Mhedziso yemachipisi

(i) Chii chinonzi chip

Dunhu rakabatanidzwa, rakapfupikiswa seIC;kana microcircuit, microchip, iyo chip inzira ye miniaturizing circuits (kunyanya semiconductor zvishandiso, asiwo passive components, etc.) mumagetsi, uye inowanzogadzirwa pamusoro pezvimedu zve semiconductor.

(ii) Chip kugadzira maitiro

Iyo yakazara chip yekugadzira maitiro inosanganisira chip dhizaini, kugadzirwa kwewafer, kugadzirwa kwepakeji, uye kuyedza, pakati peiyo nzira yekugadzira wafer inonyanya kuoma.

Chekutanga dhizaini yechip, zvinoenderana nezvinodiwa nedhizaini, iyo inogadzirwa "pattern", iyo mbishi yechip ndiyo wafer.

Iyo wafer inogadzirwa nesilicon, iyo inonatswa kubva kujecha requartz.Iyo wafer ndiyo silicon element yakacheneswa (99.999%), ipapo iyo silicon yakachena inogadzirwa kuva silicon tsvimbo, inova iyo yekugadzira quartz semiconductors yemasekete akabatanidzwa, ayo akachekwa kuita mawafer ekugadzira chip.Iyo yakatetepa iyo chitete, inoderedza mutengo wekugadzira, asi zvakanyanya kudiwa maitiro.

Wafer coating

Wafer coating inoshingirira kune oxidation uye tembiricha kuramba uye imhando yephotoresist.

Wafer photolithography kukura uye etching

Iyo yekutanga kuyerera kweiyo photolithography process inoratidzwa mudhayagiramu pazasi.Kutanga, chigadziko che photoresist chinoshandiswa pamusoro pechifukidziro (kana substrate) uye chakaomeswa.Mushure mekuoma, jira rinotamirwa kumushini we lithography.Chiedza chinopfuudzwa nemasiki kuti chigadzirise pateni pane mask pane photoresist pane wafer pamusoro, zvichiita kuratidzwa uye kukurudzira maitiro ephotochemical.Iwo mawafer akafumurwa anobva abikwa kechipiri, anozivikanwa se-post-exposure baking, uko iyo photochemical reaction inokwana.Chekupedzisira, mugadziri anopfapfaidzwa pane photoresist pane wafer pamusoro kuti igadzire iyo yakafumurwa pateni.Mushure mekusimudzira, iyo pateni pane mask inosara pane photoresist.

Gluing, kubika, uye kusimudzira zvese zvinoitwa mu screed developer uye kuratidzwa kunoitwa mufotolithograph.Iyo screed yekuvandudza uye muchina welithography inowanzo shandiswa mukati, newafers achitamiswa pakati pemayuniti nemuchina uchishandisa robhoti.Iyo yese yekuratidzwa uye yekusimudzira sisitimu yakavharwa uye mawafers haana kuratidzwa zvakananga kune yakatenderedza nharaunda kuti aderedze kukanganiswa kwezvinhu zvinokuvadza munharaunda pane photoresist uye photochemical reactions.

Doping netsvina

Kudyara maion muwafer kuti ibudise inoenderana P uye N-mhando semiconductors.

Wafer test

Mushure memaitiro ari pamusoro apa, lattice yedhayisi inoumbwa pawafa.Maitiro emagetsi ega ega efa anotariswa uchishandisa pini bvunzo.

Packaging

Iwo mawaferi akagadzirwa akagadziriswa, akasungwa kumapini, uye anogadzirwa mumapakeji akasiyana zvinoenderana nezvinodiwa, ndosaka iyo imwechete chip core inogona kuputirwa nenzira dzakasiyana.Somuenzaniso, DIP, QFP, PLCC, QFN, zvichingodaro.Pano zvinonyanya kutariswa nemaitiro ekushandisa emushandisi, nharaunda yekushandisa, chimiro chemusika, uye zvimwe zvinhu zvinotenderedza.

Kuedza, kurongedza

Mushure mekuita kwepamusoro, kugadzirwa kwechip kwapera.Iyi nhanho ndeyeyedza chip, kubvisa zvigadzirwa zvisina kukwana uye kurongedza.

Hukama pakati pewafers nemachipisi

Chipi chinoumbwa neinopfuura imwe semiconductor mudziyo.Semiconductors anowanzo ma diode, triodes, munda mhedzisiro machubhu, madiki emagetsi resistors, inductors, capacitors, zvichingodaro.

Iko kushandiswa kwehunyanzvi nzira kushandura kusangana kwemaerekitironi akasununguka munyukiresi yeatomu mutsime rakatenderera kushandura chimiro chechimiro cheatomu nucleus kuti ibudise chaji yakanaka kana yakaipa yeakawanda (maerekitironi) kana mashoma (maburi) kuti gadzira akasiyana semiconductors.

Silicon uye germanium zvinowanzoshandiswa semiconductor zvinhu uye zvivakwa zvavo uye zvinhu zviri nyore kuwanikwa muhuwandu uye nemutengo wakaderera wekushandisa mune aya matekinoroji.

Siricon wafer inoumbwa nenhamba huru yemidziyo yesemiconductor.Basa re semiconductor ndere, hongu, kugadzira dunhu sezvinodiwa uye kuvapo mune silicon wafer.
