Sephaphatha sa kristale se le seng sa boleng bo holimo (Silicon Carbide) ho indasteri ea elektroniki le ea optoelectronic. 3inch SiC wafer ke thepa ea semiconductor ea moloko o latelang, liphaephe tse sireletsang silicon-carbide tse bophara ba lisenthimithara tse 3. Li-wafers li etselitsoe ho etsa lisebelisoa tsa motlakase, RF le optoelectronics.

Tlhaloso

3-inch 4H semi-insulated SiC (silicon carbide) substrate wafers ke lintho tse sebelisoang ka tloaelo semiconductor. 4H e bontša sebopeho sa kristale sa tetrahexahedral. Semi-insulation e bolela hore substrate e na le litšobotsi tse phahameng tsa ho hanyetsa 'me e ka ba ka thōko ho phallo ea hona joale.

Li-wafers tse joalo tsa substrate li na le litšobotsi tse latelang: conductivity e phahameng ea mocheso, tahlehelo e tlaase ea conduction, ho hanyetsa mocheso o phahameng haholo, le botsitso bo botle ba mechine le lik'hemik'hale. Hobane silicon carbide e na le lekhalo le leholo la matla 'me e khona ho mamella mocheso o phahameng le maemo a phahameng a tšimo ea motlakase, li-wafers tsa 4H-SiC tse nang le semi-insulated li sebelisoa haholo ho lisebelisoa tsa motlakase le tsa radio frequency (RF).

Lisebelisoa tsa mantlha tsa 4H-SiC semi-insulated wafers li kenyelletsa:

1--Power electronics: 4H-SiC wafers e ka sebelisoa ho etsa lisebelisoa tsa ho fetola matla tse kang MOSFETs (Metal Oxide Semiconductor Field Effect Transistors), IGBTs (Insulated Gate Bipolar Transistors) le Schottky diode. Lisebelisoa tsena li na le tahlehelo e tlase ea conduction le switching libakeng tse phahameng tsa motlakase le mocheso o phahameng mme li fana ka ts'ebetso e phahameng le ts'epahalo.

Lisebelisoa tsa 2-Radio Frequency (RF): 4H-SiC semi-insulated wafers e ka sebelisoa ho etsa matla a phahameng, li-amplifiers tse phahameng tsa RF, li-resistors tsa chip, li-filters le lisebelisoa tse ling. Silicon carbide e na le ts'ebetso e betere ea maqhubu a holimo le botsitso ba mocheso ka lebaka la sekhahla sa eona se seholo sa ho hoholeha ha elektronike le conductivity e phahameng ea mocheso.

3 - Lisebelisoa tsa Optoelectronic: 4H-SiC semi-insulated wafers e ka sebelisoa ho etsa li-laser diode tse matla, li-detectors tsa leseli tsa UV le li-circuits tse kopantsoeng tsa optoelectronic.

Mabapi le tataiso ea 'maraka, tlhoko ea li-wafers tse kentsoeng ka semi-insulated tsa 4H-SiC e ntse e eketseha ka masimo a ntseng a hola a lisebelisoa tsa elektroniki tsa motlakase, RF le optoelectronics. Sena se bakoa ke taba ea hore silicon carbide e na le mefuta e mengata ea lisebelisoa, ho kenyelletsa matla a matla, likoloi tsa motlakase, matla a tsosolositsoeng le puisano. Nakong e tlang, 'maraka oa 4H-SiC semi-insulated wafers o ntse o ts'episa haholo mme o lebelletsoe ho nkela thepa e tloaelehileng ea silicon lits'ebetsong tse fapaneng.
