SIC - Silicon Carbide

Silicon Carbide yakawanikwa muna 1893 sezvo maindasitiri abatsrall yekukwevera mavhiri uye emahara mabhureki. Achida pakati pezana ramakore rechi20, inoshandisa Sic Wer Wery isingashandisirwa muTse tekinoroji. Kubva ipapo, yakawedzera mune yakawanda semiconductor application nekuda kwezvinhu zvayo zvakanaka zvemuviri. Izvi zvivakwa zviri pachena mune ayo akasiyana siyana ekushandisa mukati uye kunze kweiyo Semiconductor Indasitiri. Nemutemo waMoore uchiona kusvika muganho, makambani mazhinji mukati meiyo Semiconductor Indasitiri iri kutarisa yakananga kune silicon carbides seiyo Semiconductor zvinyorwa zvenguva yemberi. SIC inogona kugadzirwa uchishandisa yakawanda polytypes yeSic, kunyangwe mukati meiyo Sicmonductor Indasitiri, inonyanya kujekesa ndeye 4h-sic, ine 6h- ichishoma yakajairika samisika yeSIC yakura. Paunenge uchireva 4h- uye 6hicon carbide, iyo H inomiririra chimiro chekristaro lattice. Nhamba yacho inomiririra kuteedzera kutevedzana kwemaatomu mukati mechinyorwa chechinyorwa, izvi zvinotsanangurwa mune svm capability chati pazasi. Zvakanakira Silicon Carbide Hardness pane zvakawanda zvakanakira kushandisa silicon carbide pamusoro pezvimwe zviyo silicon substrates. Chimwe chezvakanakisa zvakanakira zvezvinhu izvi ndiko kuomesa kwayo. Izvi zvinopa zviwanikwa zvakawanda zvakawanda, mukumhanya kwakanyanya, tembiricha yakakwira uye / kana yakanyanya voltage application. Silicon Carbide Wafers ane Yakanyanya Kudza Docery, zvinoreva kuti vanogona kuendesa kupisa kubva pane imwe nguva kuenda kune imwe tsime. Izvi zvinovandudza magetsi aro nemagetsi uye pakupedzisira miniaturization, chimwe chezvimwe zvinangwa zvekuchinja kune sic wical. Kubata Kwake Kugona kweSIC Siki kune zvakare kuderera kwehuwandu hwekuwedzera kwekuwedzera. Kuwedzera kwekuwedzera huwandu uye kutungamira zvinhu zvinowedzera kana zvibvumirano sezvazvinosimudza kana kutonhora pasi. Tsananguro yakajairika ndeyechando, kunyangwe ichiita zvinopesana nesimbi zhinji, ichiwedzera sezvo ichitonhorera nekudzikira sezvo ichipfuura. Silicon carbide's yakaderera coefficiden yekuwedzera nzira zvinoreva kuti hazvishanduke zvakanyanya muhukuru kana kuiswa pasi, izvo zvinoita kuti zviite zvakaringana nemidziyo madiki uye kurongedza vatengesi zvakanyanya pane chimwe chipituritwe. Chimwe mukana mukuru weaya substrates ndiko kurwisa kwavo kwakanyanya kuuraya kushamisika. Izvi zvinoreva kuti ivo vane kugona kuchinja tembiricha nekukurumidza vasina kupwanya kana kupaza. Izvi zvinogadzira mukana wakajeka kana uchiita shanduko sezvo imwe nzira yakaoma iyo inovandudza hupenyu uye kuita kweiyo silicon carbide mukuenzanisa neyakawandisa bulk silicon. Pamusoro pekugona kwayo kwekunyora, iyo substrate yakasimba kwazvo uye haina kuita neacids, alkalis kana yakanyungudutswa munyu pamusoro pekushomeka kusvika 800 ° C. Izvi zvinopa izvi zveshuwa zvinowanzanisa mune zvavanonyorera uye zvimwe zvinobatsira kugona kwavo kunze kwechiitiko chombo mune akawanda mashandisirwo. Simba rayo rekupisa kwakanyanya zvakare rinobvumirawo kuti zviitwe nekuchengeteka pakupisa kwevanopfuura 1600 ° C. Izvi zvinoita kuti ive yakakodzera substrate yeinenge chero yakanyanya kupisa tembiricha.
