Sezvo masekete akabatanidzwa aita indasitiri yenyika, akawanda semiconductor zvinhu zvakatsvagirwa uye kugadzirwa, uye Aluminium Nitride pasina mubvunzo ndeimwe yeanovimbisa semiconductor zvinhu.
Aluminium Nitride Performance Characteristics
Aluminium Nitride (AlN) ine hunhu hwekusimba kwepamusoro, vhoriyamu yakakwira resistivity, high insulation voltage, coefficient of thermal expansion, yakanaka kuenderana nesilicon, etc. Haisi kungoshandiswa senge sintering aid kana yekusimbisa chikamu chekugadzira ceramics asi inoshandiswawo. mumunda weceramic electronic substrates uye kurongedza zvinhu, izvo zvave kuwedzera mumakore achangopfuura, uye kuita kwayo kunodarika kweAlumina. Aluminium Nitride ceramics ine yakanakisa kuita kwese, yakanakira semiconductor substrates uye zvimiro zvekurongedza zvinhu, uye ine yakakosha yekushandisa mukana muindasitiri yemagetsi.
Kushandiswa kweAluminium Nitride
1. Piezoelectric device applications
Aluminium Nitride ine high resistivity, high thermal conductivity, uye yakaderera coefficient yekuwedzera yakafanana nesilicon, iyo ndiyo yakakodzera zvinhu zvepamusoro-tembiricha uye yakakwirira-simba zvemagetsi zvigadzirwa.
2. Electronic packaging substrate zvinhu
Beryllium Oxide, Alumina, Silicon Nitride, uye Aluminium Nitride ndezvimwe zvezvinhu zvinonyanya kushandiswa kushandiswa kweceramic substrates.
Pakati pezvinhu zviripo zveceramic zvinogona kushandiswa se substrate zvinhu, Silicon Nitride ceramics ine yakanyanya kuchinjika simba, yakanaka kupfeka kuramba, uye yakanakisa yakazara mamechanicha emidziyo yeceramic zvinhu, nepo coefficient yavo yekuwedzera kupisa iri idiki. Aluminium Nitride ceramics ine yakakwira yekupisa conductivity, yakanaka yekupisa kuvhundutsa kuramba, uye ichine yakanaka michina zvivakwa pakupisa kwakanyanya. Zvinogona kutaurwa kuti, kubva pakuona kwekuita, Aluminium Nitride uye Silicon Nitride iye zvino ndiyo inonyanya kukodzera kushandiswa semagetsi ekugadzirisa substrate zvinhu, asi vanewo dambudziko rinowanzoitika: mutengo wavo wakakwirira.
3. Kushandisa kune zvinhu zvinobudisa chiedza
Panyaya yephotoelectric conversion performance, aluminium nitride (AlN) ine yakananga bandgap semiconductor bhendi kureba kwe6.2 eV, iyo yakakwirira kupfuura indirect bandgap semiconductor. AlN, sechinhu chakakosha chebhuruu uye ultraviolet chiedza-emitting material, inoshandiswa mu ultraviolet uye yakadzika ultraviolet chiedza-emitting diodes, ultraviolet laser diodes, ultraviolet detectors, etc. AlN neIII-group nitrides seGaN neInN inogonawo kuumba yakasimba inopfuurira. mhinduro, uye bhendi gap ye ternary kana quaternary alloy inogona kugadziriswa nguva dzose kubva kubhendi rinooneka kusvika kune yakadzika ultraviolet band, zvichiita kuti ive yakakosha yepamusoro-yekuita chiedza-emitting material.
4. Kushandisa kune substrate zvinhu
AlN crystal ndiyo yakakodzera substrate yeGaN, AlGaN, uye AlN epitaxial zvinhu. Kuenzaniswa nesafire kana SiC substrates, AlN neGaN vane zvirinani kupisa kwemafuta uye kuenderana kwemakemikari, uye kushushikana pakati pe substrate uye epitaxial layer idiki. Nokudaro, makristasi eAlN seGaN epitaxial substrates anogona kuderedza zvakanyanya kuwanda kwehurema mumudziyo uye kuvandudza kushanda kwayo, iyo ine tarisiro yakanaka kwazvo yekushandiswa mukugadzirira kwepamusoro-tembiricha, yakakwirira-frequency, uye simba remagetsi emagetsi. Pamusoro pezvo, kushandisa AlN crystals seAlGaN epitaxial material substrate ine high aluminium (Al) zvikamu zvinogonawo kuderedza zvinobudirira defect density mu nitride epitaxial layer uye inovandudza zvikuru kushanda uye hupenyu hwehupenyu hwe nitride semiconductor madivayiri. Kubva paAlGaN, yemhando yepamusoro-soro yekuona mapofu yakashandiswa zvinobudirira.
5. Kushandisa kune ceramics uye refractory zvinhu
Aluminium Nitride inogona kushandiswa mukugadzirwa kweceramic sintering; Yakagadzirirwa Aluminium Nitride Ceramics haina kungoita zvirinani zvemakina uye simba rekuchinjika kupfuura Al2O3 uye BeO ceramics, asiwo yakakwirira kuomarara uye kushorwa kwekudzivirira. Uchishandisa kupisa uye kunyura kwekudzivirira kweAlN ceramics, inogona kushandiswa kugadzira crucibles, Al evaporation ndiro, uye. dzimwe nzvimbo dzepamusoro-tembiricha dzinodzivirira ngura. Uye zvakare, yakachena AlN ceramics yemakristaro asina ruvara akajeka, ane yakanakisa optical zvivakwa, anogona kushandiswa seyakajeka Ceramics yemagetsi optical zvishandiso uye midziyo yekumusoro-tembiricha infrared mahwindo uye inogadzirisa kupisa-inodzivirira coating.
