Isitoko esisha sangempela soqobo se-IC I-Electronic Components I-Ic Chip Support BOM Service TPS62130AQRGTRQ1

1.

Uma sesazi ukuthi i-IC yakhiwa kanjani, sekuyisikhathi sokuchaza ukuthi yenziwa kanjani.Ukwenza umdwebo onemininingwane nge-spray can of paint, sidinga ukusika imaski yomdwebo bese siyibeka ephepheni.Bese sifafaza upende ngokulinganayo ephepheni bese sisusa imaski lapho upende sewomile.Lokhu kuphindaphindwa kaningi ukuze kwakhiwe iphethini ehlanzekile neyinkimbinkimbi.Ngenziwe ngendlela efanayo, ngokupakisha izendlalelo phezu kwesinye ngenqubo yokufihla ubuso.

Ukukhiqizwa kwama-ICs kungahlukaniswa ngalezi zinyathelo ezi-4 ezilula.Nakuba izinyathelo zangempela zokukhiqiza zingahluka futhi izinto ezisetshenziswayo zingahluka, isimiso esijwayelekile siyefana.Le nqubo ihluke kancane ekudwebeni, ngokuthi ama-IC akhiqizwa ngopende abese egqunywa, kuyilapho upende uqala ukugqunywa bese uyapendwa.Inqubo ngayinye ichazwe ngezansi.

I-Metal sputtering: Izinto zensimbi ezizosetshenziswa zifafazwa ngokulinganayo ku-wafer ukwenza ifilimu elincanyana.

Uhlelo lokusebenza lwe-Photoresist: Impahla ye-photoresist ifakwa kuqala ku-wafer, futhi nge-photomask (isimiso se-photoresist sizochazwa ngokuzayo), i-beam yokukhanya ishaywa engxenyeni engadingeki ukucekela phansi isakhiwo se-photoresist material.Izinto ezilimele zibe sezikhukhulwa ngamakhemikhali.

I-Etching: Iwafa ye-silicon, engavikelwe yi-photoresist, iqoshwe nge-ion beam.

Ukususwa kwe-Photoresist: I-photoresist esele ichithwa kusetshenziswa isixazululo sokususa i-photoresist, ngaleyo ndlela kuphothulwe inqubo.

Umphumela wokugcina ungama-chips ambalwa e-6IC ku-wafer eyodwa, abese esikwa bese ethunyelwa embonini yokupakisha ukuze afakwe.

2.Iyini inqubo ye-nanometer?

AbakwaSamsung kanye ne-TSMC balwa nayo ngenqubo ye-semiconductor ethuthukisiwe, ngayinye izama ukuthola isiqalo endaweni yokuvikela ama-oda, futhi sekucishe kwaba impi phakathi kuka-14nm no-16nm.Futhi yiziphi izinzuzo nezinkinga ezizolethwa inqubo encishisiwe?Ngezansi sizochaza kafushane inqubo ye-nanometer.

Incane kangakanani i-nanometer?

Ngaphambi kokuba siqale, kubalulekile ukuqonda ukuthi ama-nanometers asho ukuthini.Ngokwezibalo, i-nanometer iyimitha elingu-0.000000001, kodwa lesi isibonelo esibi kakhulu - phela singabona oziro abambalwa ngemva kwephoyinti ledesimali kodwa asinawo umqondo wangempela walokho abayikho.Uma siqhathanisa lokhu nobukhulu bozipho lomunwe, kungase kubonakale kakhudlwana.

Uma sisebenzisa irula ukukala ukujiya kwesipikili, singabona ukuthi ukujiya kwesipikili kungamamitha ayi-0.0001 (0.1 mm), okusho ukuthi uma sizama ukusika uhlangothi lwesipikili lube imigqa eyi-100,000, umugqa ngamunye. ilingana ne-nanometer engu-1.

Uma sesazi ukuthi i-nanometer incane kangakanani, sidinga ukuqonda injongo yokunciphisa inqubo.Inhloso eyinhloko yokunciphisa ikristalu ukufaka amakristalu engeziwe ku-chip encane ukuze i-chip ingabi nkulu ngenxa yentuthuko yezobuchwepheshe.Ekugcineni, usayizi oncishisiwe we-chip uzokwenza kube lula ukungena kumadivayisi eselula futhi ihlangabezane nesidingo sesikhathi esizayo sobuncane.

Uma sithatha i-14nm njengesibonelo, inqubo ibhekisela kusayizi wentambo omncane ongakhona ongu-14nm ku-chip.
