Amathuba okusetyenziswa kwezikhephe ze-silicon carbide wafer kwibala le-semiconductor

Kwintsimi ye-semiconductor, ukukhethwa kwezinto eziphathekayo kubalulekile ekusebenzeni kwesixhobo kunye nophuhliso lwenkqubo.Kule minyaka yangoku,amaqhekeza e-silicon carbide, njengezinto ezivelayo, ziye zatsala ingqalelo ngokubanzi kwaye zibonise amandla amakhulu okusetyenziswa kwintsimi ye-semiconductor.

Isikhephe seSilicon carbideyimathiriyeli yeshiti elibhityileyo elikhule kwisilicon carbide (SiC) ikristale enye.Xa kuthelekiswa nezinye izixhobo eziqhelekileyo zesemiconductor,izikhephe ze-silicon carbide waferzineengenelo ezininzi ezizodwa.Okokuqala, inomsantsa obanzi webhendi yamandla, inika ukusebenza okugqwesileyo kubushushu obuphezulu kunye nezicelo ezinamandla kakhulu.Izikhephe zeSilicon carbideinokumelana nokufuduka kwe-electron kunye nokugxininiswa komthwali kwiindawo eziphezulu zokushisa, ngaloo ndlela ibonisa ukulahleka kwamandla aphantsi kunye nokusebenza okuphezulu kwi-high-frequency, high-temperature kunye ne-high-voltage applications.

Okwesibini,izikhephe ze-silicon carbide waferube ne-thermal conductivity egqwesileyo kunye nokuzinza kwe-thermal.Oku kwenza kube yinto efanelekileyo yesiseko sezixhobo eziphezulu ze-semiconductor, ezinokuthi ziqhube ngokufanelekileyo kwaye zichithe ukushisa, ukuphucula ukuthembeka kunye nokuzinza kwesixhobo.Izikhephe zeSilicon carbidenazo zineempawu ezintle zoomatshini kunye nokuzinza kweekhemikhali, zinokuxhathisa uxinzelelo kunye nokubola kokusingqongileyo, kunye nokwandisa ubomi benkonzo yesixhobo.

Ukwengeza,izikhephe ze-silicon carbide wafernazo zineempawu ezibalaseleyo zombane.Inokunyakaza okuphezulu kwe-electron kunye nokugxininiswa kwe-carrier carrier, eyenza isantya sokutshintsha ngokukhawuleza kunye nokumelana okuphantsi.Oku kwenza i-silicon carbide wafers ibe lolona khetho lufanelekileyo kwizixhobo zamandla ezisebenza rhoqo kunye nezixhobo zombane ezinesantya esiphezulu, ezikhuthaza uphuhliso lwetekhnoloji ye-semiconductor.

Ngokuqhubela phambili okuqhubekayo kwetekhnoloji ye-semiconductor kunye nemfuno ekhulayo yamandla aphezulu, ubushushu obuphezulu, i-high-frequency kunye ne-high-speed applications, amathuba okusebenzaamaqhekeza e-silicon carbideziye zaba banzi.Inokusetyenziswa kwiinkalo ezahlukeneyo, kubandakanywa i-electronics, unxibelelwano olungenazingcingo, izithuthi zombane, i-aerospace, njl. ukuthembeka kwenkqubo.Kwintsimi yonxibelelwano olungenazingcingo, ii-silicon carbide wafers zinokusetyenziswa kumacandelo aphambili anje nge-high-frequency power amplifiers kunye nokutshintsha kwerediyo ukuze kuphunyezwe ngokukhawuleza nangokuzinza ngakumbi ukuhanjiswa kwedatha.

Isishwankathelo, izikhephe ze-silicon carbide wafer, njengezinto ezivelayo, zibonise amathemba osetyenziso olubanzi kwibala le-semiconductor.Iimpawu zayo ezibalaseleyo zombane, i-thermal kunye ne-mechanical zenza ukuba ibe yinto efanelekileyo kumandla aphezulu, ubushushu obuphezulu, i-frequency ephezulu kunye nezicelo zesantya esiphezulu.Njengoko iimfuno zokusebenza kakuhle kwamandla kunye nokusebenza ziqhubeka zisanda, ii-silicon carbide wafers kulindeleke ukuba zidlale indima ebaluleke kakhulu kwishishini le-semiconductor kwaye zikhuthaze uphuhliso olutsha lwetekhnoloji ye-semiconductor.
