Itandukaniro riri hagati ya polysilicon na monocrystalline silicon

Ibikoresho bya Silicon nibikoresho byibanze kandi byibanze mu nganda za semiconductor. Inzira igoye yumutwe wa Semiconductor inganda igomba kandi gutangira kubyara ibikoresho byibanze bya silicon.

Monocrystalline silicon izuba ryinshi

Monocrystalline silicon nuburyo bwa silicon yibanze. Iyo kwangirika silicon yibanze, atome ya Silicon itunganijwe muri diyama yambaye akazu kanini ka Crystal Nuclei. Niba aya nuclei ya kirisiti ikura hamwe nicyerekezo kimwe cyindege ya Crystal, ibi binyampeke bizahuzwa muburyo busa na korora kuri konte ya monocrystalline silicon.

Monocrystalline Silicon ifite imitungo yumubiri yicyuma cya quasi-ibyuma kandi ifite imikorere y'amashanyarazi, yiyongera hamwe n'ubushyuhe bworoshye. Muri icyo gihe, monocrystalline silicon nanone ifite amashanyarazi akomeye. Ultra-Yera Monocrystalline Silicon ni Seconductor yimbere. Imyitwarire ya Ultra-Yera-Monocrystal Silicon irashobora kunozwa wongeyeho ibimenyetso Nkayongereyeho ibimenyetso bya ⅴA

PolysiliconUmucyo w'izuba

Polysilicon nuburyo bwa silicon. Igihe yashongeshejwe na Silicon aringaniza yashimangiwe ku buryo butangaje, atome ya Silicon yateguwe muri Nuclei nyinshi cyane mu buryo bwa kamani. Niba aya marike ya kirisiti akura mu cyerekezo cya kirisiti butandukanye, ibi binyampeke bihuza kandi bikata muri polysilicon. Itandukanye na monocrystalline silicon, ikoreshwa muri elegitoroniki n'imisozi, no muri Amorhous Silicon, ikoreshwa mu bikoresho byoroheje kandiImirasire y'izuba Ubusitani

Itandukaniro nihuza hagati yombi

Muri monocrystalline silicon, imiterere ya kirisiti irasanzuye kandi irashobora kumenyekana nuburyo bumwe bwo hanze. Muri monocrystalline silicon, akazu ka kristu yose irakomeza kandi idafite imipaka. Kinini nini ni gake cyane muri kamere kandi biragoye gukora muri laboratoire (reba recrystallisation). Ibinyuranye, imyanya ya atome mu nyubako za Amorhous irabujijwe kugirango hashingiwe ku buryo bugufi.

Polycrystalline na subcrystalline proces bigizwe numubare munini wa kristu cyangwa mikorobe. Polysilicon nibikoresho bigizwe na kristu nyinshi za silicon. Ingirabuzimafatizo za Polycrystalline irashobora kumenya imiterere ningaruka zigaragara. Amanota ya Semiconductor harimo umutwe wizuba polysilicon yahinduwe muri monocrystalline silicon, bivuze ko kristu yahujwe muri polysiliilicon yahinduwe muri kristu nini. Monocrystalline Silicon ikoreshwa mugukora ibikoresho byinshi bya microelen-bishingiye kuri microeletronic. Polysilikoni arashobora kugera kuri 99.9999% ubuziranenge. Ultra-Wera-Weesilikoni nayo ikoreshwa munganda za semiconductor, nka 2 - metero 3 za metero 3 za metero nyinshi za polsilicon. Mu nganda za microelectronika, Polysilikoni ifite porogaramu kuri macro na micro na micro na micro. Igikorwa cyo gukora cya monocrystalline silicon Shyiramo inzira ya Czeckorasky, akarere gashonga na bridgman.

Itandukaniro riri hagati ya polysilicon na monocrystalline silicon igaragara cyane muburyo bwumubiri. Ukurikije imitungo n'imiterere y'amashanyarazi, Polysilicon iri munsi ya monocrystalline silicon. Polysilikoni arashobora gukoreshwa nkibikoresho fatizo byo gushushanya monocrystalline silicon.

1. Kubijyanye na anisotropi yimiterere ya mashini, imiterere ya optique hamwe numutungo wubushyuhe, biragaragara cyane kuruta monocrystalline silicon

2. Ku bijyanye n'amashanyarazi, imikorere y'amashanyarazi ya Polycrystalline Silicon itagira ingano kuruta iy'amafaranga ya monocrystalline silicon, cyangwa ndetse no gusa mu mashanyarazi

3, ukurikije ibikorwa bya chimique, itandukaniro riri hagati yabiri ni nto cyane, muri rusange ukoresha byinshi muri polysilicon
