Kambani yeFraunhofer IISB (Institute for Integrated Systems and Device Technology) iri muErlangen pamwe nekambani inogadzira masisitimu eplasma emicrowave & radio frequency PVA TePla AG iri muWettenberg vari kuunganidza hunyanzvi hwavo muJoint Lab yekugadzira makristaro ealuminium nitride (AlN).
Sekutanga muEurope, kubatana uku kunogonesa kugadzirwa kwezvikamu zvidiki zve monocrystalline AlN substrates zvine dhayamita ye 2-inches zvezvinangwa zveR&D. Izvi zvinovandudza zvakanyanya kuwanikwa kweAlN substrates muEurope, izvo zvinokurumidzisa kugadzirwa kwemidziyo nemasisitimu akavakirwa paAlN uye kuchinjira kwavo kumashandisirwo emaindasitiri.
Aluminium nitride ndeimwe yezvinhu zvinovimbisa zvikuru kuchizvarwa chinotevera chemagetsi anoshanda zvakanyanya. Semuchina wemagetsi wepamusoro-soro (UWBG), AlN inovhura mikana mitsva mu photonics, magetsi emagetsi, magetsi emagetsi ane frequency yakakwira, uye magetsi anoshanda mumamiriro ezvinhu akaomarara. Kusvika pari zvino, kushomeka kweAlN substrates dzemhando yepamusoro, nzvimbo yakakura uye isingadhuri kwave kuchidzivisa kugadzirwa kwemasystem emagetsi akavakirwa paAlN.
"NeJoint Lab, tiri kugadzira hwaro hwekuona kuti zvinhu zveAlN zvinobva kuEurope zvinowanika zvakavimbika, nokudaro tichivhura mikana mitsva yechizvarwa chinotevera chezvigadzirwa zveAlN zvinoshanda zvakanyanya," anodaro Dr Sven Besendörfer, mutungamiri weboka rezvinhu zve nitride uye ane basa rekugadzira zvinhu zveAlN kuFraunhofer IISB. "Pamwe chete nePVA TePla, tiri kupa ruzivo rwedu mukukura kwemakristaro emaindasitiri, nokudaro tichigadzira zvinodiwa kuti zvishandiswe mukugadzirwa kwekongiri."
Tekinoroji yemidziyo yakasimbiswa inosangana nehunyanzvi hwekuita kwayo
Murabhoritari yekubatana, Fraunhofer IISB iri kushandisa tekinoroji yayo yePVT (physical vapor transport) kugadzira makristaro eAlN ane mainch maviri. Mukuita uku, upfu hweAlN hunopfuudzwa muchombo patembiricha iri pamusoro pe2000°C uye hunoiswa pakristaro yembeu. PVA TePla inopa masisitimu ePVT echinangwa ichi, ayo atove kushandiswa pasi rese kumakristaro esilicon carbide (SiC) ane dhayamita ye8 inch uye ikozvino akagadzirirwa kukura kwemakristaro eAlN ane mainch maviri.
Nekuda kwehunyanzvi hwekuita zvinhu hwakapihwa neFraunhofer IISB, timu yePVA TePla yakakurumidza kugadzira makristaro eAlN emhando yakafanana munzvimbo dzayo. Joint Lab inotarisa pakugadzirwa kwemakristaro eAlN e2-inch. Kugadzirwa kuri kuwedzera zvishoma nezvishoma kuti kugadzirise kugadzikana kwemaitiro, kuberekana, goho uye mitengo.
“Nealuminium nitride, tiri kushanda nesimba kugadzira chizvarwa chinotevera chetekinoroji chinotevera SiC,” anodaro Dr Jan Pfeiffer, mutevedzeri wemutungamiri weR&D kuPVA TePla. “Kuburikidza neJoint Lab, tinogona kusanganisa zvakananga hunyanzvi hwedu hwemidziyo neruzivo rwemaitiro eFraunhofer IISB, zvichitigonesa kupa mhinduro dzakananga kumusika kune vatengi vedu vepasi rose pakutanga,” anowedzera. “Chinangwa chedu chatinogovana ndechekukurudzira kukura kwemusika muchikamu cheAlN kuburikidza nezvikamu zvakakodzera uye kutsigira makambani ari kutsvaga kupinda muchikamu ichi sevashandi vetekinoroji nemidziyo yakakodzera uye ruzivo rwakakodzera rwemaitiro.”
Kusimbisa hutongi hweEurope kuburikidza nekukura kwemaindasitiri
Makristaro eAlN anogadzirwa muJoint Lab anogadziriswazve paFraunhofer IISB kuita masubstrate eAlN akagadzirira epi uye, kuburikidza nekambani yekutsvagisa nekugadzira zvigadzirwa yeErlangen LZE GmbH, yakanyatsoendeswa mukuvandudza maindasitiri nekuwedzera. "Kuti ive nesimba remasemiconductor muEurope, zvakakosha kuti zvinhu zvitsva zvikuru zvisangogadzirwa chete asiwo zvitamiswe nekukurumidza mukushandiswa kwemaindasitiri uye kugadzira kukosha kunogona kuwedzerwa," anodaro mukuru weLZE Dr Christian Forster. "Nemusika wayo wetekinoroji yepamusoro, LZE GmbH inopa makambani nemasangano ekutsvagisa mukana wepasi rose wekuwana masubstrate eAlN. Nenzira iyi, tinobatsira kuona kuti maapplication anovimbisa emisika yemaindasitiri yakawanda anouya kumusika nekukurumidza."
