Midziyo yeSapphire Ingot Yekukura Czochralski CZ Nzira yekugadzira maWafers eSapphire ane 2inch-12inch Mufananidzo Wakatsanangurwa

Tsananguro pfupi:

Zvishandiso zveSapphire Ingot Growth Equipment (Czochralski Method)isystem yemazuva ano yakagadzirirwa kukura kwesapphire single-crystal yakachena uye isina dambudziko. Nzira yeCzochralski (CZ) inobvumira kudzora kwakanyatsojeka kumhanya kwekudhonza kristalo yembeu (0.5–5 mm/h), kutenderera kwemuchina (5–30 rpm), uye tembiricha muiridium crucible, zvichigadzira axisymmetric crystals inosvika 300 mm mudhayamita. Muchina uyu unotsigira kudzora kweC/A-plane crystal orientation, zvichibvumira kukura kweoptical-grade, electronic-grade, uye doped safira (semuenzaniso, Cr³⁺ ruby, Ti³⁺ star safira).

XKH inopa mhinduro dzinobva kumativi ose, kusanganisira kugadzirisa michina (kugadzirwa kwewafer ye 2–12-inch), kugadzirisa mashandiro (defect density <100/cm²), uye kudzidziswa kwehunyanzvi, pamwe nekugadzirwa kwewafer dzinopfuura 5,000 pamwedzi dzekushandisa senge LED substrates, GaN epitaxy, uye semiconductor packaging.

Zvinhu zvirimo

Nheyo yekushanda

Nzira yeCZ inoshanda nematanho anotevera:
1. Kunyungudutsa Zvinhu Zvisina Kugadzirwa: Kuchena kwakanyanya Al₂O₃ (kuchena >99.999%) inonyungudutswa muiridium crucible pa2050–2100°C.
2. Nhanganyaya yeKrista yeMbeu: Krista yembeu inodzikiswa muchikamu chinonyunguduka, yozoteverwa nekukweva nekukurumidza kuti igadzire mutsipa (dhayamita <1 mm) kubvisa kutsemuka.
3. Kuumbwa Kwemafudzi Uye Kukura Kwemafudzi: Kumhanya kwekudhonza kunoderedzwa kusvika pa 0.2–1 mm/awa, zvichiwedzera zvishoma nezvishoma dhayamita yekristaro kusvika pahukuru hwainotarisirwa (semuenzaniso, 4–12 inches).
4. Kunyungudutsa uye Kutonhodza: Kristaro inotonhodzwa pa 0.1–0.5°C/min kuderedza kutsemuka kunokonzerwa nekupisa.
5. Mhando dzeKristaro Dzinoenderana:
Giredhi reMagetsi: Zvikamu zveSemiconductor (TTV <5 μm)
Giredhi reOptical: Mahwindo eUV laser (transmittance >90%@200 nm)
Mhando dzakaiswa dope: Ruby (Cr³⁺ concentration 0.01–0.5 wt.%), bhuruu resafire chubhu

Zvikamu zveSisitimu Yepakati

1. Sisitimu Yekunyungudutsa
Iridium Crucible: Inodzivirira kupisa kusvika 2300°C, haipindi ngura, inoenderana neyakanyunguduka yakakura (100–400 kg).
Induction Heating Furnace: Kudzora tembiricha kwakazvimirira munzvimbo dzakawanda (±0.5°C), magiraidi ekupisa akagadziridzwa.

2. Sisitimu yekudhonza nekutenderera
Mota yeServo Yakanyatsogadzirwa: Kukwanisa kudhonza 0.01 mm/h, kutenderera kwakasimba <0.01 mm.
Chisimbiso cheMagineti Chemvura: Kutapurirana kusingabatanidzi chinhu kuti chirambe chichikura (> maawa makumi manomwe nemaviri).

3. Sisitimu Yekudzora Kupisa
Kudzora PID Closed-Loop: Kugadzirisa simba remagetsi panguva chaiyo (50–200 kW) kuti simba remagetsi rigadzikane.
Dziviriro yeGasi Risina Kushanda: Musanganiswa weAr/N₂ (99.999% kuchena) kudzivirira oxidation.

4. Kuzvigadzira uye Kutarisa
Kutarisa dhayamita yeCCD: Mhinduro chaiyo (kururama ± 0.01 mm).
Thermography yeInfrared: Inotarisa chimiro chechimiro chesolid-liquid.
