Fasahar Ƙirƙirar Chip don Wayoyin Salula
Pendahuluan
Fasahar ƙera guntu ita ce ginshiƙin juyin juya halin fasaha da muke fuskanta a yanzu, musamman a duniyar wayoyin salula. Kowace wayar salula ta zamani tana dogara ne da guntu mai matuƙar inganci don samar da ayyuka iri-iri, tun daga sadarwa zuwa sarrafa hotuna. Wannan labarin zai binciki fannoni daban-daban na fasahar ƙera guntu, yadda ake haɓaka waɗannan guntu, da kuma yadda suke ba da gudummawa ga ci gaban wayoyin salula.
Tarihin Farko da Ci Gaba
ƙera guntu, wanda aka fi sani da masana'antar semiconductor, ya fara ne da ƙirƙirar transistor a shekarar 1947 ta hannun John Bardeen, Walter Brattain, da William Shockley a Bell Labs. Wannan gano ya share fagen rage yawan na'urorin lantarki. A shekarar 1958, Jack Kilby na Texas Instruments ya yi nasarar ƙirƙirar da'irar haɗin gwiwa ta farko, wadda ta zama tushen guntu ta zamani.
A tsawon lokaci, fasahar ƙera guntu ta ci gaba. Gordon Moore, ɗaya daga cikin waɗanda suka kafa Intel, ya yi hasashen a shekarar 1965 cewa adadin transistor ɗin da ke kan guntu zai ninka sau biyu a kowace shekara biyu, wani hasashen da daga baya aka sani da Dokar Moore. Wannan hasashen ya tabbatar da gaskiya har zuwa yau, yana haifar da ƙirƙira mai ban mamaki a fannin ƙera guntu.
Fasahar Ƙirƙirar Ƙirƙirar Ƙirƙirar Zamani
Tsarin Litography
Lithography shine mafi mahimmancin mataki a cikin ƙera guntu. Ya ƙunshi amfani da hasken haske ko hasken lantarki don rubuta tsarin da'ira akan wafers na silicon. A cikin fasahar zamani, ana amfani da lithography mai tsauri na ultraviolet (EUV) don cimma babban ƙuduri, yana ba da damar ƙera guntu tare da transistor kamar ƙananan nanometers 5 (nm) ko ma ƙarami. Wannan yana ba da damar haɗa ƙarin transistor akan guntu ɗaya, yana ƙara aiki da rage amfani da wutar lantarki.
Ajiyewa da Gyaran Kaya
Bayan tsarin lithography, matakai na gaba sune adanawa, inda aka ajiye kayan aiki a kan wafer, da kuma yin etching, inda aka cire kayan da ba a so, wanda ke ƙirƙirar tsarin da'irar da ake so. Ana gudanar da waɗannan hanyoyin da kyau ta amfani da kayan aiki masu inganci.
Ion Implantation
Dasa ion wata dabara ce da ake hanzarta ions a cikin wani silicon wafer don canza halayen lantarki na wasu yankuna. Ana amfani da wannan dabarar don sarrafa nau'in da yawan masu ɗaukar caji a cikin transistor, wanda yake da mahimmanci ga aikin guntu.
Haɗi da Marufi
Da zarar an samar da transistors da sauran sassan, mataki na gaba shine a haɗa su da juna ta hanyar wani tsari da ake kira haɗin kai. Sabbin fasahohin marufi na guntu, kamar su 3D stacking, suna ba da damar haɗa layuka da yawa na circuits a cikin ƙaramin sarari, yana ƙara inganci da aiki.
Aikace-aikace a cikin Wayar Salula
Mai sarrafawa
Injin sarrafa kwamfuta shine kwakwalwar wayar salula. Ana ƙera na'urori masu sarrafa kwamfuta na zamani kamar Qualcomm Snapdragon, Apple A-series, da Samsung Exynos ta amfani da fasahar ƙera guntu ta zamani. Waɗannan na'urori masu sarrafa kwamfuta galibi suna da cores na CPU da yawa, GPU, da sauran na'urori masu sarrafawa na musamman kamar NPU (Neural Processing Unit) don fasahar wucin gadi.
Ƙwaƙwalwar ajiya
Ana ƙera ƙwaƙwalwar ajiya, ko RAM (Random Access Memory) ko kuma ajiyar ciki ta hanyar amfani da fasahar NAND flash, kuma ana ƙera ta ne ta amfani da dabarun ƙera guntu. Saurin ƙwaƙwalwa da ƙarfinsa suna tasiri sosai ga aikin wayar salula gaba ɗaya.
Modems da Abubuwan RF
Sadarwa muhimmin abu ne na wayoyin komai da ruwanka, wanda ke buƙatar fasahar ƙera guntu ta zamani don ƙirƙirar modems da sauran sassan mitar rediyo (RF). Fasaha kamar 5G tana gabatar da ƙalubalen ƙera abubuwa mafi girma, suna buƙatar ƙarin daidaito da inganci.
Na'urar haska bayanai
Wayoyin zamani na zamani suna da na'urori masu auna firikwensin iri-iri, kamar kyamarori, na'urorin auna firikwensin, na'urorin auna firikwensin yatsa, da na'urorin auna firikwensin yatsa. Duk waɗannan na'urori masu auna firikwensin an ƙera su ne ta amfani da dabarun ƙera guntu na zamani.
Kalubale a Fasahar Ƙirƙirar Chip
Sikelin Nanometer
Yayin da girman transistor ke ci gaba da raguwa zuwa sikelin nanometer, ƙalubalen ƙira suna ƙaruwa. Ana buƙatar daidaito a matakin atomic don tabbatar da ingantaccen aikin guntu. Ƙaramin rashin daidaito na iya haifar da matsala.
Babban Kuɗi
Kayan aikin ƙera guntu, waɗanda aka sani da masana'anta, suna da tsada sosai don ginawa da aiki. Kamfanoni kaɗan ne kawai, kamar TSMC, Samsung, da Intel, ke da iko da albarkatun samar da guntu mafi ci gaba.
Sabbin Kayan Aiki
Ana binciken sabbin kayayyaki kamar graphene da molybdenum disulfide don shawo kan iyakokin silicon na gargajiya. Duk da haka, waɗannan sabbin kayan suna gabatar da ƙalubale na musamman na ƙera kayayyaki, suna buƙatar sabbin hanyoyi da fasahohi don samarwa.
Makomar Fasahar Ƙirƙirar Chip
Kaddara sarrafawa
Wata hanya ta gaba ita ce haɓaka kwamfutocin quantum, waɗanda ke amfani da qubits maimakon bits na gargajiya. Wannan yana buƙatar sabuwar hanyar ƙirƙira gaba ɗaya.
Fasahar Litography Mai Ci Gaba
Ana sa ran ƙarin ci gaba a fasahar lithography zai ba da damar ƙera kwakwalwan kwamfuta masu ƙananan girman transistor, wataƙila ma ƙasa da 1 nm.
Kwamfutoci masu Ayyuka na Musamman
Nan gaba, wataƙila za mu ga ƙarin kwakwalwan kwamfuta da aka tsara don ayyuka na musamman kamar fasahar wucin gadi, nazarin manyan bayanai, da fasahar IoT. Wannan zai buƙaci ƙirƙirar guntu mai zurfi da ƙwarewa.
Kammalawa
Ci gaban da aka samu a fasahar ƙera guntu ya kasance babban abin da ke haifar da ci gaban wayoyin salula da muke jin daɗinsu a yau. Tun daga tsarin lithography mai inganci zuwa amfani da sabbin kayayyaki da ƙalubalen da za a fuskanta a nan gaba, fasahar ƙera guntu za ta ci gaba da bunƙasa don biyan buƙatun da ke ƙaruwa koyaushe. Saboda haka, ƙera guntu ba wai kawai ginshiƙin fasahar wayar salula ba ne, har ma da makomar sabbin fasahohin zamani.
