Amathemba okusetshenziswa kwezikebhe ze-silicon carbide wafer emkhakheni we-semiconductor

Emkhakheni we-semiconductor, ukukhethwa kwempahla kubalulekile ekusebenzeni kwedivayisi nasekuthuthukisweni kwenqubo.Eminyakeni yakamuva,ama-wafers e-silicon carbide, njengezinto ezivelayo, zidonse ukunaka okusabalele futhi zibonise amandla amakhulu okusetshenziswa emkhakheni we-semiconductor.

Isikebhe se-silicon carbide waferimpahla yeshidi elincanyana elikhule lisuka ku-silicon carbide (SiC) ikristalu eyodwa.Uma kuqhathaniswa nezinye izinto ezijwayelekile ze-semiconductor,izikebhe ze-silicon carbide waferzinezinzuzo eziningi eziyingqayizivele.Okokuqala, inegebe elibanzi lebhendi yamandla, ikunikeza ukusebenza okuhle kakhulu kumazinga okushisa aphezulu namandla aphezulu.Izikebhe ze-silicon carbide waferingamelana nokufuduka kwama-electron kanye nokugxila kwenkampani yenethiwekhi ezindaweni ezinezinga lokushisa eliphezulu, ngaleyo ndlela ibonise ukulahlekelwa kwamandla aphansi nokusebenza kahle okuphezulu kuma-high-frequency, izinga lokushisa eliphezulu kanye nezinhlelo zokusebenza zamandla kagesi aphezulu.

Okwesibili,izikebhe ze-silicon carbide waferibe ne-thermal conductivity enhle kakhulu kanye nokuzinza kwe-thermal.Lokhu kuyenza ibe yisisekelo esikahle samadivayisi anamandla aphezulu we-semiconductor, angakwazi ukuqhuba kahle futhi akhiphe ukushisa, athuthukise ukwethembeka nokuzinza kwedivayisi.Izikebhe ze-silicon carbide waferfuthi ibe nezakhiwo ezinhle zemishini nokuzinza kwamakhemikhali, ingamelana nengcindezi kanye nokugqwala kwemvelo, futhi yandise impilo yesevisi yedivayisi.

Ngaphezu kwalokho,izikebhe ze-silicon carbide waferfuthi abe nezindawo ezinhle kakhulu zikagesi.Inokunyakaza kwama-electron aphezulu kanye nokugxila kwenkampani yenethiwekhi okuphansi, okuvumela isivinini sokushintsha ngokushesha kanye nokumelana okuphansi.Lokhu kwenza ama-wafers e-silicon carbide abe yinketho efanelekile kumadivayisi anamandla avela imvamisa ephezulu kanye nemishini kagesi enesivinini esikhulu, ekhuthaza ukuthuthukiswa kobuchwepheshe be-semiconductor.

Ngokuthuthuka okuqhubekayo kobuchwepheshe be-semiconductor kanye nesidingo esikhulayo samandla aphezulu, izinga lokushisa eliphezulu, i-high-frequency ne-high-speed applications, amathuba okufaka isiceloama-wafers e-silicon carbideziye zaba banzi.Ingasetshenziswa emikhakheni ehlukahlukene, okuhlanganisa amandla kagesi, ukuxhumana okungenantambo, izimoto zikagesi, i-aerospace, njll. Isibonelo, emkhakheni we-electronics yamandla, ama-wafers e-silicon carbide angasetshenziswa ukwenza amadivaysi okushintsha amandla asebenzayo ukuze kuthuthukiswe ukusebenza kahle kokuguqulwa kwamandla kanye ukwethembeka kwesistimu.Emkhakheni wezokuxhumana okungenantambo, amawafa e-silicon carbide angasetshenziswa ezingxenyeni ezibalulekile ezifana nezikhulisamandla zemvamisa ephezulu kanye nokushintshwa kwamafrikhwensi omsakazo ukuze kuzuzwe ukudluliswa kwedatha okushesha futhi kuzinzile.

Kafushane, izikebhe ze-silicon carbide wafer, njengezinto ezivelayo, zibonise amathemba okusebenza abanzi emkhakheni we-semiconductor.Izakhiwo zayo ezinhle kakhulu zikagesi, ezishisayo nezemishini ziyenza ibe yimpahla efanelekile yamandla aphezulu, izinga lokushisa eliphezulu, imvamisa ephezulu kanye nezicelo zejubane eliphezulu.Njengoba izidingo zokusebenza kahle kwamandla nokusebenza ziqhubeka nokwanda, ama-wafers e-silicon carbide kulindeleke ukuthi adlale indima ebaluleke kakhulu embonini ye-semiconductor futhi akhuthaze ukuthuthukiswa kobuchwepheshe be-semiconductor.
