E faia i mea quartz synthetic maualuga-mama. I le avea ai ma mea e faʻaaogaina i le maualuga o le vevela, o le quartz vaʻa lagolago ua avea ma taʻavale lelei mo wafers, wafers silicon, substrates tioata ma isi vaega saʻo i le faʻasalalauina, annealing, oxidation, CVD (chemical vapor deposition) ma isi faʻagasologa ona o lo latou faʻamautuina lelei o le vevela, vailaʻau inertness ma ultra-umi le gaosiga o le ola ma fesoasoani i tagata faʻatau oloa gaosiga lelei.

Tala fa'atatau po'o meafaigaluega: 

Semiconductor diffusion, annealing, oxidation, ma le CVD (Chemical Vapor Deposition) faagasologa.

Malosiaga a le Kamupani

Semixlab Tekonolosi Co., Ltd ei ai 2 R & D nofoaga autu, 2 gaosiga faavae, 12 laina gaosiga, 150+ tagata faigaluega, ma R & D tupe teu faafaigaluega mo sili atu i le 30%. O la matou faʻasologa o oloa e masani ona faʻaaogaina i le LED, IC integrated circuit, lona tolu o augatupulaga semiconductor, photovoltaic ma isi pisinisi. Semixlab e malosi R&D, gaosiga ma tu'ufa'atasiga su'ega ma fa'amaoniga gafatia. I le taimi lava e tasi, o loʻo matou faʻaleleia pea a matou tekinolosi ma meafaigaluega faʻatasi ai ma le faʻafaigaluegaina o le fiasefulu miliona i le tausaga.

Faʻapitoa tautua

Ina ia fa'amalieina mana'oga 'ese'ese, matou te tu'uina atu 'au'aunaga fa'aganu'u fetu'una'i ma lagolagoina fa'atonuga fa'ata'oto nei:

Fa'amatalaga tetele: Fetuuna'i i mea eseese e pei o le 8 inisi ma le 12 inisi, po'o le fa'avasegaina o fausaga fa'apitoa e tusa ai ma ata fa'atau.

Togafitiga i luga ole laiga: Sandblasting filifiliga, faʻapipiʻi (pei o le faʻapipiʻi carbide silicon) ma isi faiga e faʻaleleia ai le faʻaogaina i faʻamatalaga patino.

Tu'ufa'atasiga tu'ufa'atasia: E mafai ona fa'atusaina ma poutū quartz, pa'u ma isi vaega e fausia ai se faiga fa'auma atoatoa.

Faiga fa'amautinoaga lelei

Su'ega o mea mata'utia: Fa'aulufale mai le oneone quartz mama maualuga, su'esu'eina e le ICP-MS (fa'apipi'i fa'aulu fa'atasi o le plasma mass spectrometry).

Fa'atonuga ole fa'agasologa: CNC machining sa'o + su'ega otometi, fa'apalepale vaega autu ≤±0.05mm.

Fa'amama afifi: Vasega 100 fa'amama le si'osi'omaga fa'apipi'i e 'alofia ai le fa'aleagaina o felauaiga.

Fa'aaliga fa'aoga masani

Semiconductor gaosiga: faʻaaogaina mo le maualuga o le vevela, faʻamaʻiina ma le faʻaogaina o ata manifinifi o faʻagogo i totonu o ogaumu faʻasalalau ma ogaumu tūsaʻo.

Alamanuia Photovoltaic: Aveina ma tuʻuina atu sela PERC ma TOPCon i le PECVD, faʻasalalauga phosphorus ma isi faiga.

Epitaxy LED: Tulaga sa'o ma le maualuga o le vevela epitaxial tuputupu a'e o mea safaira i masini MOCVD.

Matā'upu su'esu'e: Su'esu'e ma su'ega i falesu'esu'e ogaumu vevela maualuga ma si'osi'omaga vacuum.

1. Lelei maualuga maualuga teteʻe

O le lagolago va'a quartz e mafai ona tatalia siosiomaga vevela maualuga i luga ole 1200 ℃ mo se taimi umi, faʻatasi ai ma se faʻaopoopoga faʻalauteleina o le vevela (e tusa ma le 5.5 × 10⁻⁷ / ℃). E mafai lava ona faatumauina le mautu o le fausaga i lalo o le vave malulu ma le vevela tulaga, aloese mai le ta'e po'o le deformation e mafua mai i le vevela vevela, ma faʻamautinoa le toe faʻaleleia o le faagasologa.

2. Ultra-maualuga mama ma inertness vailaau

Faia i le 99.99% poʻo le sili atu le mama quartz oneone, leai se timuga, leai se faʻaleagaina, puipuia lelei ions uʻamea poʻo le faʻaleagaina o mea eleelea mai le faʻaleagaina o luga o le wafer i le vevela maualuga, aemaise lava mo faʻagasologa alualu i luma ma manaoga mama mama (e pei o le gaosiga o chip i lalo ole 7nm).

3. Fuafuaga sa'o lelei

O le pito i luga o le lagolago vaʻa o loʻo faʻapipiʻiina i le maualuga maualuga (roughness Ra≤0.2μm), faʻapipiʻiina i se fausaga pateni pateni, lea e mafai ona stably tauaveina substrates o lapopoa eseese (e pei o 8/12-inisi wafers), faʻamautinoaina faʻavevela toniga ma faʻasalalau kesi, ma faʻaleleia le tutusa o le faagasologa.

4. Ultra-umi auaunaga ola

Pe a faatusatusa i graphite masani po o sima feaveai, quartz mea e malosi tetee corrosion, maualalo fua faatatau gau i acidic / alkalina atemosifia, ma faʻaauau le faʻaaogaina taamilosaga e mafai ona oʻo atu i le 12-24 masina, faʻaitiitia ai le tau o tagata faʻatau.
