O le a le semiconductor wafer?
O le semiconductor wafer o se fasi mea manifinifi, lapotopoto o mea semiconductor e avea ma faavae mo le fausiaina o fesoʻotaʻiga tuʻufaʻatasia (ICs) ma isi masini eletise. O le wafer e maua ai se mea mafolafola ma tutusa i luga o lo'o fausia ai vaega eseese fa'aeletoroni.
O le gaosiga o le wafer e aofia ai le tele o laasaga, e aofia ai le faʻatupuina o se tioata tele e tasi o mea semiconductor e manaʻomia, tipiina le tioata i ni fafie manifinifi e faʻaaoga ai se ili taimane, ona faʻamaeʻaina lea ma faʻamamā le faʻamaʻi e aveese ai soʻo se faaletonu poʻo ni mea leaga. O le fa'auluina o fafie e maualuga lona mafolafola ma lamolemole luga, lea e taua tele mo le fa'agasologa fa'asolo mai.
O le taimi lava e saunia ai wafers, latou te faia se faasologa o faiga gaosiga semiconductor, e pei o le photolithography, etching, deposition, ma le doping, e fausia ai mamanu lavelave ma laulau e manaʻomia e fausia ai vaega eletise. O nei fa'agasologa o lo'o fa'atele taimi i luga ole wafer e tasi e fa'atupu ai le tele o feso'ota'iga feso'ota'iga po'o isi masini.
A mae'a le fa'agasologa o le faiga, ona tu'u'ese'ese lea o tupe meata'i ta'ito'atasi e ala i le tipiina o le wafer i laina ua uma ona fa'atulaga. Ona afifiina lea o tupe meataalo eseese e puipuia ai ma tuʻuina atu fesoʻotaʻiga eletise mo le tuʻufaʻatasia i masini eletise.
Mea eseese i luga o le wafer
Semiconductor wafers e masani lava ona faia mai le silika tioata tasi ona o lona tele, mea lelei eletise, ma le fetaui ma faiga masani o gaosiga semiconductor. Ae ui i lea, e faʻatatau i faʻaoga faʻapitoa ma manaʻoga, o isi mea e mafai foi ona faʻaogaina e fai ai wafers. O nisi nei o fa'ata'ita'iga:
Silicon carbide (SiC) o se mea lautele bandgap semiconductor mea e ofoina atu meatotino sili atu faaletino pe a faatusatusa i mea masani. E fesoasoani e faʻaitiitia le tele ma le mamafa o masini faʻapitoa, modules, ma e oʻo lava i faiga atoa, aʻo faʻaleleia le lelei.
Uiga Autu ole SiC:
- -Apo'a Lautele:SiC's bandgap e tusa ma le faatoluina o le silicon, e mafai ai ona galue i le maualuga o le vevela, e oo atu i le 400°C.
- -Mata'aiga Mata'utia Fa'aleaga fanua:E mafai e le SiC ona tatalia e oo atu i le sefulu taimi o le eletise eletise o le silikoni, ma avea ai ma mea lelei mo masini eletise maualuga.
- -Avea maualuga:E fa'amama lelei e le SiC le vevela, fesoasoani i masini e fa'atumauina le maualuga o le vevela o le fa'aogaina ma fa'aumiumi lo latou ola.
- - Maualuluga Saturation Electron Drift Velocity:Faatasi ai ma le faaluaina o le saosaoa tafe o le silikoni, SiC e mafai ai ona maualuga le fesuiaiga o alalaupapa, fesoasoani i le faʻaititia o masini.
Talosaga:
-
-Eletonika Malosiaga:O masini eletise SiC e sili atu i le maualuga-voltage, maualuga-o le taimi nei, maualuga-vevela, ma le maualuga-televave siosiomaga, faʻaleleia atili le faʻaleleia o le malosi. O lo'o fa'aaogaina lautele i ta'avale eletise, nofoaga e fa'atauina ai, faiga fa'akomepiuta, felauaiga o nofoaafi, ma feso'ota'iga atamai.
-
-Fesootaiga Microwave:O masini GaN RF faʻavae SiC e taua tele mo fesoʻotaʻiga fesoʻotaʻiga uaea, aemaise lava mo nofoaga autu 5G. O nei masini e tu'ufa'atasia ai le lelei tele o le fa'avevelaina a le SiC ma le GaN's high-frequency, high-power RF output, ma avea ai i latou ma filifiliga sili mo feso'ota'iga telefoni feavea'i e sosoo ai.
Gallium nitride (GaN)o se vaega lona tolu-augatupulaga lautele bandgap semiconductor mea ma se bandgap tele, conductivity vevela maualuga, maualuga electron saosaoa tafetafea, ma uiga lelei fanua malepe. GaN masini o loʻo i ai faʻamoemoega faʻaoga lautele i nofoaga maualuga-televave, maualuga-saosaoa, ma maualuga-malosi e pei ole moli faʻasaoina o le malosi o le LED, faʻaaliga faʻaalia leisa, taʻavale eletise, grids atamai, ma fesoʻotaʻiga 5G.
Gallium arsenide (GaAs)o se mea semiconductor lauiloa mo le tele o taimi, eletonika mobility maualuga, malosiaga maualuga, maualalo leo, ma laina lelei. E faʻaaogaina lautele i optoelectronics ma microelectronics alamanuia. I optoelectronics, GaAs substrates e faʻaaogaina e gaosia ai le LED (diodes moli), LD (diodes laser), ma masini photovoltaic. I microelectronics, o loʻo faʻafaigaluegaina i latou i le gaosiga o MESFETs (metal-semiconductor field-effect transistors), HEMTs (high electron mobility transistors), HBTs (heterojunction bipolar transistors), ICs (integrated circuits), microwave diodes, ma Hall effect device.
Indium phosphide (InP)o se tasi o semiconductors taua III-V, lauiloa mo lona maualuga eletise eletise, sili atu le tetee o le radiation, ma le lautele o fusi. E faʻaaogaina lautele i le optoelectronics ma microelectronics alamanuia.
