Zvakanakira zveKyropoulos (KY) Sapphire Crystal Kukura Equipment
Iyo Kyropoulos (KY) nzira-yakavakirwa safire kristaro kukura michina inopa isingaenzaniswi hunyanzvi hwakanakira, ichiimisa seyekucheka-kumucheto mhinduro yekugadzirwa kwemaindasitiri. Mabhenefiti akakosha anosanganisira:
1. Huru-Diameter Kugona—: Kukwanisa kurima makristasi esafire anosvika 12 inches (300 mm) , mudhayamita, zvichiita kuti kugadzirwa kwepamusoro-soro kwewafers uye optical components for advanced applications seGaN epitaxy nemafafitera egiredhi remauto.
2. Ultra-Low Defect Density: Inowana dislocation densities <100/cm² kuburikidza neyakagadziridzwa dhizaini yemumunda uye tembiricha chaiyo gradient kutonga, kuve nechokwadi chepamusoro chekristaro kuperera kune optoelectronic zvishandiso.
3. High-Quality Optical Performance : Inoendesa transmittance> 85% kuyambuka inoonekwa kune infrared spectra (400–5500 nm), yakakosha kune UV laser windows uye infrared optics.
4. Yepamberi Otomatiki: Inoratidzira servo-inotyairwa yekudhonza masisitimu (± 0.01 mm kunyatsojeka) uye magineti fluid rotary seals (0–30 rpm stepless control), kuderedza kupindira kwevanhu uye kusimbisa kuenderana.
5. Flexible Doping Options: Inotsigira gadziriso nemadopants akaita seCr³⁰ (yeruby) uye Ti³⁰ (yenyeredzi safiro), ichipa misika yeniche mune optoelectronics uye zvishongo.
6. Kushanda Kwesimba: Yakakwenenzverwa thermal insulation (tungsten-molybdenum crucible) inoderedza kushandiswa kwesimba kusvika ku80–120 kWh/kg, kukwikwidza nedzimwe nzira dzekukura.
7. Scalable Production: Inowana kubuda pamwedzi kwe5,000+ wafers, nekukurumidza kutenderera nguva (8-10 mazuva e30-40 kg makristasi), yakasimbiswa neanopfuura mazana maviri epasi rose kuiswa.
.
8. Kugara Kwemauto-Gredhi: Inosanganisa madhizaini asingachinji nemwaranzi uye zvinhu zvinodzivirira kupisa (zvinoshingirira 10¹⁶ n/cm²), zvakakosha pakushandisa muchadenga nenyukireya.
Aya magadzirirwo anosimbisa nzira yeKY seye goridhe chiyero chekugadzira yakakwirira-inoshanda makristasi esafire, kutyaira kufambira mberi mu5G kutaurirana, quantum computing, uye tekinoroji yekudzivirira.
