Iqembu lomcwaningi u-Yang Liang e-Suzhou Institute for Advanced Study eNyuvesi Yesayensi Nobuchwepheshe yaseChina lenze indlela entsha yokukhiqiza i-metal oxide semiconductor laser micro-nano, ebone ukuphrinta ngelaser kwezakhiwo ze-semiconductor ze-ZnO ngokunemba kwe-submicron, futhi kuhlangene. nge-laser yensimbi yokuphrinta, okokuqala ngqa iqinisekise ukubhalwa okuqondile kwe-laser okudidiyelwe kwezingxenye ezincane zama-microelectronic namasekethe afana nama-diode, ama-triode, ama-memristors namasekhethi wokubethela, ngaleyo ndlela andisa izimo zokusetshenziswa kokucubungula kwe-laser micro-nano emkhakheni we-microelectronics, i-electronics flexible, izinzwa ezithuthukisiwe, i-Intelligent MEMS kanye neminye imikhakha inamathuba okufaka isicelo abalulekile.Imiphumela yocwaningo isanda kushicilelwa ku-"Nature Communications" ngaphansi kwesihloko esithi "Laser Printed Microelectronics".
Imishini kagesi ephrintiwe ubuchwepheshe obusafufusa obusebenzisa izindlela zokuphrinta ukwenza imikhiqizo kagesi.Ihlangabezana nezici zokuguquguquka nokwenza kube ngokwakho isizukulwane esisha semikhiqizo kagesi, futhi izoletha uguquko olusha lwezobuchwepheshe embonini ye-microelectronics.Eminyakeni engu-20 edlule, ukuphrinta kwe-inkjet, ukudluliswa kwe-laser-induced transfer (LIFT), noma amanye amasu okuphrinta enze igxathu elikhulu ukuze kunikwe amandla ukwakhiwa kwamadivayisi asebenzayo e-organic kanye ne-inorganic microelectronic ngaphandle kwesidingo sendawo yegumbi elihlanzekile.Kodwa-ke, usayizi wesici ojwayelekile wezindlela zokuphrinta ezingenhla uvamise ukuba ngohlelo lwamashumi ama-microns, futhi ngokuvamile udinga inqubo yokucubungula ngemva kokushisa okuphezulu, noma uncike kwinhlanganisela yezinqubo eziningi ukuze kufezwe ukucutshungulwa kwamadivayisi asebenzayo.Ubuchwepheshe bokucutshungulwa kwe-laser micro-nano busebenzisa ukusebenzisana okungaqondile phakathi kwama-laser pulses nezinto zokwakha, futhi bungafinyelela izakhiwo eziyinkimbinkimbi zokusebenza kanye nokukhiqizwa okungeziwe kwamadivayisi okunzima ukukufeza ngezindlela zendabuko ngokunemba okungu-<100 nm.Kodwa-ke, iningi lezakhiwo zamanje ezenziwe nge-laser micro-nano-fabricated ziyizinto ze-polymer eyodwa noma izinto zensimbi.Ukuntuleka kwezindlela zokubhala eziqondile ze-laser zezinto zokwakha ze-semiconductor nakho kwenza kube nzima ukwandisa ukusetshenziswa kobuchwepheshe bokucubungula i-laser micro-nano emkhakheni wemishini ye-microelectronic.
Kule thesis, umcwaningi u-Yang Liang, ngokubambisana nabacwaningi baseJalimane nase-Australia, bathuthukise ngokusha ukuphrinta kwe-laser njengobuchwepheshe bokuphrinta bemishini kagesi esebenzayo, beqaphela i-semiconductor (ZnO) kanye nomqhubi (Ukuphrinta kwe-laser eyinhlanganisela yezinto ezihlukahlukene ezifana ne-Pt ne-Ag) (Umfanekiso 1), futhi awudingi noma yiziphi izinyathelo zenqubo yangemva kokucubungula yezinga eliphezulu lokushisa, futhi usayizi omncane wesici ungu-<1 µm.Lokhu kuphumelela kwenza kube nokwenzeka ukwenza ngendlela oyifisayo ukuklama nokuphrinta kwamakhondatha, ama-semiconductors, ngisho nokuhlelwa kwezinto zokuvikela ukushisa ngokuvumelana nemisebenzi yamadivaysi e-microelectronic, okuthuthukisa kakhulu ukunemba, ukuguquguquka, kanye nokulawulwa kwezinto zokunyathelisa zama-microelectronic.Ngalesi sisekelo, ithimba locwaningo libone ngempumelelo ukubhalwa okuqondile kwe-laser okudidiyelwe kwama-diode, ama-memristors kanye namasekhethi wokubethela angakwazi ukukhiqiza kabusha (Umfanekiso 2).Lobu buchwepheshe buhambisana nokuphrinta kwe-inkjet yendabuko kanye nobunye ubuchwepheshe, futhi kulindeleke ukuthi inwetshelwe ekunyatheliseni izinto ezihlukahlukene ze-P-type kanye ne-N-type semiconductor metal oxide, ukuhlinzeka ngendlela entsha ehlelekile yokucubungula izinto eziyinkimbinkimbi, ezinkulu, amadivaysi e-microelectronic asebenzayo anezinhlangothi ezintathu.
