Fraunhofer IISB (Ikigo cy’Ubuhanga n’Ikoranabuhanga ry’Ibikoresho) cyo muri Erlangen hamwe n’ikigo gikora ikoranabuhanga rya microwave na radio frequency PVA TePla AG cyo muri Wettenberg barimo guhuriza hamwe ubumenyi bwabo muri Joint Laboratory mu gukora kristu za aluminiyumu nitride (AlN).
Nk’uko byabanje kuba i Burayi, ubu bufatanye butuma habaho umusaruro mu nganda muto wa monocrystalline AlN substrates zifite umurambararo wa santimetero 2 mu rwego rw’ubushakashatsi n’iterambere. Ibi binoza cyane uburyo AlN substrates ziboneka mu Burayi, ibyo bigatuma iterambere ry’ibikoresho na sisitemu bishingiye kuri AlN rirushaho kwihutishwa no gukoreshwa mu nganda.
Nitride ya aluminiyumu ni kimwe mu bikoresho bitanga icyizere ku gisekuru gitaha cy’ibikoresho by’ikoranabuhanga bigezweho. Nk’igikoresho cy’ikoranabuhanga cya ultrawide-bandgap (UWBG), AlN ifunguye amahirwe mashya mu by’ikoranabuhanga rya fotoniki, ibikoresho by’ikoranabuhanga bikoresha ingufu, ibikoresho by’ikoranabuhanga bikoresha frequency nyinshi, n’ibikoresho by’ikoranabuhanga bikoresha ikoranabuhanga mu bihe bikomeye. Kugeza ubu, ibura ry’ibikoresho bya AlN byiza, binini kandi bihendutse byadindije iterambere rya sisitemu z’ikoranabuhanga zikoresha AlN.
“Hamwe na Joint Lab, turimo gushyiraho urufatiro rwo kwemeza ko hari ibikoresho bya AlN bituruka i Burayi byizewe, bityo tugafungura amahirwe mashya ku gisekuru gitaha cy’ibikoresho bya AlN bikora neza cyane,” ibi ni ibyatangajwe na Dr Sven Besendörfer, umuyobozi w’itsinda rishinzwe ibikoresho bya nitride akaba n’ushinzwe iterambere ry’ibikoresho bya AlN muri Fraunhofer IISB. “Dufatanyije na PVA TePla, turimo gutanga ubumenyi bwacu mu iterambere ry’inganda, bityo tugashyiraho ibisabwa kugira ngo ikoreshwa ryabyo rishyirwe mu bikorwa bifatika.”
Ikoranabuhanga ry’ibikoresho ryizewe rihuye n’ubumenyi bwihariye mu mikorere
Muri laboratwari ihuriweho, Fraunhofer IISB ikoresha ikoranabuhanga ryayo rya PVT (uburyo bwo gutwara umwuka ushyushye) kugira ngo ikore kristu za AlN za santimetero 2. Muri ubu buryo, ifu ya AlN ishyirwa mu cyuma gishyushya mu bushyuhe buri hejuru ya dogere selisiyusi 2000 hanyuma igashyirwa ku kristu y'imbuto. PVA TePla itanga sisitemu za PVT kuri iyi ntego, zisanzwe zikoreshwa ku isi yose mu kristu za silikoni karubide (SiC) za santimetero 2 kandi ubu zahinduwe by'umwihariko kugira ngo kristu za AlN za santimetero 2 zikure.
Bitewe n'ubuhanga mu mikorere bwatanzwe na Fraunhofer IISB, itsinda rya PVA TePla ryashoboye vuba gukora kristu za AlN zifite ubuziranenge nk'ubwo mu nganda zaryo. Ikigo cya Joint Laboratory cyibanda ku musaruro muto uhoraho wa kristu za AlN za santimetero 2. Umusaruro ubu uri kwiyongera buhoro buhoro kugira ngo wongere uburyo bwo kunoza uburyo bwo guhindagurika, kongera umusaruro, umusaruro n'imiterere y'ikiguzi.
“Dukoresheje aluminiyumu nitride, turimo gushyiraho imbaraga mu iterambere ry’ikoranabuhanga rikurikira SiC,” Dr Jan Pfeiffer, visi perezida w’ubushakashatsi n’iterambere muri PVA TePla, agira ati: “Binyuze muri Joint Laboratory, dushobora guhuza ubuhanga bwacu mu bikoresho n’ubumenyi bw’imikorere bwa Fraunhofer IISB, bigatuma dutanga ibisubizo bishingiye ku isoko ku bakiriya bacu bo ku isi mu ntangiriro,” yongeraho ati: “Intego yacu rusange ni uguteza imbere iterambere ry’isoko mu rwego rwa AlN binyuze mu buryo bukwiye no gushyigikira amasosiyete ashaka kwinjira muri uru rwego nk’abafatanyabikorwa mu ikoranabuhanga n’ibikoresho bikwiye n’ubuhanga mu mikorere ijyanye nabyo.”
Gushimangira ubwigenge bw'ikoranabuhanga mu Burayi binyuze mu kwagura inganda
Uduce twa AlN dukorerwa muri Joint Laboratwari twongera gutunganywa muri Fraunhofer IISB mu duce twa AlN twiteguye gukoreshwa, kandi binyuze mu kigo cy’ubushakashatsi n’iterambere ry’ibicuruzwa cya Erlangen LZE GmbH, by’umwihariko twimurirwa mu iterambere ry’inganda no kwagura ibikorwa. Umuyobozi mukuru wa LZE, Dr Christian Forster, agira ati: “Kugira ngo habeho ubusugire bw’ibikoresho bya semiconductor mu Burayi, ni ngombwa ko ibikoresho bishya by’ingenzi bitaba gusa bitera imbere, ahubwo binashyirwa mu bikorwa byihuse mu nganda no mu kurema agaciro gashoboka.” “Kubera isoko ryayo ry’ikoranabuhanga rigezweho, LZE GmbH iha amasosiyete n’ibigo by’ubushakashatsi uburenganzira bwihariye ku isi ku duce twa AlN. Muri ubu buryo, dufasha kwemeza ko ibikorwa byiza ku masoko y’inganda menshi bigezwa ku isoko vuba.”
