Nzira yeSapphire Crystal Growth Furnace KY Kyropoulos yekugadzira Sapphire Wafer neOptical Window

Sapphire Crystal Growth Furnace KY Kyropoulos Method yeSapphire Wafer neOptical Window Production Mufananidzo Wakaratidzwa

Tsananguro pfupi:

Iyi michina yekukura kwekristaro yesafire inoshandisa nzira yepamusoro-soro yeKyropoulos (KY), yakagadzirirwa kukura kwekristaro imwe chete yesafire ine dhayamita hombe, isina kuremara zvakanyanya. Nzira yeKY inobvumira kudzora kwakaringana kwekudhonza kwekristaro yembeu, kumhanya kwekutenderera, uye tembiricha, zvichibvumira kukura kwekristaro yesafire kusvika 300 mm (300 mm) dhayamita pakupisa kwakanyanya (2000–2200°C). Masisitimu eXKH eKY-method anoshandiswa zvakanyanya mukugadzira maindasitiri e2–12-inch C/A-plane safire wafers nemahwindo e optical, zvichiita kuti pave nekubuda kwemayuniti makumi maviri pamwedzi. Midziyo iyi inotsigira maitiro ekushandisa doping (semuenzaniso, Cr³⁰ doping yekugadzirwa kweruby) uye inopa mhando yekristaro ne:

Kuwanda kwenzvimbo isina kugadzikana <100/cm²

Kutumira >85% @ 400–5500 nm

Zvinhu zvirimo

Nheyo yekushanda

Nheyo huru yenzira yeKY inosanganisira kunyungudutsa zvinhu zvakacheneswa zvakanyanya zveAl₂O₃ muchikamu chetungsten/molybdenum pa2050°C. Kristaro yembeu inodzikiswa muchikamu chekunyunguduka, ichiteverwa nekudzora (0.5–10 mm/h) uye kutenderera (0.5–20 rpm) kuti uwane kukura kwe α-Al₂O₃ makristaro ega ega. Zvinhu zvikuru zvinosanganisira:

• Makristasi makuru (akakwirira. Φ400 mm × 500 mm)
• Sapphire yemhando ye optical ine stress yakaderera (wavefront distortion <λ/8 @ 633 nm)
• Makristasi akadhayiwa (semuenzaniso, Ti³⁰ doping yenyeredzi sapphire)

Mabhenefiti eKyropoulos (KY) Sapphire Crystal Growth Equipment

Midziyo yeKyropoulos (KY) inoshandisa nzira yekukura kwekristaro yesapphire inopa mabhenefiti asina kujairika, ichiiisa semhinduro yemazuva ano yekugadzira zvinhu mumaindasitiri. Mabhenefiti makuru anosanganisira:

1. Kugona Kukura: Kukwanisa kurima makristaro esapphire anosvika masendimita 300 (300 mm) mudhayamita, zvichigonesa kugadzirwa kwemawafers nezvikamu zve optical zvinobudirira pakushandisa kwepamusoro senge GaN epitaxy nemahwindo emhando yemauto.

2. Kuwanda Kwemadhiragi Akaderera Zvikuru: Inoita kuti dhiragi ribude zvakanaka pasi pe100/cm² kuburikidza nekugadzirwa kwenzvimbo yekupisa kwakanyatsogadzirwa uye kudzora tembiricha nemazvo, zvichiita kuti girazi rive rakasimba pamidziyo yemagetsi.

3. Kushanda KwemaOptical Kwemhando Yepamusoro: Inopa transmittance >85% inoonekwa neinfrared spectra (400–5500 nm), yakakosha kumahwindo eUV laser uye infrared optics.

4. Advanced Automation: Ine michina yekudhonza inotungamirwa neservo (± 0.01 mm chaiyo) uye magnetic fluid rotary seals (0–30 rpm stepless control), inoderedza kupindira kwevanhu uye inowedzera kugadzikana.

5. Sarudzo dzekushandisa zvinodhaka dzinochinjika: Inotsigira kugadzirisa zvinhu uchishandisa zvinhu zvakaita seCr³⁰ (yeruby) uye Ti³⁰ (yenyeredzi yesafire), zvichibatsira misika midiki yezvigadzirwa zvemagetsi nezvishongo.

6. Kushanda Nesimba: Kudzivirira kupisa kwakanyanya (tungsten-molybdenum crucible) kunoderedza kushandiswa kwesimba kusvika ku 80–120 kWh/kg, zvichikwikwidzana nedzimwe nzira dzekukura.

7. Kugadzirwa Kunokwanisika: Kunoburitsa mawafer anopfuura zviuru zvishanu pamwedzi nenguva dzinokurumidza kutenderera (mazuva 8-10 emakristaro anorema 30-40 kg), zvakasimbiswa nemakambani anopfuura mazana maviri pasi rose.
.
8. Kugara Kwenguva Yemauto: Inosanganisira magadzirirwo anodzivirira mwaranzi uye zvinhu zvinodzivirira kupisa (zvinodzivirira 10¹⁶ n/cm²), zvakakosha pakushandiswa kwendege nenyukireya.
Izvi zvitsva zvinosimbisa nzira yeKY senzira yakanaka yekugadzira makristaro esapphire anoshanda zvakanyanya, zvichitungamira kufambira mberi mukutaurirana kwe5G, quantum computing, uye matekinoroji ekudzivirira.

Mabasa eXKH

XKH inopa mhinduro dzakakwana dzekugadzirisa masisitimu ekukura kwekristaro yesapphire, kusanganisira kuisa, kugadzirisa mashandiro, uye kudzidziswa kwevashandi kuti tive nechokwadi chekubatanidzwa kwekushanda zvakanaka. Tinopa mabikirwo ekukura akagadziriswa kare (50+) akagadzirirwa zvinodiwa zvakasiyana-siyana zvemaindasitiri, zvichideredza zvakanyanya nguva yeR&D kune vatengi. Kune maapplication akasarudzika, masevhisi ekugadzira akagadziriswa anogonesa kugadzirisa cavity (Φ200–400 mm) uye masisitimu epamusoro ekushandisa doping (Cr/Ti/Ni), achitsigira zvikamu zve optical zvinoshanda zvakanyanya uye zvinhu zvinodzivirira mwaranzi.

Mabasa anowedzera kukosha anosanganisira kugadziriswa mushure mekukura kwechinhu chakadai sekucheka, kukuya, nekupukuta, pamwe chete nezvigadzirwa zvesafire zvakaita sewafers, machubhu, uye matombo ematombo anokosha. Izvi zvinopa rubatsiro kubva kumagetsi emagetsi kusvika kumhepo. Rutsigiro rwedu rwehunyanzvi runovimbisa garandi yemwedzi makumi maviri nemana uye kuongororwa kuri kure kwenguva chaiyo, zvichiita kuti pave nenguva shoma yekushanda uye kushanda zvakanaka kwekugadzira.
