Kungani Abakhiqizi Bemishini Ye-Semiconductor Bechaza Izisekelo Ze-Granite Zemvelo - Izizathu Ezi-5 Ezibalulekile

Ezweni elibaluleke kakhulu lokwenziwa kwe-semiconductor, lapho ubukhulu besici bulinganiswa ngama-nanometer, isisekelo somshini sibaluleke kakhulu njenge-optics noma uhlelo lwe-vacuum. Kungakhathaliseki ukuthi umshini wokuhlola i-wafer noma uhlelo lwe-lithography olujulile lwe-ultraviolet (DUV), ama-OEM omhlaba wonke ahlala echaza i-granite emnyama yemvelo ngezisekelo zawo zesakhiwo.

Kodwa kungani itshe lemvelo liyindinganiso yegolide embonini echazwa ngezinto zokwenziwa ezisezingeni eliphezulu? Nazi izizathu ezinhlanu zobuchwepheshe zokuthi kungani i-granite yemvelo iyindlela engaxoxiswana ngayo yemishini ye-semiconductor.

1. Ukuzinza Okuphezulu Kokushisa ku-Fab

Indawo ye-semiconductor “Front-End” idinga ukuhambisana okuphelele kobukhulu. Ngisho nengxenye encane yezinga lokushintshashintsha kwezinga lokushisa ingabangela ukuthi izakhiwo zensimbi zande, okuholela emaphutheni okumboza noma “ukufiphala” ku-lithography.

I-granite yemvelo ine-Coefficient of Thermal Expansion (CTE) ephansi kakhulu. Uma kuqhathaniswaisisekelo se-graniteNgomshini wokuhlola i-wafer esikhundleni sensimbi noma i-aluminium, i-granite ihlala "iqandisiwe" ngobukhulu naphezu kokushintsha okuncane kwemvelo. Lokhu kushisa okungenakuqhathaniswa kuqinisekisa ukuthi indlela ye-optical ihlala iqondaniswe kusukela ku-wafer yokuqala ye-shift kuya kokugcina.

2. Ukudambisa Ukudlidliza Okumangalisayo Kokunemba Kwe-Nanometer

Imishini ye-lithography kanye namathuluzi okukala amazinga aphezulu esisindo azwela kakhulu “kumsindo”—ukudlidliza okuvela phansi efektri, kumafeni okupholisa, noma kubaphathi be-wafer berobhothi.

Nakuba izinsimbi zivame “ukukhala” (zidlidliza isikhathi eside ngemva kokushayisana), i-granite yemvelo inamandla aphezulu okudambisa ngaphakathi. Imunca futhi ichithe amandla e-kinetic ngokushesha. Le granite yokudambisa ukudlidliza yemishini ye-lithography ivumela umshini ukuthi uhlale ngokushesha ngemva kokunyakaza kwesiteji ngesivinini esikhulu, okwandisa kakhulu ukudlula kwethuluzi “Amayunithi Ngehora” (UPH).

3. Akuyona i-Magnetic futhi ayihambisani nogesi

Izinqubo ze-semiconductor zivame ukuhilela imisebe yama-electron ebucayi (i-E-beam) noma ama-magnetic linear motors anemba kakhulu. Isisekelo sensimbi singaphazamisa la masimu kazibuthe noma sidale imisinga ye-eddy ephazamisa ukunemba kwenzwa.

Njengesivikelo semvelo, i-granite inikeza ipulatifomu ye-metrology engeyona i-magnetic yamakamelo okuhlanza. Ayiphazamisi indawo ye-electromagnetic yaleli thuluzi, okuvumela idatha emsulwa, engonakaliswanga ngesikhathi sokumapha kwe-wafer topography noma ukuhlolwa kwesici.

4. Ukumelana Nokugqwala Nokuhambisana Negumbi Lokuhlanza

Egumbini lokuhlanza (Isigaba 1 noma Isigaba 10), ukuphuma kwegesi kanye nokukhiqizwa kwezinhlayiya kuyizitha zokukhiqiza. Ngokungafani nensimbi ephonswe noma insimbi, i-granite yemvelo ayigqwali, ayixubi, noma ayidingi upende wamakhemikhali kanye nopende olungaqhekeka noma luphume igesi ngokuhamba kwesikhathi.

I-granite ayisebenzi ngamakhemikhali. Ngisho noma itholakala ezintweni zokuhlanza ezikhethekile ezisetshenziswa kumshini wokuthunga, igcina ubuso bayo buqinile. Isakhiwo sayo esinobukhulu obuphezulu (cishe 3100kg/m³) siqinisekisa ukuthi ihlala “ingathathi hlangothi” kuyo yonke inkathi yokuphila kwemishini.

5. Ukufinyelela "Ukuthamba Kweqiniso" Ngokubamba Ngesandla

Embonini ye-semiconductor, “isicaba” asisicaba ngokwanele. Izingxenye zivame ukudinga ukunemba kwezinga le-nano okuyinto imishini ye-CNC engenakukwazi ukuyifinyelela.

I-granite yemvelo ivumela ukugoqa ngesandla, inqubo yokulungisa ngesandla lapho ochwepheshe abangochwepheshe befinyelela khona ukubekezelelana kobuthambathi okuqinile njengo-±0.001mm. Leli zinga lokunemba libalulekile ezigabeni zokuthwala umoya ezisetshenziswa kuma-wafer scanner anamuhla, lapho igebe lomoya phakathi kwesiteji nesisekelo kumele lihlale lifana ngokuphelele kulo lonke ibanga lokuhamba.

Inzuzo ye-ZHHIMG: Ukunemba kwe-Nano-Age

Kwa-UNPARALLELED (ZHHIMG), sikuqonda kangcono ukuzinza kokushisa kwe-granite ezintweni ze-semiconductor fabs. Sihlinzeka ngezingxenye ze-granite ezenziwe ngokwezifiso kubakhiqizi bamathuluzi e-semiconductor abahamba phambili emhlabeni, abangochwepheshe ku:

• Izisekelo ezihambisana ne-vacuum ezinkulu kakhulu.

• Imisebe eqondile yezinhlelo ze-gantry ezisheshayo.

• Izifaki ezihlanganisiwe zokufaka injini eqondile.

I-granite yethu emnyama enobukhulu obuphezulu itholakala futhi icutshungulwe ukuze ihlangabezane nezimfuneko ezifunwa kakhulu ze-semiconductor roadmap yomhlaba wonke.
