Ezinhlelweni zobunjiniyela ezinembile kakhulu, ukukhethwa kwezinto akusona isinqumo sezindleko kodwa kuyipharamitha echaza ukusebenza. Izisekelo zomshini, amapulatifomu e-metrology, izigaba ze-semiconductor, kanye nezakhiwo zokuqondanisa kwe-optical zisebenza ngama-tolerances asukela kuma-micrometer kuya kuma-nanometer. Kulezi zikali, ukuzinza kokushisa, ukufana kwesakhiwo se-microstructure, ukudambisa ukudlidliza, kanye nokuzinza kobukhulu besikhathi eside kuba yizithiyo ezibalulekile zobunjiniyela.

Kusetshenziswa izinhlobo ezimbili zezinto ezivelele kulesi sigaba: i-granite yemvelo kanye ne-ceramics yobunjiniyela obuthuthukisiwe (ngokuvamile izinto ezisekelwe ku-alumina noma i-silicon carbide). Nakuba zombili zisetshenziswa kuizinhlelo zokunemba, imvelaphi yazo engokwenyama, izakhiwo ezincane, kanye nezici zokusebenza kuhluke kakhulu.

Izinhlelo zezimboni ezisebenza kahle kakhulu ezithuthukiswe abakhiqizi abanjengo-ZHHIMG zivame ukuhlola lezi zinto hhayi njengezithatha indawo, kodwa njengezixazululo ezihlukile ngokusebenza kwezakhiwo zesistimu ezahlukene.

1. Izisekelo Zesayensi Yezinto Ezibonakalayo

1.1 I-Granite: Izinto Ezihlanganisiwe Zemvelo Ezine-Polycrystalline

8. Indima ohlelweni lwe-Ecosystem Yemboni Enembile Kakhulu

Ezindaweni zokukhiqiza ze-semiconductor kanye nezithuthukisiwe, zombili izinto zisebenza izindima ezihambisanayo kunezokuncintisana.

Abakhiqizi abanjengoZHHIMG bahlanganisa zombili izinto zokwakha ngokunemba okunezingqimba eziningi lapho:

• I-Granite ichaza ukuzinza kwesakhiwo somhlaba wonke
• I-Ceramics ichaza ukunemba kokusebenza kwendawo

Le ndlela yokuklama ezingeni lesistimu ibalulekile ekufezeni ukusebenza kwekilasi le-nanometer.

Isiphetho

I-granite kanye ne-ceramics yobunjiniyela zimelela amafilosofi amabili ahlukene ngokuyisisekelo kubunjiniyela bokunemba: enye isekelwe ekwakhekeni kwekristalu yemvelo ye-stochastic, enye ekwakhiweni kwesakhiwo esincane esilawulwayo.

I-granite ihamba phambili ekuncipheni, ekuzinzeni, nasekuqineni kwesakhiwo esikhulu, kuyilapho izinto zobumba zibusa ekuqineni, ekuqhutshweni kokushisa, kanye nasekulawuleni ukunemba kwezinga elincane. Azikho izinto ezingcono kakhulu emhlabeni wonke; kunalokho, ngayinye ichaza ukusebenza okuhle ngaphakathi kwendawo yayo yokusebenza.

Ezinhlelweni ezithuthukisiwe kakhulu, ikusasa akusikho ukufaka esikhundleni sezinto ezibonakalayo kodwa ukuhlanganiswa kwezinto ezibonakalayo, lapho i-granite kanye ne-ceramics kuhlangana khona njengezendlalelo ezisebenzayo ezihambisanayo kumapulatifomu ayinkimbinkimbi okukala kanye nokukhiqiza.
