I-Rigid Graphite Felt

I-Semixlab Rigid Graphite Felt (RGF) iklanywe njengento ebaluleke kakhulu yokufaka izinga lokushisa eliphezulu kanye nengxenye yokulawula okushisayo ekukhuleni kwe-Physical Vapor Transport (PVT) yamakristalu e-SiC eyodwa. Idizayinelwe ukusetshenziswa esizukulwaneni esilandelayo sokukhiqizwa kwe-wafer ye-4H- kanye ne-6H-SiC, lokhu kuzwakala okuqinile kuhlanganisa ukuqhutshwa kwe-ultra-low thermal, ubuqotho obuphezulu besakhiwo, nokuhlanzeka kwamakhemikhali okuyingqayizivele, okuyenza ibe yitshe legumbi eziko ezisebenza kahle kakhulu ze-SiC sublimation. Ukusetshenziswa kwayo kuqinisekisa ukulawula okunembile kwamagradient ashisayo, izimo zokukhula ezizinzile, kanye nekhwalithi yekristalu ethuthukisiwe kuyo yonke imijikelezo yokukhiqiza yesikhathi eside.

Enqubweni ye-SiC PVT, ukugcina inkambu eshisayo engaguquki futhi efanayo kubalulekile ekuzuzeni amakristalu angawodwa angenasici. I-Graphite Rigid Felt isebenza njengento eyinhloko yokufaka isithando somlilo, ezungeze i-sublimation crucible kanye nezakhiwo zensimu eshisayo. I-thermal conductivity yayo ephansi inciphisa ukulahlekelwa ukushisa okungafunwa, igcina izinga lokushisa eliqondiwe phakathi komthombo we-SiC nekristalu lembewu. Ngokulawula amaphrofayli okushisa e-radial kanye ne-axial, i-RGF inciphisa ukwakheka kokugudluka kwendiza eyisisekelo, amaphutha ekustaki, namapayipi amancane, okuthinta ngokuqondile ubuqotho besakhiwo nokusebenza kwe-elekthronikhi kwamawafa e-SiC angumphumela.

Ngaphandle kwamakhono ayo okufaka ukufudumala okushisayo, ukwakheka okuqinile kwe-graphite ye-Semixlab's graphite kunikeza ukuzinza kwemishini ezindaweni ezishisa kakhulu ezidlula u-2000°C. Ngokungafani nezinsimbi ezithambile noma ezithambile, i-RGF igcina isimo sayo ngaphansi kokuhamba ngebhayisikili okushisayo isikhathi eside, ivimbela ukuwohloka noma ukuwohloka okungase kuphazamise inkambu yokushisa noma konakalise impilo yonke yesithando somlilo. I-inertness yayo yamakhemikhali iqinisekisa ukukhishwa okuncane kwezinhlayiya futhi igwema ukungcoliswa kwe-SiC boule, okubalulekile ekukhiqizeni ama-substrates amelana kakhulu nama-electronics amandla nezinhlelo zokusebenza zedivayisi ye-wide-bandgap.

Ikhiqizwe kusetshenziswa i-high-purity graphitic carbon nezindlela zokuminyana ezithuthukile, i-Semixlab Graphite Rigid Felt ibonisa ukuminyana okufanayo, ukuzinza kwe-dimensional okuhle kakhulu, nokuqina kwesikhathi eside. Ukuhlanganiswa kwayo kokusebenza okushisayo kanye nokuqina kwemishini kwenza izindwangu ze-semiconductor zifinyelele amazinga okukhula angaguquki, amaphrofayili okushisa akhiqizwayo, kanye nokunciphisa isikhathi sokuphumula ezinhlelweni ze-PVT. Ngokuthuthukisa ukusebenza kahle kokushisa kwesithando somlilo, i-RGF iphinde ibe negalelo ekongeni amandla kuyilapho ithuthukisa ukufana kwe-wafer kanye nesivuno.

I-Semixlab's Rigid Graphite Felt inikezela ngokusebenza, ukuhlanzeka, nokuzinza kwesakhiwo okudingekayo ukusekela ukukhula kwekristalu eyodwa ye-SiC, ihlinzeka abakhiqizi ngesixazululo esiqinile sezinto ezibonakalayo zokukhiqizwa kwewafer yesizukulwane esilandelayo, impilo yesithando enwetshiwe, nokuphathwa okushisayo okuphakeme ezindaweni ezishisa kakhulu.
