Njira Yopangira Purosesa ya Smartphone Yogwira Ntchito Kwambiri
Purosesa ndi chimodzi mwa zinthu zofunika kwambiri pa foni yam'manja. Popanda purosesa yogwira ntchito bwino, chipangizochi sichingathe kuyendetsa mapulogalamu ndi ntchito zosiyanasiyana zapamwamba zomwe timakonda masiku ano. M'nkhaniyi, tifufuza njira zopangira purosesa ya foni yam'manja yogwira ntchito bwino, kuyambira pakupanga mpaka kupanga zinthu zambiri.
1. Kafukufuku ndi Chitukuko
Gawo loyamba popanga purosesa ya mafoni a m'manja ndi kafukufuku ndi chitukuko (R&D). Pa gawoli, mainjiniya ndi asayansi amasonkhana pamodzi kuti apange kapangidwe ka purosesa komwe kakugwirizana ndi zofunikira pakugwira ntchito bwino komanso kugwiritsa ntchito mphamvu moyenera. Njirayi imaphatikizapo kuyerekezera kwa makompyuta kuti apange mapangidwe osiyanasiyana ndikulosera momwe purosesa imagwirira ntchito komanso kudalirika kwake.
Pa gawo la R&D, zina mwazinthu zazikulu zomwe zaganiziridwa ndi izi:
– Kugwira ntchito kwa CPU (Central Processing Unit): Liwiro la purosesa popereka malangizo pa sekondi, nthawi zambiri limayesedwa mu Gigahertz (GHz).
– Kugwira ntchito kwa GPU (Graphics Processing Unit): Kutha kukonza zithunzi, ndikofunikira kwambiri pakujambula masewera ndi mapulogalamu a multimedia.
- Kugwiritsa ntchito mphamvu moyenera: Kumachepetsa kugwiritsa ntchito mphamvu kuti batire ikhale ndi moyo wautali.
- Kuphatikiza zinthu zina: Monga luntha lochita kupanga (AI), kuphunzira kwa makina, ndi kulumikizana kwa 5G.
Zatsopano mu njira zopangira zinthu ndi gawo lofunikira kwambiri pa njirayi, monga kugwiritsa ntchito ukadaulo wopanga wa 5nm kapena 3nm, zomwe zimathandiza kuti pakhale zida zazing'ono komanso zogwiritsa ntchito mphamvu zambiri.
2. Kapangidwe ndi Kuyerekeza
Lingaliro loyambira la purosesa likadziwika, gawo lotsatira ndikupanga ma circuitry a microelectronic a purosesa. Opanga zamagetsi amagwiritsa ntchito pulogalamu ya CAD (Computer-Aided Design) kuti apange kapangidwe ka ma transistors, ma circuitry, ndi zigawo zina pa chip.
Kapangidwe kameneka kamatsimikiziridwa kudzera mu ma simulation a pakompyuta kuti zitsimikizire kuti dera likugwira ntchito molingana ndi zomwe likufuna. Njirayi imatenga nthawi yayitali, chifukwa njira iliyonse ndi transistor ziyenera kufufuzidwa kuti zipewe zolakwika zomwe zingayambitse zolakwika kapena kuwonongeka kwa purosesa.
3. Kupanga Zigoba ndi Kujambula Zithunzi
Kapangidwe ka purosesa kakavomerezedwa, gawo lotsatira ndi kupanga chigoba. Chigoba ndi chitsanzo kapena nkhungu yomwe imagwiritsidwa ntchito popanga njira yojambulira zithunzi kuti ipange mawonekedwe pa wafer ya silicon. Njirayi imaphatikizapo masitepe angapo:
– Kupanga Chigoba: Kupanga chithunzi cha kapangidwe ka chip pogwiritsa ntchito zinthu za photomask.
– Chophimba: Ma wafer a silicon amapakidwa ndi chinthu choteteza kuwala chotchedwa photoresist.
– Kuwonekera: Chigoba chimayikidwa pamwamba pa wafer, ndipo mbali zina za wafer zimawonetsedwa ku kuwala kwa ultraviolet (UV), zomwe zimapangitsa kuti pakhale mawonekedwe a circuit.
- Kukula: Choletsa kuwala kwa dzuwa chomwe chimapezeka ku kuwala kwa UV chimatsukidwa, zomwe zimasiya mawonekedwe a circuit pa wafer.
4. Njira Yopangira Ma Wafer
Ma wafer a silicon ndi zinthu zofunika kwambiri zomwe ma processor amapangira. Ma wafer amenewa amapangidwa kuchokera ku ma crystals a silicon oyeretsedwa ndipo amapangidwa kukhala ma discs opyapyala. Njira yopangirayi imafuna njira zingapo, kuphatikizapo kusungunula ma crystals a silicon ndikudula m'magawo oonda kwambiri a wafer (omwe ali ndi ma millimeters ochepa okha).
Pakupanga ma wafer, zigawo za zinthu (monga silicon, oxides, ndi ma polima) zimawonjezedwa kudzera mu njira zoyika ndi kupukuta kuti apange kapangidwe ka microelectronic mkati mwa chip.
5. Kupaka Mankhwala Osokoneza Bongo ndi Kupanga Ma Transistor Structures
Ma transistors ndi zinthu zofunika kwambiri pa purosesa iliyonse. Kudzera mu njira yotchedwa ion implantation kapena doping, ma ion enaake amaikidwa mu silicon wafer kuti asinthe mphamvu zake zamagetsi, zomwe zimathandiza kuti transistor igwire ntchito ngati switch yomwe ingalamulire kuyenda kwa magetsi.
Njirayi ndi yolondola kwambiri, pogwiritsa ntchito njira zapamwamba monga extreme ultraviolet (EUV) lithography kuti apange ma transistors ang'onoang'ono kwambiri, mpaka ma nanometer ochepa chabe.
6. Kusonkhanitsa ndi Kuyika
Wafer ikakonzedwa ndipo ma transistors apangidwa, gawo lotsatira ndikugawa wafer m'ma chips osiyanasiyana, otchedwa dies. Kenako ma dies amenewa amayesedwa kuti atsimikizire kuti amagwira ntchito bwino komanso kuti ndi odalirika asanayikidwe mu phukusi lalikulu la purosesa.
Kuyika ma chip kumaphatikizapo kuyika die pa substrate, yomwe imayikidwa mu phukusi la pulasitiki, ceramic, kapena chitsulo kuti iteteze chip ndikuchilumikiza ku bolodi lamagetsi mkati mwa foni yam'manja.
7. Kuyesa ndi Kutsimikizira
Ma processor asanayambe kugwiritsidwa ntchito m'mafoni a m'manja, ayenera kuyesedwa mozama kwambiri. Kuyesaku kumakhudza zinthu zosiyanasiyana monga:
- Magwiridwe antchito: Amaonetsetsa kuti purosesa ikugwira ntchito pa liwiro lomwe mukufuna popanda kutentha kwambiri.
– Kudalirika: Kumayesa kulimba kwa purosesa m'malo osiyanasiyana owopsa.
- Kugwirizana: Kuonetsetsa kuti purosesa ikhoza kugwira ntchito bwino ndi zida zina zamakina ndi mapulogalamu omwe ali mu chipangizocho.
8. Kupanga Zinthu Zambiri
Purosesa ikadutsa mayeso onse, kupanga zinthu zambiri kumatha kuyamba. Njira yopangira imagwiritsa ntchito zida ndi njira zodzipangira zokha kuti ipange ma processor mayunitsi zikwizikwi mpaka mamiliyoni mwezi uliwonse. Mafakitale opanga ma processor amenewa nthawi zambiri amatchedwa ma foundry.
Makampani otsogola opanga zinthu monga TSMC (Taiwan Semiconductor Manufacturing Company) ndi Samsung akutsogolera makampani opanga zinthu pogwiritsa ntchito ukadaulo wosintha nthawi zonse, kuonetsetsa kuti ma processor a mafoni a m'manja akupitilizabe kukhala patsogolo pa luso lamakono.
9. Kuphatikiza mu Smartphone
Gawo lomaliza pakupanga mapurosesa ndi kulumikizidwa mu foni yam'manja. Opanga mafoni am'manja, monga Apple, Samsung, ndi Xiaomi, amapeza mapurosesa awa ndikuwaphatikiza ndi zinthu zina monga kukumbukira, ma module olumikizirana, zowonetsera, ndi mabatire mu mapangidwe a zida zawo.
Njira yolumikizirayi imafunanso kuyesedwa kwina pamlingo wa makina kuti zitsimikizire kuti zigawo zonse zimagwira ntchito bwino ndipo sizimayambitsa mavuto monga kutentha kwambiri kapena kusakhazikika kwa makina.
Mapeto
Njira yopangira purosesa ya foni yam'manja yogwira ntchito bwino kwambiri ndi njira yayitali komanso yovuta, yokhala ndi magawo angapo, kuyambira pa kafukufuku ndi chitukuko mpaka kupanga, kuyesa, komanso kupanga zinthu zambiri. Gawo lililonse limafuna ukadaulo wapamwamba komanso ukatswiri kuti purosesa yomwe yatuluka ikwaniritse zosowa za ogula zomwe zikuchulukirachulukira.
Chifukwa cha kufunikira kwakukulu kwa zinthu zapamwamba komanso kulumikizana mwachangu, tsogolo la ma processor a mafoni likuwoneka lowala komanso lodzaza ndi kuthekera. Zatsopano zatsopano ndi ukadaulo wopanga zinthu zipitilizabe kupititsa patsogolo magwiridwe antchito ndi magwiridwe antchito, zomwe zingathandize mbadwo wotsatira wa mafoni a m'manja kupereka zokumana nazo zodziwika bwino kwa ogwiritsa ntchito.
