Ibisobanuro bigufi:

LiTaO3 Wafer (lithium tantalate wafer), ibikoresho by'ingenzi mu bikoresho bya semiconductors na optoelectronics byo mu gisekuru cya gatatu, ikoresha ubushyuhe bwayo buri hejuru bwa Curie (610°C), inyura mu buryo bwagutse (0.4–5.0 μm), ingano ya piezoelectric (d33 > 1,500 pC/N), hamwe n'igihombo gito cya dielectric (tanδ < 2%)kugira ngo ihindure itumanaho rya 5G, ihuza ry'amafoto, n'ibikoresho bya quantum. Ikoresheje ikoranabuhanga rigezweho ryo gukora nka transport physical vapor (PVT)na chemical vapor deposition (CVD), XKH itanga X/Y/Z-cut, 42°Y-cut, na periodically poled (PPLT)wafers mu buryo bwa santimetero 2–8, ifite ubuso bugoye (Ra) <0.5 nm na micropipe density <0.1 cm⁻². Serivisi zacu zirimo Fe doping, chemical reduction, na Smart-Cut heterogeneous integration, ikemura filters optique zikora neza, infrared detectors, na quantum light sources. Ibi bikoresho bitera intambwe mu gukora miniaturization, gukoresha frequency nyinshi, no kudahungabana k'ubushyuhe, bikihutisha gusimbuza ikoranabuhanga ry'ingenzi mu ngo.

Ibiranga by'ingenzi

1. Imikorere y'amashanyarazi n'amatara
· Koefficient ya Electro-Optic: r33 igera kuri 30 pm/V (X-cut), iri hejuru ya 1.5× kurusha LiNbO3, bigatuma electro-optic modulation ya ultra-wideband (>40 GHz bandwidth).
· Uburyo bwa Broad Spectral Response: Intera yo kohereza amakuru hagati ya 0.4–5.0 μm (ubugari bwa mm 8), ifite uburebure bwa ultraviolet bugera kuri 280 nm, ikaba ari nziza cyane kuri lasers za UV na quantum dot devices.
· Koefficient nke ya pyroelectric: dP/dT = 3.5×10⁻⁴ C/(m²·K), ituma habaho ubusugire mu byuma bipima ubushyuhe bwinshi.

2. Imiterere y'ubushyuhe n'iy'imashini
· Ubushyuhe bwinshi butwara: 4.6 W/m·K (X-cut), inshuro enye ugereranyije na quartz, ikomeza -200–500°C mu gihe cy'ihindagurika ry'ikirere.
· Koreji yo kwagura ubushyuhe buke: CTE = 4.1×10⁻⁶/K (25–1000°C), ijyanye n'ipaki ya silikoni kugira ngo igabanye ubushyuhe.
3. Kugenzura no gutunganya neza inenge
· Ubucucike bwa micropipe: <0.1 cm⁻² (wafers za santimetero 8), ubucucike bwa dislocation <500 cm⁻² (byemejwe binyuze mu gushushanya KOH).
· Ubwiza bw'ubuso: CMP-yahinduwe kugeza kuri Ra <0.5 nm, yujuje ibisabwa ku buryo bwo kugorora bwa EUV.

Porogaramu z'ingenzi

Urwego	Ingero z'ikoreshwa	Ibyiza bya tekiniki
