I-Aluminium Nitride, Enye Yezinto Zobumba Ezithembisa Kakhulu

2022-10-25

Njengoba izifunda ezihlanganisiwe seziphenduke imboni yezwe enamasu, izinto eziningi ze-semiconductor ziye zacwaningwa futhi zathuthukiswa, futhi i-Aluminium Nitride ngokungangabazeki ingenye yezinto ezithembisa kakhulu ze-semiconductor.

I-Aluminium Nitride Performance Characters

I-Aluminium Nitride (i-AlN) inezici zamandla aphezulu, ukumelana nevolumu ephezulu, amandla okushisa aphezulu, i-coefficient yokunwetshwa kwe-thermal, ukufanisa okuhle ne-silicon, njll. Ayisetshenziswa nje kuphela njenge-sintering aid noma isigaba sokuqinisa i-ceramics yesakhiwo kodwa futhi iyasetshenziswa. emkhakheni we-ceramic electronic substrates kanye nezinto zokupakisha, eziye zanda eminyakeni yamuva nje, futhi ukusebenza kwayo kudlula kude lokho kwe-Alumina. Izitsha zobumba ze-Aluminium Nitride zinokusebenza okuhle kakhulu sekukonke, zilungele ama-semiconductor substrates nezinto zokupakisha zesakhiwo, futhi zinamandla amakhulu okusebenza embonini yezogesi.

Ukusetshenziswa kwe-Aluminium Nitride

1. Izinhlelo zokusebenza zedivayisi ye-Piezoelectric

I-Aluminium Nitride inokumelana okuphezulu, ukuqhutshwa kokushisa okuphezulu, kanye ne-coefficient ephansi yokwandisa okufana ne-silicon, okuyinto efanelekile yokushisa okuphezulu kanye namadivaysi e-elekthronikhi anamandla amakhulu.

2. Izinto ze-elekthronikhi zokupakisha ze-substrate

I-Beryllium Oxide, i-Alumina, i-Silicon Nitride, ne-Aluminium Nitride ngezinye zezinto ezisetshenziswa kakhulu kuma-substrates e-ceramic.

Phakathi kwezinto ezikhona ze-ceramic ezingasetshenziswa njengezinto ze-substrate, ama-ceramics e-Silicon Nitride anamandla aphakeme kakhulu aguquguqukayo, ukumelana nokugqoka okuhle, kanye nezakhiwo eziphelele zemishini yezinto ze-ceramic, kuyilapho i-coefficient yazo yokwandisa okushisayo incane kakhulu. Ama-ceramics e-Aluminium Nitride ane-conductivity ephezulu ye-thermal, ukumelana nokushaqeka okuhle kokushisa, futhi asenezici ezinhle zemishini emazingeni okushisa aphezulu. Kungashiwo ukuthi, kusukela ekubukeni kokusebenza, i-Aluminium Nitride ne-Silicon Nitride okwamanje ifaneleka kakhulu ukusetshenziswa njengezinto ze-electronic packaging substrate, kodwa futhi zinenkinga evamile: intengo yabo iphezulu.

3. Ukusetshenziswa kwezinto ezikhipha ukukhanya

Mayelana nokusebenza kahle kokuguqulwa kwe-photoelectric, i-aluminium nitride (i-AlN) inebhendi ye-semiconductor yebhande eqondile yobubanzi obungu-6.2 eV, ephakeme kunesemiconductor ye-bandgap engaqondile. I-AlN, njengento ebalulekile ekhipha ukukhanya okuluhlaza okwesibhakabhaka ne-ultraviolet, isetshenziswa kuma-diode e-ultraviolet kanye ne-ultraviolet ejulile ekhipha ukukhanya, ama-ultraviolet laser diode, imitshina ye-ultraviolet, njll. isixazululo, futhi igebe lebhande le-alloy yayo ye-ternary noma ye-quaternary ingalungiswa ngokuqhubekayo kusukela ebhendini ebonakalayo kuya ebhendini ejulile ye-ultraviolet, okuyenza ibe yinto ebalulekile esebenza kahle kakhulu ekhipha ukukhanya.

4. Ukufakwa kwe-substrate materials

I-AlN crystal iyingxenye ekahle yezinto ze-epitaxial ze-GaN, i-AlGaN, ne-AlN. Uma kuqhathaniswa nama-sapphire noma ama-SiC substrates, i-AlN ne-GaN inokufanisa okungcono kwe-thermal nokuhambisana kwamakhemikhali, futhi ingcindezi phakathi kwe-substrate ne-epitaxial layer incane. Ngakho-ke, amakristalu e-AlN njengama-substrates e-GaN epitaxial anganciphisa kakhulu ukuminyana kwesici kudivayisi futhi athuthukise ukusebenza kwawo, okunethuba elihle kakhulu lokusetshenziswa ekulungiseleleni izinga lokushisa eliphezulu, imvamisa ephezulu, kanye namadivayisi kagesi anamandla amakhulu. Ngaphezu kwalokho, ukusebenzisa amakristalu e-AlN njenge-AlGaN epitaxial material substrate enezingxenye eziphezulu ze-aluminium (Al) nakho kunganciphisa ngempumelelo ukuminyana kwesici kungqimba ye-nitride epitaxial futhi kuthuthukise kakhulu ukusebenza nokuphila kwamadivayisi we-nitride semiconductor. Ngokusekelwe ku-AlGaN, umtshina oyimpumputhe wekhwalithi ephezulu usetshenziswe ngempumelelo.

5. Ukusetshenziswa kwezitsha zobumba kanye nezinto eziphikisayo

I-Aluminium Nitride ingasetshenziswa ku-ceramic sintering yesakhiwo; Izitsha zobumba ezilungisiwe ze-Aluminium Nitride azinazo nje izinto ezingcono zemishini namandla aguquguqukayo kune-Al2O3 kanye ne-BeO Ceramics, kodwa futhi nobulukhuni obuphakeme nokumelana nokugqwala. Ngokusebenzisa ukumelana nokushisa nokuguguleka kwe-AlN Ceramics, ingasetshenziswa ukwenza izitsha, izitsha ze-Al evaporation, kanye ezinye izingxenye ezinezinga lokushisa eliphezulu ezimelana nokugqwala. Ngaphezu kwalokho, izitsha zobumba ezihlanzekile ze-AlN zamakristalu angenambala abonisa ngale, anezici ezinhle kakhulu zokubona, angasetshenziswa njengeceramics ebonisa ngale kumadivayisi optical ka-elekthronikhi kanye nemishini yamafasitela e-infrared anezinga lokushisa eliphezulu kanye nenamathela evikela ukushisa elungisa kabusha.
