Masana'antun Wafer na China, Masu Kaya, Masana'anta
Menene wafer ɗin semiconductor?
Wafer na semiconductor wani yanki ne mai sirara, zagaye na kayan semiconductor wanda ke aiki a matsayin tushen ƙera da'irori masu haɗawa (ICs) da sauran na'urorin lantarki. Wafer ɗin yana samar da wuri mai faɗi da daidaito wanda aka gina sassa daban-daban na lantarki a kai.
Tsarin kera wafer ya ƙunshi matakai da dama, ciki har da haɓaka babban lu'ulu'u ɗaya na kayan semiconductor da ake so, yanke lu'ulu'u zuwa siririn wafers ta amfani da zare lu'u-lu'u, sannan gogewa da tsaftace wafers ɗin don cire duk wani lahani ko ƙazanta a saman. Wafers ɗin da ke fitowa suna da saman da yake da faɗi sosai kuma mai santsi, wanda yake da mahimmanci ga ayyukan ƙera su na gaba.
Da zarar an shirya wafers ɗin, suna yin jerin hanyoyin ƙera semiconductor, kamar photolithography, etching, deposition, da doping, don ƙirƙirar tsare-tsare masu rikitarwa da ake buƙata don gina abubuwan lantarki. Waɗannan tsare-tsare ana maimaita su sau da yawa akan wafer ɗaya don ƙirƙirar da'irori masu haɗawa da yawa ko wasu na'urori.
Bayan an kammala aikin ƙera, ana raba guntun ta hanyar yanke wafer ɗin a kan layukan da aka riga aka tsara. Sannan ana naɗe guntun da aka raba don kare su da kuma samar da haɗin lantarki don haɗawa cikin na'urorin lantarki.
Abubuwa daban-daban akan wafer
Ana yin wafers na Semiconductor galibi daga silicon mai lu'ulu'u ɗaya saboda yawansa, kyawawan halayen lantarki, da kuma dacewa da tsarin ƙera semiconductor na yau da kullun. Duk da haka, dangane da takamaiman aikace-aikace da buƙatu, ana iya amfani da wasu kayan don yin wafers. Ga wasu misalai:
Silicon carbide (SiC) wani abu ne mai faɗi na semiconductor wanda ke ba da kyawawan halaye na zahiri idan aka kwatanta da kayan gargajiya. Yana taimakawa rage girman da nauyin na'urori daban-daban, kayayyaki, har ma da tsarin gaba ɗaya, yayin da yake inganta inganci.
Muhimman Halaye na SiC:
- - Faɗin Bandgift:Bandgap na SiC ya ninka na silicon sau uku, wanda hakan ke ba shi damar aiki a yanayin zafi mafi girma, har zuwa 400°C.
- - Babban Filin Rage Matsalolin da ke Gabatarwa:SiC na iya jure wa har sau goma na filin lantarki na silicon, wanda hakan ya sa ya dace da na'urori masu ƙarfin lantarki mai yawa.
- -Babban Mai Gudanar da Zafi:SiC yana wargaza zafi yadda ya kamata, yana taimaka wa na'urori su kula da yanayin zafi mafi kyau da kuma tsawaita rayuwarsu.
- - Babban Saurin Drift na Electron Mai Cikewa:Tare da ninki biyu na saurin karkatar da silicon, SiC yana ba da damar yin amfani da mitoci masu canzawa mafi girma, yana taimakawa wajen rage girman na'urori.
Aikace-aikace:
-
- Lantarki Mai Lantarki:Na'urorin wutar lantarki na SiC sun yi fice a yanayin wutar lantarki mai ƙarfi, wutar lantarki mai ƙarfi, zafin jiki mai yawa, da kuma yanayin mita mai yawa, wanda hakan ke ƙara inganta yadda ake canza makamashi. Ana amfani da su sosai a cikin motocin lantarki, tashoshin caji, tsarin hasken rana, jigilar jirgin ƙasa, da kuma hanyoyin sadarwa masu wayo.
-
- Sadarwar Microwave:Na'urorin GaN RF da ke tushen SiC suna da matuƙar muhimmanci ga kayayyakin more rayuwa na sadarwa mara waya, musamman ga tashoshin tushe na 5G. Waɗannan na'urori suna haɗa kyakkyawan yanayin zafi na SiC tare da fitowar RF mai ƙarfi da mita mai yawa na GaN, wanda hakan ya sa suka zama zaɓi mafi kyau ga hanyoyin sadarwa na zamani masu mita mai yawa.
Gallium nitride (GaN)wani abu ne na semiconductor mai faɗi na ƙarni na uku wanda ke da babban bandgap, babban ƙarfin lantarki na zafi, saurin juyewar electrons mai yawa, da kuma kyakkyawan halayen filin fashewa. Na'urorin GaN suna da fa'idodin amfani mai faɗi a cikin manyan wurare masu ƙarfi, sauri, da manyan iko kamar hasken LED mai adana makamashi, nunin laser, motocin lantarki, grid mai wayo, da sadarwa ta 5G.
Gallium arsenide (GaAs)wani abu ne na semiconductor wanda aka sani da yawan mitarsa, yawan motsi na electron, yawan fitarwa mai ƙarfi, ƙarancin hayaniya, da kuma kyakkyawan layi. Ana amfani da shi sosai a masana'antar optoelectronics da microelectronics. A cikin optoelectronics, ana amfani da substrates na GaAs don ƙera LED (diodes masu fitar da haske), LD (diodes na laser), da na'urorin photovoltaic. A cikin microelectronics, ana amfani da su wajen samar da MESFETs (transistors na filin ƙarfe-semiconductor), HEMTs (transistors masu motsi na electron masu girma), HBTs (transistors na bipolar heterojunction), ICs (da'irori masu haɗawa), microwave diodes, da na'urorin tasirin Hall.
Indium phosphide (InP)yana ɗaya daga cikin mahimman na'urorin semiconductor na III-V, wanda aka sani da ƙarfin motsin lantarki, juriya ga radiation mai kyau, da kuma faɗin bandgip. Ana amfani da shi sosai a masana'antar optoelectronics da microelectronics.
Nemi Fa'idar Wafer
Aiko mana da kayan wafer ɗinka, diamita, kauri, nau'in conductivity, juriya, yanayin lu'ulu'u, buƙatun saman da yawa. Semicera zai sake duba tsarin da aka buƙata kuma ya ba da tallafin zaɓin samfura da ambato bisa ga ƙayyadaddun bayanai da ake da su.
