Makhalidwe Atsopano M'makampani a Semiconductor: Kugwiritsa Ntchito Tekinoloje Yachitetezo Chophimba

Makampani a semiconductor akuchitira umboni kukula komwe sikunachitikepo, makamaka m'malo asilicon carbide (SiC)zamagetsi zamagetsi. Ndi zambiri zazikulumtandaNsalu zomwe zikumangidwa kapena kukulitsidwa kuti zikwaniritse kufunikira kokulirapo kwa zida za SiC pamagalimoto amagetsi, boom iyi imapereka mwayi wopeza phindu. Komabe, imabweretsanso zovuta zapadera zomwe zimafuna mayankho anzeru.

Pamtima pakuchulukirachulukira kwapadziko lonse lapansi kupanga chip cha SiC ndiko kupanga makhiristo apamwamba a SiC, zowotcha, ndi zigawo za epitaxial. Pano,Semiconductor-grade graphiteZida zimagwira ntchito yofunika kwambiri, kuthandizira kukula kwa kristalo wa SiC ndikuyika kwa zigawo za SiC epitaxial. Kusungunula kwamafuta a graphite ndi kusakhazikika kumapangitsa kuti ikhale chinthu chokondedwa, chomwe chimagwiritsidwa ntchito kwambiri mu crucibles, pedestals, mapulaneti disks, ndi ma satellites mkati mwa kukula kwa crystal ndi epitaxy systems. Komabe, zovuta zogwirira ntchito zimakhala zovuta kwambiri, zomwe zimapangitsa kuti zigawo za graphite ziwonongeke mofulumira ndipo kenako zimalepheretsa kupanga makristasi apamwamba a SiC ndi zigawo za epitaxial.

Kupanga makristalo a silicon carbide kumabweretsa zovuta kwambiri, kuphatikiza kutentha kopitilira 2000 ° C ndi zinthu zowononga kwambiri mpweya. Izi nthawi zambiri zimabweretsa dzimbiri zonse za graphite crucibles pambuyo pozungulira kangapo, potero zimakwera mtengo wopanga. Kuphatikiza apo, zovutazo zimasintha mawonekedwe apamwamba a zigawo za graphite, kusokoneza kubwereza komanso kukhazikika kwa kupanga.

Kuti athane ndi zovutazi mogwira mtima, ukadaulo wakutchingira woteteza wawonekera ngati wosintha masewera. Zotchingira zoteteza zochokeratantalum carbide (TaC)adziwitsidwa kuti athetse vuto la kuwonongeka kwa chigawo cha graphite ndi kusowa kwa graphite. Zida za TaC zimawonetsa kutentha kosungunuka kupitirira 3800 ° C ndi kukana kwapadera kwamankhwala. Kugwiritsa ntchito ukadaulo wa Chemical vapor Deposition (CVD),Zovala za TaCndi makulidwe a mamilimita 35 akhoza seamlessly waikamo pa graphite zigawo zikuluzikulu. Chotchinga chotetezachi sichimangowonjezera kukhazikika kwa zinthu komanso kumatalikitsa moyo wa zigawo za graphite, zomwe zimachepetsa mtengo wopanga ndikuwonjezera magwiridwe antchito.

Semicera, wotsogolera wamkulu waZovala za TaC, yathandiza kwambiri kusintha makampani opangira zida zamagetsi. Ndi luso lake lamakono komanso kudzipereka kosasunthika ku khalidwe labwino, Semicera yathandiza opanga ma semiconductor kuthana ndi zovuta zazikulu ndikupeza kupambana kwatsopano. Popereka zokutira za TaC ndi magwiridwe antchito osayerekezeka komanso kudalirika, Semicera yalimbitsa udindo wake ngati mnzake wodalirika wamakampani opanga ma semiconductor padziko lonse lapansi.

Pomaliza, chitetezo ❖ kuyanika luso, zoyendetsedwa ndi zatsopano ngatiZovala za TaCkuchokera ku Semicera, ikukonzanso mawonekedwe a semiconductor ndikutsegulira njira ya tsogolo labwino komanso lokhazikika.
