Semiconductor Quartz: Karolo ea Bohlokoa ho Elektronike ea Kajeno
Kenyelletso ea Lisebelisoa tsa Quartz
Quartz (SiO₂) e ka 'na ea tšoana le khalase ha u habanya feela, empa thepa ea eona e ikhethang e e khetholla. Ho fapana le khalase e tloaelehileng, e nang le likarolo tse ngata (tse kang lehlabathe la quartz, borax, barium carbonate, limestone, feldspar le soda), quartz e entsoe feela ka SiO₂. Sena se e fa sebopeho se bonolo sa marang-rang se entsoeng ke likarolo tsa tetrahedral tsa silicon dioxide.
Bohlokoa ba Quartz ea Bohloeki bo Phahameng
Quartz e phahameng, eo hangata e bitsoang "moqhaka" oa thepa ea khalase, e fana ka thepa e ikhethang ka lebaka la litšila tse fokolang tsa tšepe. Boitsebiso bona bo tsotehang bo bohlokoa lits'ebetsong tse fapaneng tsa semiconductor, ho ithorisa ka melemo e kang:
1. Ho hanyetsa Mocheso o Phahameng: Ka ntlha e fokolang ea hoo e ka bang 1730 ° C, quartz e ka mamella tšebeliso ea nako e telele ho 1150 ° C le ho sebetsana le ho phatloha ho khutšoanyane ho fihlela ho 1450 ° C.
2. Lik'hemik'hale tsa Corrosion Resistance: Quartz e hloekileng e phahameng e bonts'a reactivity e fokolang ka li-acids tse ngata (ntle le hydrofluoric acid) 'me e bontša botsitso bo phahameng khahlanong le tlhaselo ea lik'hemik'hale, e leng makhetlo a 30 a hanyetsanang le asiti ho feta li-ceramics le makhetlo a 150 a hanyetsang ho feta tšepe e sa hloekang.
3. Thermal Stability: High-purity quartz e na le coefficient e tlase haholo ea ho atolosa mocheso, e lumellang ho mamella liphetoho tse potlakileng tsa mocheso ntle le ho robeha.
4. Optical Clarity: Thepa ena e boloka phetiso e phahameng ho pholletsa le mefuta e mengata, e nang le khanya e bonahalang e fetang 93% le ultraviolet transmittance e fihlang ka holimo ho 80%.
5. Insulation ea Motlakase: Quartz e hloekileng e fana ka khanyetso e ikhethang ea motlakase, e etsang hore e be insulator e babatsehang esita le mocheso o phahameng.
Likopo ho Indasteri ea Semiconductor
Ka lebaka la thepa ena e ikhethang ea 'mele le ea lik'hemik'hale, quartz e hloekileng e sebelisoa haholo ho lisebelisoa tsa sejoale-joale tsa elektroniki, likhokahano tsa mehala le indastering ea semiconductor. Tlhokahalo e ntseng e hola ea li-wafers tsa silicon e ekelitse tlhoko ea likarolo tsa quartz haholo, haholo tlhahisong ea li-chip.
Lisebelisoa tsa bohlokoa tsa Quartz ho Semiconductor Manufacturing:
1. Lisebelisoa tsa Mocheso o Phahameng:
· Li-Tubes tsa Quartz Furnace:E bohlokoa bakeng sa lits'ebetso tse kang phallo, oxidation, le annealing, li-tubes tsena li netefatsa botsitso ba mocheso o phahameng le ho sebetsa hantle nakong ea tlhahiso ea semiconductor.
·Likepe tsa Quartz:E sebelisetsoa ho tsamaisa le ho sebetsana le li-wafers tsa silicon, liketsoana tsa quartz li thusa ho etsa li-batch mekhoeng ea ho hasana.
2. Lisebelisoa tsa Mocheso o Tlase:
Mehele ea Quartz:E kenyelelitsoe ts'ebetsong ea etching, mehele ea quartz e thibela tšilafalo le ho netefatsa tlhahiso e nepahetseng nakong ea lithography le patterning.
· Libaskete le Litanka tsa ho Hloekisa Quartz:Likarolo tsena ke tsa bohlokoa bakeng sa ho hloekisa liphaephe tsa silicon. Ba tlameha ho hanela asiti le alkali ha ba ntse ba fokotsa sebaka sa ho ikopanya ho ntlafatsa ts'ebetso ea ho hloekisa.
Qetello
Le ha likarolo tsa quartz li ka hlaha e le lisebelisoa tse nyane ts'ebetsong ea tlhahiso ea semiconductor, li bapala karolo ea bohlokoa ho netefatsa boleng le ts'epahalo ea lisebelisoa tsa semiconductor. Ho latela Techcet, lisebelisoa tsa khalase tsa quartz tse hloekileng haholo li etsa hoo e ka bang 90% ea tlhahiso ea selemo le selemo ea indasteri ea tlhahisoleseling ea elektroniki.
Ho Semicera, re ikemiselitse ho ntšetsa pele indasteri ea semiconductor ka ho fana ka lisebelisoa tsa quartz tse sebetsang hantle. Joalo ka ha lipekere li le bohlokoa bakeng sa botsitso ba sebopeho, ho joalo le ka quartz bakeng sa tlhahiso ea semiconductor.
2. Lisebelisoa tsa Mocheso o Tlase:
·Mehele ea Quartz: E kenyelelitsoe ts'ebetsong ea etching, mehele ea quartz e thibela tšilafalo le ho netefatsa tlhahiso e nepahetseng nakong ea lithography le patterning.
·Libaskete le Litanka tsa ho Hloekisa Quartz: Likarolo tsena li bohlokoa bakeng sa ho hloekisa liphaephe tsa silicon. Ba tlameha ho hanela asiti le alkali ha ba ntse ba fokotsa sebaka sa ho ikopanya ho ntlafatsa ts'ebetso ea ho hloekisa.
Qetello
Le ha likarolo tsa quartz li ka hlaha e le lisebelisoa tse nyane ts'ebetsong ea tlhahiso ea semiconductor, li bapala karolo ea bohlokoa ho netefatsa boleng le ts'epahalo ea lisebelisoa tsa semiconductor. Ho latela Techcet, lisebelisoa tsa khalase tsa quartz tse hloekileng haholo li etsa hoo e ka bang 90% ea tlhahiso ea selemo le selemo ea indasteri ea tlhahisoleseling ea elektroniki.
Ho Semicera, re ikemiselitse ho ntšetsa pele indasteri ea semiconductor ka ho fana ka lisebelisoa tsa quartz tse sebetsang hantle. Joalo ka ha lipekere li le bohlokoa bakeng sa botsitso ba sebopeho, ho joalo le ka quartz bakeng sa tlhahiso ea semiconductor.
