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 waferbabe 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 ibe 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 yinto 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.
