1.Moralo oa chip.

Mohato oa pele oa moralo, ho beha lipehelo

Mohato oa bohlokoa ka ho fetesisa oa IC ke tlhophiso.Sena se tšoana le ho etsa qeto ea hore na u batla likamore tse kae le likamore tsa ho hlapa, hore na ke melao efe ea kaho eo u lokelang ho e latela, ebe u tsoela pele ka moralo ka mor'a hore u etse qeto ea mesebetsi eohle e le hore u se ke ua qeta nako e eketsehileng ho liphetoho tse latelang;Moralo oa IC o hloka ho feta ts'ebetsong e ts'oanang ho netefatsa hore chip e hlahisoang e ke ke ea ba le liphoso.

Mohato oa pele oa tlhaloso ke ho fumana sepheo sa IC, hore na tshebetso ke efe, le ho beha tataiso e akaretsang.Mohato o latelang ke ho bona hore na ke li-protocol tse lokelang ho finyelloa, tse kang IEEE 802.11 bakeng sa karete e se nang mohala, ho seng joalo chip e ke ke ea lumellana le lihlahisoa tse ling 'marakeng, e leng se etsang hore ho se ke ha khoneha ho hokahanya le lisebelisoa tse ling.Mohato oa ho qetela ke ho theha hore na IC e tla sebetsa joang, ho abela likarolo tse fapaneng mesebetsi e fapaneng le ho theha hore na likarolo tse fapaneng li tla hokahanngoa joang, kahoo ho phethela litlhaloso.

Kamora ho rala litlhaloso, ke nako ea ho rala lintlha tsa chip.Mohato ona o tšoana le setšoantšo sa pele sa moaho, moo kemiso ea kakaretso e rarolloang ho thusa litšoantšo tse latelang.Tabeng ea li-chips tsa IC, sena se etsoa ka ho sebelisa puo ea tlhaloso ea hardware (HDL) ho hlalosa potoloho.Li-HDL tse kang Verilog le VHDL hangata li sebelisoa ho hlahisa mesebetsi ea IC habonolo ka khoutu ea lenaneo.Ebe lenaneo le hlahlojoa ho nepahala le ho fetoloa ho fihlela le kopana le mosebetsi o lakatsehang.

Mekhahlelo ea li-photomasks, ho bokella chip

Pele ho tsohle, hona joale hoa tsebahala hore IC e hlahisa li-photomasks tse ngata, tse nang le mekhahlelo e fapaneng, e 'ngoe le e' ngoe e na le mosebetsi oa eona.Setšoantšo se ka tlase se bontša mohlala o bonolo oa photomask, o sebelisa CMOS, karolo ea motheo ka ho fetisisa potolohong e kopanetsoeng, e le mohlala.CMOS ke motsoako oa NMOS le PMOS, ho theha CMOS.

E 'ngoe le e 'ngoe ea mehato e hlalositsoeng mona e na le tsebo ea eona e khethehileng' me e ka rutoa e le thupelo e arohaneng.Ka mohlala, ho ngola puo ea tlhaloso ea hardware ha ho hloke feela ho tloaelana le puo ea lenaneo, empa hape ho hloka kutloisiso ea hore na li-circuits tsa logic li sebetsa joang, mokhoa oa ho fetola li-algorithms tse hlokahalang hore e be mananeo, le hore na software ea synthesis e fetola mananeo joang hore e be liheke tsa logic.

2.Sephaphatha ke eng?

Litabeng tsa semiconductor, ho lula ho buuoa ka masela ho latela boholo, joalo ka masela a 8" kapa a 12", empa ha e le hantle sephaphatha ke eng?Ke karolo efe ea 8" e buang ka eona? Hona ke mathata afe a ho etsa li-wafers tse kholo? Se latelang ke tataiso ea mohato ka mohato hore na sephaphatha ke eng, motheo oa bohlokoa ka ho fetisisa oa semiconductor.

Li-wafers ke motheo oa ho etsa mefuta eohle ea li-chips tsa khomphutha.Re ka bapisa tlhahiso ea li-chip le ho haha ​​​​ntlo e nang le li-block tsa Lego, re li bokella lera ka mor'a lesela ho etsa sebopeho se lakatsehang (ke hore li-chips tse fapaneng).Leha ho le joalo, ntle le motheo o motle, ntlo e hlahisoang e tla khopama 'me e se ke ea rata, kahoo ho etsa ntlo e phethahetseng, substrate e boreleli e hlokahala.Tabeng ea tlhahiso ea chip, substrate ena ke sephaphatha se tla hlalosoa ka mor'a moo.

Har'a lisebelisoa tse tiileng, ho na le mohaho o khethehileng oa kristale - monocrystalline.E na le thepa eo liathomo li hlophisoang ka mor'a tse ling haufi le tse ling, ho theha sebaka se bataletseng sa liathomo.Ka hona, li-wafers tsa monocrystalline li ka sebelisoa ho fihlela litlhoko tsena.Leha ho le joalo, ho na le mehato e 'meli e meholo ea ho hlahisa thepa e joalo, e leng ho hloekisa le ho hula ka kristale, ka mor'a moo boitsebiso bo ka phethoa.
