Sephaphatha sa semiconductor ke eng?
Sephaphatha sa semiconductor ke selae se tšesaane, se chitja sa thepa ea semiconductor e sebetsang e le motheo oa ho etsoa ha li-circuits (ICs) le lisebelisoa tse ling tsa elektroniki. Sephaphatha se fana ka sebaka se bataletseng le se ts'oanang moo likarolo tse fapaneng tsa elektronike li hahiloeng holim'a tsona.
Ts'ebetso ea ho etsa li-wafer e kenyelletsa mehato e mengata, ho kenyelletsa le ho holisa kristale e le 'ngoe e kholo ea thepa e lakatsehang ea semiconductor, ho seha kristale hore e be liphaphatha tse tšesaane ho sebelisa sakha ea daemane, ebe o bentša le ho hloekisa liphaphatha ho tlosa likoli kapa litšila. Li-wafers tse hlahisoang li na le bokaholimo bo bataletseng le bo boreleli, e leng ntho ea bohlokoa bakeng sa lits'ebetso tse latelang tsa masela.
Hang ha li-wafers li se li lokisitsoe, li kena letotong la mekhoa ea ho etsa li-semiconductor, tse kang photolithography, etching, deposition, le doping, ho etsa mekhoa e rarahaneng le likarolo tse hlokahalang ho haha lisebelisoa tsa elektroniki. Mekhoa ena e phetoa ka makhetlo a mangata holim'a lesela le le leng ho etsa lipotoloho tse ngata tse kopantsoeng kapa lisebelisoa tse ling.
Kamora hore ts'ebetso ea boqapi e phetheloe, li-chips ka bomong li aroloa ka ho rala sephaphatha ka mela e boletsoeng esale pele. Li-chips tse arohaneng li ntan'o pakoa ho li sireletsa le ho fana ka likhokahano tsa motlakase bakeng sa ho kopanngoa le lisebelisoa tsa elektroniki.
Lisebelisoa tse fapaneng holim'a wafer
Li-wafers tsa semiconductor li entsoe haholo ka silicon ea kristale e le 'ngoe ka lebaka la bongata ba eona, thepa e ntle ea motlakase, le ho lumellana le mekhoa e tloaelehileng ea tlhahiso ea semiconductor. Leha ho le joalo, ho ipapisitse le lits'ebetso le litlhoko tse ikhethileng, lisebelisoa tse ling le tsona li ka sebelisoa ho etsa li-wafers. Mehlala ke ena:
Silicon carbide (SiC) ke thepa e pharalletseng ea semiconductor e fanang ka thepa ea boleng bo holimo ha e bapisoa le thepa ea setso. E thusa ho fokotsa boholo le boima ba lisebelisoa tsa discrete, li-module, esita le litsamaiso tsohle, ha li ntse li ntlafatsa ts'ebetso.
Litšobotsi tsa bohlokoa tsa SiC:
- - Bandgap e pharaletseng:SiC's bandgap e ka ba makhetlo a mararo ho feta ea silicon, e lumellang hore e sebetse ka mocheso o phahameng, ho fihlela ho 400 ° C.
- - Sebaka se phahameng sa Karohano ea Bohlokoa:SiC e khona ho mamella ho fihla ho makhetlo a leshome sebaka sa motlakase sa silicon, e leng se etsang hore e be se loketseng bakeng sa lisebelisoa tse phahameng tsa motlakase.
- - High Thermal Conductivity:SiC e tlosa mocheso hantle, e thusa lisebelisoa ho boloka mocheso o nepahetseng oa ts'ebetso le ho lelefatsa bophelo ba tsona.
- -Lebelo le Phahameng la Elektrone Drift:Ka lebelo la ho hoholeha la silicon habeli, SiC e thusa maqhubu a phahameng a ho fetoha, e thusang ho miniaturization ea sesebelisoa.
Lisebelisoa:
-
- Matla a elektroniki:Lisebelisoa tsa motlakase tsa SiC li ipabola libakeng tse nang le motlakase o mongata, oa morao-rao, mocheso o phahameng, le maemo a phahameng, e leng ho matlafatsang matla a ho fetola matla haholo. Li sebelisoa haholo likoloing tsa motlakase, liteishene tsa ho tjhaja, sistimi ea photovoltaic, lipalangoang tsa literene le marang-rang a bohlale.
-
-Microwave Communications:Lisebelisoa tsa GaN RF tse thehiloeng ho SiC li bohlokoa bakeng sa lisebelisoa tsa puisano tse se nang mohala, haholo-holo bakeng sa liteishene tsa motheo tsa 5G. Lisebelisoa tsena li kopanya ts'ebetso e ntle ea mocheso oa SiC le tlhahiso ea RF e phahameng ea GaN, e nang le matla a phahameng, e leng se etsang hore e be khetho e ratoang bakeng sa marang-rang a marang-rang a phahameng a maqhubu a phahameng.
Gallium nitride (GaN)ke moloko oa boraro o pharaletseng oa lisebelisoa tsa semiconductor tse nang le bandgap e kholo, conductivity e phahameng ea mocheso, lebelo le phahameng la elektronike saturation drift, le litšobotsi tse babatsehang tsa tšimo. Lisebelisoa tsa GaN li na le tebello e pharaletseng ea ts'ebeliso libakeng tse nang le maqhubu a phahameng, lebelo le phahameng le matla a phahameng joalo ka mabone a bolokang matla a LED, lipontšo tsa laser projection, likoloi tsa motlakase, marang-rang a bohlale, le likhokahano tsa 5G.
Gallium arsenide (GaAs)ke thepa ea semiconductor e tsejoang ka maqhubu a eona a phahameng, ho tsamaea ha elektronike e phahameng, matla a phahameng a matla, lerata le tlaase, le linearity e ntle. E sebelisoa haholo indastering ea optoelectronics le microelectronics. Ho optoelectronics, li-substrates tsa GaAs li sebelisetsoa ho etsa LED (light-emitting diodes), LD (laser diodes), le lisebelisoa tsa photovoltaic. Ho li-microelectronics, ba hiriloe ho hlahisa li-MESFET (metal-semiconductor field-effect transistors), HEMTs (high electron mobility transistors), HBTs (heterojunction bipolar transistors), ICs (integrated circuits), microwave diode, le lisebelisoa tsa Hall effect.
Indium phosphide (InP)ke e 'ngoe ea li-semiconductors tsa bohlokoa tsa III-V, tse tsejoang ka ho tsamaea ha elektronike e phahameng, ho hanyetsa mahlaseli a mangata, le lekhalo le pharaletseng. E sebelisoa haholo indastering ea optoelectronics le microelectronics.
