Kakaretso ea li-chips

(i) Chipi ke eng

Potoloho e kopaneng, e khutsufalitsoeng joalo ka IC;kapa microcircuit, microchip, chip ke mokhoa oa ho etsa lipotoloho tse nyenyane (haholo-holo lisebelisoa tsa semiconductor, empa hape le likarolo tse sa sebetseng, joalo-joalo) ka lisebelisoa tsa elektronike, 'me hangata li etsoa holim'a liphaphatha tsa semiconductor.

(ii) Mokhoa oa ho etsa chip

Ts'ebetso e felletseng ea ho etsa li-chip e kenyelletsa moralo oa li-chip, masela a liphaephe, ho etsa liphutheloana le tlhahlobo, eo ho eona mokhoa oa ho etsa li-wafer o rarahaneng haholo.

Ea pele ke moralo oa chip, ho latela litlhoko tsa moralo, "mohlala" o hlahisitsoeng, thepa e tala ea chip ke sephaphatha.

Sephaphatha se entsoe ka silicon, e hloekisitsoeng ho tloha lehlabatheng la quartz.Sefate ke ntho ea silicon e hloekisitsoeng (99.999%), ebe silicon e hloekileng e etsoa ka lithupa tsa silicon, e leng lisebelisoa tsa ho etsa li-semiconductors tsa quartz bakeng sa li-circuits tse kopantsoeng, tse arotsoeng ka li-wafers bakeng sa tlhahiso ea chip.Ha sephaphatha se le sesesane, se theola theko ea tlhahiso, empa ts'ebetso e hloka le ho feta.

Ho roala ka wafer

Ho roala ka Wafer ho hanyetsana le oxidation le ho hanyetsa mocheso 'me ke mofuta oa photoresist.

Kholiso ea Wafer Photolithography le etching

Mokhoa oa motheo oa mokhoa oa photolithography o bontšoa setšoantšong se ka tlase.Ntlha ea pele, lera la photoresist le sebelisoa holim'a sephaphatha (kapa substrate) le ho omisoa.Kamora ho omisa, sephaphatha se fetisetsoa mochining oa lithography.Leseli le fetisoa ka mask ho hlahisa mohlala oa mask holim'a photoresist holim'a bokaholimo, e leng se nolofalletsang ho pepeseha le ho susumetsa karabelo ea photochemical.Li-wafers tse pepesitsoeng li behoa lekhetlo la bobeli, tse tsejoang e le ho baka ka mor'a ho pepeseha, moo photochemical reaction e feletseng haholoanyane.Qetellong, moqapi o fafatsoa holim'a photoresist holim'a bokaholimo ho hlahisa mokhoa o pepeneneng.Ka mor'a tsoelo-pele, mohlala oa mask o sala ho photoresist.

Gluing, ho baka, le ntshetsopele tsohle li etsoa ho screed developer le pepeneneng e etsoa ka photolithograph.Moqapi oa screed le mochini oa lithography hangata o sebetsoa ka har'a marang-rang, 'me li-wafers li fetisetsoa lipakeng tsa likarolo le mochini o sebelisang roboto.Tsamaiso eohle ea ho pepeseha le nts'etsopele e koetsoe 'me li-wafers ha li pepesehe ka ho toba tikolohong e potolohileng ho fokotsa tšusumetso ea likarolo tse kotsi tikolohong ho photoresist le photochemical reaction.

Doping e nang le litšila

Ho kenya li-ion ka har'a sephaphatha ho hlahisa li-semiconductors tsa mofuta oa P le N.

Teko ea Wafer

Ka mor'a lits'ebetso tse ka holimo, lesela la dice le thehoa holim'a sephaphatha.Litšobotsi tsa motlakase tsa lefu le leng le le leng li hlahlojoa ho sebelisoa tlhahlobo ea pin.

Sephutheloana

Li-wafers tse entsoeng li tsitsitse, li tlanngoe ka lithakhisa, 'me li etsoa liphutheloana tse fapaneng ho latela litlhoko, ke ka lebaka leo "chip core" e tšoanang e ka kenngoa ka litsela tse fapaneng.Ka mohlala, DIP, QFP, PLCC, QFN, joalo-joalo.Mona e khethoa haholo-holo ke mekhoa ea ts'ebeliso ea mosebelisi, tikoloho ea ts'ebeliso, sebopeho sa mmaraka, le lintlha tse ling tse ka thoko.

Ho etsa liteko, ho paka

Kamora ts'ebetso e kaholimo, tlhahiso ea chip e felile.Mohato ona ke ho leka chip, ho tlosa lihlahisoa tse nang le bothata le ho li paka.

Kamano pakeng tsa li-wafers le chips

Chip e entsoe ka lisebelisoa tse fetang bonngoe tsa semiconductor.Li-semiconductors ka kakaretso ke diode, li-triodes, li-tubes tsa phello ea tšimo, li-resistors tse nyane tsa matla, li-inductors, li-capacitor, joalo-joalo.

Ke tšebeliso ea mekhoa ea botekgeniki ho fetola mahloriso a lielektrone tsa mahala khubung ea athomo selibeng se chitja ho fetola thepa ea 'mele ea nucleus ea athomo ho hlahisa tefiso e ntle kapa e mpe ea tse ngata (li-electrone) kapa tse seng kae (likoti) ho. etsa li-semiconductors tse fapaneng.

Silicon le germanium ke lisebelisoa tsa semiconductor tse sebelisoang ka tloaelo 'me thepa ea tsona le lisebelisoa li fumaneha habonolo ka bongata le ka theko e tlase bakeng sa tšebeliso ea mahlale ana.

Sephaphatha sa silicon se entsoe ka palo e kholo ea lisebelisoa tsa semiconductor.Mosebetsi oa semiconductor ke, ehlile, ho theha potoloho joalo ka ha ho hlokahala le ho ba teng ka har'a silicon wafer.
