Iziko lokukhula kwe-silicon ye-Monocrystalline ziguqula izinto zokusetshenziswa ze-polysilicon zibe izinti ze-silicon zekhwalithi ephezulu ngokusebenzisa amasu afana ne-Czochralski (CZ) Czochralski noma indlela yendawo entantayo (FZ).

Umsebenzi oyinhloko: Ukushisisa okokusetshenziswa kwe-polysilicon eluhlaza kusimo esincibilikisiwe, okuqondisayo nokulawula ukukhula kwekristalu ngokusebenzisa amakristalu embewu ukuze kwakheke izinti ze-silicon ezine-monocrystalline orientation nosayizi wekristalu.

Izingxenye eziyinhloko:
Isistimu yokushisisa: Ihlinzeka ngendawo yokushisa ephezulu, ngokuvamile isebenzisa izifudumezi ze-graphite noma ukufudumeza kwe-high frequency induction.

I-Crucible: Isetshenziselwa ukubamba i-silicon encibilikisiwe, ngokuvamile eyenziwe nge-quartz noma i-graphite.

Uhlelo lokuphakamisa: lawula ukujikeleza nokuphakamisa isivinini sekristalu yembewu ukuze uqinisekise ukukhula kwekristalu okufanayo.

Uhlelo lokulawula umkhathi: Ukuncibilika kuvikelwe ekungcolisweni amagesi angasebenzi njenge-argon.

Isistimu yokupholisa: Lawula izinga lokupholisa lekristalu ukuze unciphise ingcindezi yokushisa.

Izici eziyinhloko zesithando somlilo se-silicon ye-monocrystalline

(1) Ukulawula ukunemba okuphezulu
Ukulawula izinga lokushisa: Lawula ngokunembile izinga lokushisa lokushisa (iphuzu lokuncibilika le-silicon licishe libe ngu-1414°C) ukuze uqinisekise ukuzinza kokuncibilika.
Ukulawula isivinini sokuphakamisa: isivinini sokuphakamisa i-crystal imbewu silawulwa yi-motor enembile (ngokuvamile i-0.5-2 mm / min), ethinta ububanzi be-crystal nekhwalithi.
Ukulawula isivinini sokuzungezisa: Lungisa isivinini sokuphenduka sembewu kanye ne-crucible ukuze uqinisekise ukukhula kwekristalu okufanayo.

(2) ukukhula kwekristalu kwekhwalithi ephezulu
Ukuminyana kwesici esiphansi: Ngokulungiselela amapharamitha wenqubo, induku ye-silicon ye-monocrystalline enesici esiphansi nokuhlanzeka okuphezulu ingatshalwa.
Amakristalu amakhulu: ama-silicon e-monocrystalline rods afinyelela kuma-intshi angu-12 (300 mm) ububanzi angatshalwa ukuze ahlangabezane nezidingo zemboni ye-semiconductor.

(3) Ukukhiqiza okuphumelelayo
Ukusebenza okuzenzakalelayo: Iziko zanamuhla zokukhula kwe-silicon ye-monocrystalline zifakwe izinhlelo zokulawula ezizenzakalelayo ukuze kuncishiswe ukungenelela okwenziwa ngesandla nokuthuthukisa ukusebenza kahle kokukhiqiza.
Idizayini eyonga amandla: Sebenzisa amasistimu wokushisisa nawokupholisa asebenzayo ukuze unciphise ukusetshenziswa kwamandla.

(4) Ukuguquguquka
Ifanele izinqubo ezihlukahlukene: indlela ye-CZ yokusekela, indlela ye-FZ nobunye ubuchwepheshe bokukhula kwekristalu.
Ihambisana nezinhlobonhlobo zezinto: Ngaphezu kwe-silicon ye-monocrystalline, ingasetshenziswa futhi ukukhulisa ezinye izinto ze-semiconductor (njenge-germanium, i-gallium arsenide).
