Ukukhiqizwa kwe-semiconductor yesimanje kusebenza ngezinga lobunzima okunzima ukuligcizelela. I-logic chip ehamba phambili iqukethe ama-transistors anobude besango obulinganiswa ngama-nanometer ambalwa - amancane kunobubanzi bomucu we-DNA. Ukuphrinta lezi zici ku-silicon wafer kudinga ukunemba kokubeka okwenza ngisho nobunjiniyela bemishini obunembile kakhulu bezikhathi zezimboni zangaphambilini bubukeke buqinile uma kuqhathaniswa. Kodwa esisekelweni sale nqubo ye-nanoscale - ngokuvamile ngokoqobo - kuhlezi ibhlogo ledwala elicwengekile eliklanywe kahle.
Izingxenye zesakhiwo se-granite zitholakala kakhulu emishinini emikhulu ye-semiconductor, futhi ukuqonda ukuthi kungani kudinga ukubheka ubunjiniyela obuphelele bezinga lesistimu yale mishini: ukuthi yimaphi amaphutha okudingeka alawulwe, ukuthi asakazeka kanjani ohlelweni, nokuthi yiziphi izakhiwo zezinto ezenza i-granite ifaneleke kahle kakhulu indima eyidlalayo.
Isabelomali Sephutha Lemishini Ye-Semiconductor: Ukuqonda I-Stack
Zonke izinhlelo zokubeka ngokunemba — kanye nemishini yokucubungula i-semiconductor empeleni iqoqo lezinhlelo zokubeka ngokunemba kakhulu — zisebenza ngokumelene nalokho onjiniyela abakubiza ngokuthi isabelomali samaphutha. Iphutha eliphelele lokubeka elivumelekile lisatshalaliswa kuzo zonke izinsiza zamaphutha ohlelweni: ukulungiswa kwe-encoder, ukunemba kwamabhere, ukukhukhuleka kokushisa, ukudlidliza, ukungalungi kwe-actuator, kanye nokuguqulwa kwesakhiwo, phakathi kokunye.
Ku-scanner ye-photolithography noma uhlelo lwesinyathelo-nokuskena olusetshenziselwa ukukhiqizwa kwe-IC, iphutha eliphelele lokumboza (ukunemba lapho ungqimba olulodwa oluphrintiwe luhambisana nolwangaphambilini) kumele lilawulwe libe yingxenyana yobukhulu besici obuncane obuphrintiwe. Kuma-node enqubo angu-7nm, izidingo zokumboza zingaba ngaphansi kuka-2nm. Umnikelo wesisekelo sesakhiwo kulesi sabelomali sephutha - ngokukhukhuleka kokushisa, ukuhlanganiswa kokudlidliza, noma ukungazinzi kwesikhathi eside - kumele kugcinwe engxenyeni encane yalesi samba.
Lokhu akuyona isithiyo esingahlangatshezwa ngokusebenzisa i-algorithm ehlukile yokulawula noma inzwa esheshayo. Kudinga ukuthi izinto zokwakha zizinzile ngokwemvelo. Awukwazi ukulungisa impendulo-ukulungisa ukuzulazula ongakwazi ukukulinganisa, futhi awukwazi ukukhokhela ngokugcwele amaphutha ayenzeka kumaza noma ezikalini zobude ngaphansi kwesinqumo senzwa yakho. Yingakho ukukhetha izinto eziyisisekelo kubalulekile: kunquma phansi okuyisisekelo ngaphansi kwalokho ukulawula okusebenzayo okungenakukusiza.
Ukuphathwa Kokushisa: Inselele Ephakathi
Kuzo zonke izidingo zokuzinza ezibekwa ezingxenyeni zesakhiwo emishinini ye-semiconductor, ukuphathwa kokushisa ngokuvamile kuyinto edinga kakhulu. Izindawo zokucubungula ama-semiconductor zilawulwa ngokuqapha okukhulu - amakamelo okuhlanza e-lithography ngokuvamile agcinwa ku-20°C ± 0.01°C noma aqine kakhulu endaweni yokuchayeka. Kodwa ngisho nangaleli zinga lokulawula kwemvelo, ama-gradient okushisa kanye nokushintshashintsha kwesikhashana kubeka imingcele ekwakhiweni kwemishini.
Cabanga ngesakhiwo se-granite gantry esisekela isigaba se-wafer ohlelweni lwe-photolithography. Uma lesi sakhiwo sibhekana nokushisa okungu-0.01°C kusukela kolunye uhlangothi kuya kolunye — kakade isimo esilawulwa kahle kakhulu — futhi singamamitha angu-1 ubude ne-CTE engu-7 × 10⁻⁶/°C, ukwanda komehluko okubangelwayo kungaba cishe ama-picometer angu-70. Uma ubheka kuqala, lokhu kubonakala kuncane kakhulu. Kodwa ngokomongo wencazelo ye-overlay engu-2nm, lo mnikelo owodwa wokushisa usuvele udla u-3.5% wesabelomali samaphutha esiphelele. Yonke eminye imithombo yokushisa — ukushisa kwemoto, ukungqubuzana kokuthwala, amandla okusheshisa isigaba — incintisana nesabelomali esisele.
Yingakho i-coefficient yokushisa yokwandisa ingeyona nje into ecacisiwe ye-granite - kuyinqubo yokukhetha eyinhloko.
