Semixlab muaj kev tshawb fawb thiab kev txhim kho zoo, kev tsim khoom thiab kev sim thiab kev txheeb xyuas kev sib xyaw ua ke. Tib lub sijhawm, peb pheej txhim kho peb cov thev naus laus zis thiab cov khoom siv nrog kev nqis peev ntawm kaum tawm lab ib xyoos.

Cov haujlwm pabcuam tshwj xeeb

Yuav kom ua tau raws li ntau yam kev xav tau, peb muab cov kev pabcuam hloov kho tau yooj yim thiab txhawb nqa cov kev hloov kho parameter hauv qab no:

Cov lus qhia txog qhov loj me: Hloov kho rau ntau yam substrates xws li 8 nti thiab 12 nti, lossis kho cov qauv tshwj xeeb raws li cov neeg siv khoom kos duab.

Kev kho qhov chaw: Xaiv tau xuab zeb, txheej (xws li silicon carbide txheej) thiab lwm yam txheej txheem los txhim kho kev siv tau rau hauv cov xwm txheej tshwj xeeb.

Kev koom ua ke ntawm cov khoom siv: Muaj peev xwm sib phim nrog cov ncej quartz, baffles thiab lwm yam khoom los tsim kom muaj lub kaw lus nqa khoom tiav.

Quality assurance system

Kev kuaj cov khoom siv raw: Cov xuab zeb quartz uas muaj cov khoom ntshiab siab, uas tau tshuaj xyuas los ntawm ICP-MS (inductively coupled plasma mass spectrometry).

Kev tswj cov txheej txheem: CNC precision machining + automated testing, qhov tseem ceeb dimension kam rau siab ≤ ± 0.05mm.

Kev ntim khoom huv si: Chav kawm 100 cov ntim khoom ib puag ncig huv si kom tsis txhob muaj kuab paug los ntawm kev thauj mus los.

Tej yam kev thov scenarios

Kev tsim khoom semiconductor: siv rau kev ua kom sov siab, oxidation thiab cov txheej txheem tso cov zaj duab xis nyias ntawm cov wafers hauv cov cub tawg diffusion thiab cov cub tawg ntsug.

Kev lag luam photovoltaic: Nqa thiab kis ntawm PERC thiab TOPCon hlwb hauv PECVD, phosphorus diffusion thiab lwm yam txheej txheem.

LED epitaxy: Qhov chaw tseeb thiab kev loj hlob ntawm sapphire substrates hauv MOCVD cov khoom siv.

Kev tshawb fawb teb: Cov khoom siv sintering thiab kev sim hauv chav kuaj kub thiab qhov chaw nqus tsev.

1. Zoo heev kub ua hauj

Lub nkoj txhawb nqa quartz tuaj yeem tiv taus qhov kub siab tshaj 1200 ℃ ntev, nrog rau qhov coefficient thermal expansion qis heev (kwv yees li 5.5 × 10⁻⁷ / ℃). Nws tseem tuaj yeem tswj tau qhov ruaj khov ntawm cov qauv hauv qab qhov txias thiab cua sov sai, zam kev tawg lossis deformation los ntawm kev ntxhov siab thermal, thiab ua kom cov txheej txheem rov ua dua.

2. Kev huv siab heev thiab kev tsis muaj tshuaj lom neeg

Ua los ntawm 99.99% lossis ntau dua cov xuab zeb quartz purity siab, tsis muaj nag lossis daus, tsis muaj kuab paug, zoo tiv thaiv cov hlau ions lossis cov khoom me me los ntawm kev ua qias tuaj ntawm qhov kub siab, tshwj xeeb tshaj yog haum rau cov txheej txheem siab heev nrog cov kev cai huv huv (xws li kev tsim khoom chip hauv qab 7nm).

3. Kev tsim qauv zoo meej

Qhov saum npoo ntawm lub nkoj txhawb nqa yog polished nrog qhov tseeb siab (roughness Ra≤0.2μm), nruab nrog lub qauv qhov patented, uas tuaj yeem nqa cov substrates ntawm ntau qhov ntau thiab tsawg (xws li 8/12-nti wafers), xyuas kom meej tias muaj cua sov sib xws thiab cov roj ncig, thiab txhim kho cov txheej txheem sib xws.

4. Ultra-ntev kev pab cuam lub neej

Piv nrog cov graphite lossis ceramic nqa khoom ib txwm muaj, cov ntaub ntawv quartz muaj zog tiv taus corrosion, qis poob hauv acidic / alkaline atmospheres, thiab kev siv tas mus li tuaj yeem ncav cuag 12-24 lub hlis, txo cov nqi ntawm cov neeg siv khoom.
