Kufotokozera Kwachidule:

LiTaO3 Wafer (lithium tantalate wafer), chinthu chofunikira kwambiri pa semiconductors ndi ma optoelectronics am'badwo wachitatu, imathandizira kutentha kwake kwa Curie (610°C), mawonekedwe owoneka bwino (0.4–5.0 μm), piezoelectric coefficient (d33 > 1,500 ditoelectric 2%), ndi kutayika kwatsika Kulumikizana kwa 5G, kuphatikiza zithunzi, ndi zida za quantum. Pogwiritsa ntchito matekinoloje apamwamba kwambiri opangira zinthu monga transport vapor transport (PVT) ndi chemical vapor deposition (CVD), XKH amapereka X/Y/Z-cut, 42°Y-cut, and periodically poled poled (PPLT)mumawonekedwe a mainchesi 2–8, okhala ndi makulidwe a pamwamba (Ra) <0.1 cm ² ndi microdensity <0.1 ² Ntchito zathu zikuphatikizapo Fe doping, kuchepetsa mankhwala, ndi Smart-Cut heterogeneous integration, kuthana ndi zosefera zowoneka bwino kwambiri, zowunikira ma infrared, ndi magwero a kuwala kwa quantum. Izi zimapangitsa kuti pakhale zotsogola mu miniaturization, magwiridwe antchito apamwamba kwambiri, komanso kukhazikika kwamafuta, kufulumizitsa kulowetsa m'malo m'nyumba muukadaulo wofunikira.

Makhalidwe Ofunikira

1.Magwiridwe Amagetsi ndi Owoneka
· Electro-Optic Coefficient: r33 imafika ku 30 pm/V (X-cut), 1.5× apamwamba kuposa LiNbO3, kupangitsa kuti Ultra-wideband electro-optic modulation (> 40 GHz bandwidth).
Mayankho a Broad Spectral: Kutumiza kwamtundu wa 0.4-5.0 μm (mamilimita 8 makulidwe), okhala ndi m'mphepete mwa mayamwidwe a ultraviolet otsika mpaka 280 nm, abwino kwa ma laser a UV ndi zida za madontho a quantum.
· Low Pyroelectric Coefficient: dP/dT = 3.5×10⁻⁴ C/(m²·K), kuonetsetsa kukhazikika kwa masensa a infrared a kutentha kwambiri.

2. Thermal ndi Mechanical Properties
· High Thermal Conductivity: 4.6 W/m·K (X-cut), quadruple ya quartz, kusunga -200-500 ° C kutentha kwa njinga.
· Low Thermal Expansion Coefficient: CTE = 4.1 × 10⁻⁶/K (25-1000 ° C), yogwirizana ndi silicon phukusi kuti muchepetse kupsinjika kwa kutentha.
3.Defect Control and Processing Precision
Kachulukidwe ka Micropipe: <0.1cm⁻² (zowotcha ma inchi 8), kusasunthika kwapang'onopang'ono <500cm⁻² (kutsimikiziridwa kudzera pa KOH etching).
· Ubwino Pamwamba: CMP yopukutidwa mpaka Ra <0.5 nm, ikukwaniritsa zofunikira za EUV lithography-grade flatness.

Ntchito za XKH

1. Custom Wafer Fabrication

· Kukula ndi Kudula: 2-8-inch wafers ndi X/Y/Z-cut, 42°Y-cut, and custom angular cuts (±0.01° tolerance).

· Doping Control: Fe, Mg doping kudzera mu njira ya Czochralski (concentration range 10¹⁶–10¹⁹cm⁻³) kuti apititse patsogolo ma electro-optic coefficients ndi kukhazikika kwamafuta.

2.Advanced Process Technologies
pa
· Periodic Poling (PPLT): Ukadaulo wa Smart-Cut wa zophika za LTOI, kukwaniritsa ± 10 nm domain nthawi yolondola komanso kutembenuka kwafupipafupi (QPM).

3.Mayendedwe Oyendetsera Ubwino
pa
Kuyesa-Kumapeto-kumapeto: Raman spectroscopy (polytype verification), XRD (crystallinity), AFM (surface morphology), ndi kuyesa kufanana kwa kuwala (Δn <5×10⁻⁵).

4.Global Supply Chain Support
pa
· Mphamvu Zopanga: Kutulutsa kwa mwezi uliwonse> 5,000 wafers (8-inchi: 70%), ndi kutumiza kwadzidzidzi kwa maola 48.

· Logistics Network: Kufalikira ku Europe, North America, ndi Asia-Pacific kudzera pamayendedwe apamlengalenga/panyanja okhala ndi zotengera zoyendetsedwa ndi kutentha.
