Sapphire wafer / saapphire substrate

Safiri ndeyoko yeCorundu boka remaminerari. Iyo inozivikanwa kubatana kwenziyo yekristaro. Iyo ndeyavo yeTrigonal Crystal system. Iyo Crystal Space Boka iri r3c. Iyo huru yemakemikari manhau ndeye AI2O3. Izvo zvinyorwa zvine mode kuomarara kweinosvika 9, yechipiri chete kune daimani. Sapphire ine yakanaka yemakemikari kugadzikana, kugadzirira kugadzirira mutengo uye akura tekinoroji, saka chave chinhu chikuru chinotsauka cheGan-based optoelectronic michina. Mukuwedzera, ine zvizere dielectric uye michina zvivakwa, uye inoshandiswa zvakanyanya muflat panel. Silicon Subasserer zvakare inoshandiswa zvakanyanya seyakajeka zvinhu. Iyo silicon nzvimbo yakarongedzwa muchimiro chehexagonal uye yakatsemuka tembiricha yakakura, iyo inokodzera kukudzwa kwakasimba kwekristasi imwechete uye inoshandiswa zvakanyanya. Nekudaro, iyo hurukuro huru dzehunyanzvi mukuita kuti ger-based leds pane silicon substrate is latice mismatch uye inobata mismara. Iyo LATTE MISTBT pakati peSilicon uye Galicium Nitride inoverengeka kakawanda iyo yeSilicon nitride, iyo inogona kukonzera matambudziko ekupaza.

Iyo semiconductor munda kazhinji inoshandisa sic seyinonyura zvinyorwa. Iyo inovimbika yekuita silicon nitride yakakwira kupfuura iyo yesafire. Zviri nyore kutsamwisa kupisa kupfuura safiro uye ine zvirinani untistatic kugona. Nekudaro, mutengo weSilicon nitride yakakwirira kwazvo kupfuura iyo yesafiro, uye mutengo wekutengesa kugadzirwa kwakakwirira. Kunyangwe silicon nitride senSimber inogona zvakare kuve zvakare indiwi, ivo vanodhura uye havana mashandiro epasi rose. Mamwe midziyo inonyinyoka yakadai seGNO, Zno, etc. ichiri mukutsvaga nekuvandudza nhanho, uye kuchine nzira refu yekuenda kubva mukushanda.

Paunenge uchisarudza substrate, zvinodikanwa kuti ufunge nezve kufanana kwezvinhu zvinotsiva uye zvinhu zvechinyorwa. Iko kuremara kweiyo subsity inodiwa kuti ive yakaderera, izvo zvemakemikari zvidiki, tembiricha idiki, hazvigone kuitwa nemakemikari nemufirimu we epitaxial, uye funga nezvemamiriro ezvinhu chaiwo. Kugadzira mitengo mukugadzira. Subhire substrate ine yakanaka yemakemikari kugadzikana, simba rakanyanya rekushisa, kusimba kwakanyanya kupisa pasi pemamiriro madiki, pasina hunyanzvi hwekugadzira, maitiro ekugadzira, uye anogona kutengeserana.
