimmiyar rawa wajen kula da inganci. Masana'antun Semiconductor suna buƙatar kulawa akai-akai na kayan aiki, musamman tsaftace layukan jigilar kaya da ɗakunan amsawa. Saboda foda mai launin kore na silicon carbide ba ya aiki yadda ya kamata kuma baya haifar da sabbin gurɓatattun abubuwa, shine kayan da aka fi so don tsaftace hanyoyin tsaftacewa. Wani injiniyan gyara ya bayyana, "Idan aka kwatanta da sauran goge-goge,foda mai siffar silicon carbide koreba ya barin ions na ƙarfe a bangon ciki na kayan aiki, wanda yake da mahimmanci don kiyaye muhalli mai tsabta a cikin samar da guntu.
Ba shakka, kowane abu yana da damar ingantawa. Kalubalen da ake fuskanta a yanzu na micropowder mai launin kore na silicon carbide galibi yana cikin tsarin kula da farashi da daidaiton inganci. Tsarin samarwa mai rikitarwa da yawan amfani da makamashi yana taimakawa wajen hauhawar farashinsa. Bugu da ƙari, daidaito a cikin rukuni babban abin damuwa ne ga masu amfani. Duk da haka, manyan kamfanoni na cikin gida da yawa suna magance waɗannan matsalolin, suna rage gibin da ke tsakanin kayayyakin da aka shigo da su ta hanyar inganta hanyoyin samarwa da tsarin sarrafa inganci.
Idan aka yi la'akari da gaba, yayin da fasahar semiconductor ke ci gaba zuwa ƙananan matakai da kuma matakan haɗin kai mafi girma, buƙatar micropowder na silicon carbide kore zai ci gaba da ƙaruwa. Wannan gaskiya ne musamman a fannoni masu tasowa kamar kwakwalwan leƙen asiri na wucin gadi, kwakwalwan sadarwa na 5G, da kwakwalwan tuƙi masu sarrafa kansu, waɗanda ke sanya ƙarin buƙatu kan daidaiton sarrafawa da aikin watsa zafi. Wannan yana buɗe faffadan kewayon aikace-aikace don micropowder na silicon carbide kore.
Na tuna wani tsohon mai fasaha a masana'antar ya ce, "Masana'antar semiconductor kamar ƙanƙara ce. Abin da mutane ke gani kawai shine ƙirar guntu da ƙera manyan kayayyaki a saman saman, yayin da kayan aiki, hanyoyin aiki, da kayan aiki a ƙarƙashin saman sune tushen da ke tallafawa masana'antar gaba ɗaya." Micropowder mai launin kore na silicon carbide wani muhimmin sashi ne na waɗannan kayan tushe. Wataƙila ba zai zama mai jan hankali kamar injin lithography ba, amma waɗannan kayan "marasa gani" ne ke tallafawa ci gaban masana'antar semiconductor gaba ɗaya.
Lokaci na gaba da za ka yi amfani da wayar salula ko kuma ka tuka mota mai wayo, wataƙila ka yi la'akari da cewa a bayan waɗannan samfuran fasaha masu zurfi akwai gudummawar kayan da ba su da wani amfani kamar su micropowder na silicon carbide mai launin kore. Bayan haka, ci gaban kowace masana'antu ba zai iya rabuwa da waɗannan "jarumai marasa tunani" da ke ɓoye a bayan fage ba.
