Germanium Wafers Ua li cas?
Zone Refining
Thawj kauj ruam hauv kev tsim germanium wafers hu ua zone refining. Nws yog qee zaum hu ua zone melting, uas yog ib qho kev piav qhia zoo ntawm cov txheej txheem entails.Lub sijhawm no thaum ntxov, lub caij yog purified los ntawm concentrating impurities. Qhov no yog ua los ntawm melting ib cheeb tsam ntawm germanium. Qhov no tso cai rau thaj tsam molten maj mam yaj cov impurities tam sim ntawd. Ob qho tib si germanium thiab silicon yuav tsum nyob rau hauv lub xeev yuav luag zoo tag nrho los siv rau wafer ntau lawm.
Txoj Kev Czochralski
Ib yam li silicon, germanium dhau los ntawm Czochralski txoj kev los tsim cov ingots. Qhov no tso cai rau kev txiav yooj yim dua thiab yog vim li cas wafers tshwm nyob rau hauv cov duab.
Slicing, sib tsoo, thiab Etching
Thaum lub germanium tau zoo li tus ingot, nws yog npaj txhij mus hlais mus rau hauv lub recognizable duab thiab loj ntawm ib tug wafer. Qhov no yog lub tshuab computer-automated txheej txheem uas tso cai rau peb los tsim wafers uas yog qhov tseeb thickness txhua lub sij hawm rau nws yav tom ntej daim ntaub ntawv.Thaum lub slicing tiav lawm, cov npoo yog diced, thiab lawv undergo etching. Thaum lub sij hawm no, cov khaubncaws sab nraud povtseg ntawm wafer raug tshem tawm.
Polishing thiab kuaj
Tom qab cov germanium wafers tiav lawm, tseem tshuav ob peb kauj ruam ntxiv kom paub tseeb tias lawv yuav luag zoo tag nrho.wafers ces polished los tsim ib qho chaw tiaj tus uas nyias nyias thiab muaj zog li sai tau. Hauv qee qhov xwm txheej, thaum lub wafer xav tau nyias dua li niaj zaus, ob sab yuav polished. Qhov no yog hu ua ob sab polished wafer.Qhov kawg theem yuav raug kuaj, uas yog ua tiav kom paub tseeb tias cov tiav lawm wafers yuav ua tau zoo raws li ib tug semiconductor.
Germanium wafers muaj cov khoom siv semiconductor. Nws ua lub luag haujlwm tseem ceeb hauv kev txhim kho cov khoom siv hluav taws xob hauv lub xeev thiab cov khoom siv hluav taws xob hauv lub xeev. Lub melting ceev ntawm germanium yog 5.32 g / cm 3. Germanium tej zaum yuav raug cais raws li ib tug tawg khiav ri niab hlau. Germanium muaj cov tshuaj ruaj khov thiab tsis cuam tshuam nrog huab cua lossis dej vapor ntawm chav tsev kub. Txawm li cas los xij, ntawm 600 txog 700 degree, germanium dioxide tau tsim sai. Nws tsis ua haujlwm nrog hydrochloric acid lossis dilute sulfuric acid. Thaum cov concentrated sulfuric acid yog rhuab, germanium yuav maj mam yaj. Hauv nitric acid thiab aqua regia, germanium yog yooj yim soluble. Kev sib cuam tshuam ntawm alkali tov thiab germanium tsis muaj zog heev, tab sis molten alkali tuaj yeem yaj germanium sai sai hauv huab cua. Germanium tsis cuam tshuam nrog carbon, yog li nws yog melted nyob rau hauv ib tug graphite crucible thiab yuav tsis kis los ntawm carbon. Germanium muaj cov khoom siv hluav taws xob zoo, xws li kev txav hluav taws xob, qhov txav mus los, thiab lwm yam. Txoj kev loj hlob ntawm germanium tseem muaj peev xwm zoo.
Germanium wafer tuaj yeem muab faib ua plaub pawg: Ionic germanium wafer, covalent germanium wafer, molecular germanium wafer thiab hlau germanium wafer. Txhua hom siv lead ua muaj cov khoom tshwj xeeb thiab kev siv.
Ionic germanium wafer yog tsim los ntawm qhov zoo thiab tsis zoo ions ua ke los ntawm ionic bonds. Covalent germanium wafer yog tsim los ntawm cov atoms txuas nrog covalent bonds thiab feem ntau muaj zog dua thiab melting point. Molecular germanium wafer yog tswj los ntawm cov rog intermolecular, thiab lawv cov khoom nyob ntawm kev sib cuam tshuam ntau dua. Hlau germanium wafer yog ua los ntawm cov hlau atoms sib txuas los ntawm cov ntawv cog lus hlau thiab muaj cov khoom xws li hluav taws xob thiab thermal conductivity.
Germanium germanium wafer yog covalent germanium wafer. Qhov no yog vim germanium atoms txuas nrog covalent daim ntawv cog lus los tsim cov qauv siv lead ua ruaj khov. Txhua germanium atom nyob rau hauv ib tug germanium siv lead ua sib koom ib tug electron khub nrog cov nyob sib ze germanium atoms, tsim ib tug peb-dimensional covalent network. Lub zog thiab ruaj khov ntawm daim ntawv cog lus no muab germanium germanium wafer siab hardness, melting point, thiab boiling point. Covalent daim ntawv cog lus ntawm germanium siv lead ua kuj muab qee qhov tshwj xeeb hluav taws xob. Txawm hais tias germanium thiab silicon ob leeg koom nrog plaub pawg tseem ceeb, germanium cov khoom siv hluav taws xob sib txawv ntawm silicon.
Ntxiv nrog rau covalent germanium wafer, germanium kuj tuaj yeem tsim lwm hom siv lead ua, xws li molecular germanium wafer. Tab sis qhov no yuav tsum muaj cov xwm txheej tshwj xeeb, xws li kev kub siab lossis kub, qhov twg germanium tuaj yeem tsim molecular germanium wafer uas txawv ntawm nws cov qauv siv lead ua covalent ib txwm.
Germanium Wafer Extraction txheej txheem
Kev nplua nuj
Txhim kho thiab rov ua kom rov zoo: Thawj kauj ruam hauv kev tsim cov germanium wafer yog kom rov ua kom zoo dua ntawm germanium wafer los ntawm cov txheej txheem smelting ntawm cov hlau tsis muaj hlau hnyav.
Yog tias qib ntawm cov khoom siv raw tsis siab, txhawm rau kom txuag tau tus nqi, tam sim no cov txheej txheem ua kom zoo dua qub feem ntau yog siv hauv Suav teb. Cov neeg siv cov thee los tsim cov germanium wafer feem ntau siv cov thee los tsim hluav taws xob, rov qab lub hnab plua plav thiab cov plua plav cua daj cua dub, thiab tom qab ntawd ntxiv kom tau txais cov qib uas xav tau.
Hauv cov txheej txheem hydrometallurgical zinc smelting, yog tias cov ntsiab lus germanium wafer hauv zinc mloog tsis siab, feem ntau ntawm germanium wafer yog nyob rau hauv sulfuric acid leaching residue, thiab ib feem me me ntawm germanium wafer nkag mus rau hauv cov tshuaj. Thaum lub sij hawm purification txheej txheem ntawm zinc tov, vim cov hlau-philic xwm ntawm germanium wafer, cov hlau hydroxide adsorbs germanium wafer thaum nws los nag, thiab germanium wafer nkag mus rau hauv hlau slag. Thaum zinc hmoov siv los hloov cadmium hauv cov tshuaj zinc, qhov seem ntawm germanium wafer thiab cadmium yog hloov los ntawm zinc hmoov tib lub sijhawm.
Distillation
Distillation siv qhov qis qis ntawm germanium wafer tetrachloride, txog 84 degrees Celsius, kom distilled tawm germanium wafer kom ua tiav cov nyhuv sib cais.
Distillation
Germanium wafer tetrachloride yog siv los tshem tawm lub ntsiab impurity arsenic los ntawm hydrochloric acid solvent extraction, uas yog hu ua redistillation. Tom qab ntawd nws yog purified los ntawm quartz ntauwd distillation kom tau txais high-purity germanium wafer tetrachloride. Siv cov dej purity siab kom hydrolyze germanium wafer tetrachloride kom tau txais high-purity germanium wafer dioxide (GeO2). Qee qhov impurities yuav nkag mus rau hauv cov dej cawv niam hydrolysis, yog li cov txheej txheem hydrolysis kuj yog txheej txheem purification. Lub germanium wafer hauv hydrolysis niam cawv tuaj yeem xa rov qab rau hydrochloric acid distillation.
Rov qab los
Ntshiab germanium wafer dioxide yog qhuav thiab calcined, thiab ces txo nrog hydrogen ntawm 650 mus rau 680 degree nyob rau hauv lub quartz raj ntawm qhov txo qhov cub kom tau metallic germanium wafer. Thaum kawg ntawm qhov txo qis, qhov ntsuas kub tuaj yeem maj mam nce mus rau 1000-1100 degree kom yaj cov germanium wafer, thiab maj mam txias kom tau germanium wafer ingots. Lub sijhawm txo qis feem ntau yog 24 teev, uas yog qhov ntev, nkim sij hawm thiab siv hluav taws xob ntau. Hauv kev teb rau qhov tshwm sim saum toj no, lub tshuab hluav taws xob txo qis tau tsim nyob rau hauv Suav teb, uas tam sim no siv hauv Nanjing germanium wafer Hoobkas thiab Chihong Zinc thiab germanium wafer.
