Semiconductor Soft Graphite Felt

Semiconductor Soft Graphite Felt chinhu chakachena kwazvo, chinodzivirira kupisa zvakanyanya, chakagadzirirwa zvakanyanya kugadzirwa kwema semiconductor mumamiriro ekupisa kwakanyanya. Mumidziyo yepamusoro ye semiconductor, kunyanya iyo inoshandiswa pakukura kwekristalo yesilicon carbide (SiC), epitaxy, uye kurapwa kwekupisa kwakanyanya, kudzora kwakanyatsojeka kwenzvimbo yekupisa kwakakosha pakushanda kwechinhu uye mhando yezvinhu. Semixlab's Soft Graphite Felt inoshanda sechinochengetedza kupisa zvakanyanya uye zvinhu zvinosimbisa thermal field mukati memasisitimu aya anoda simba.

Mumaitiro ekukura kwekristaro imwe chete yeSiC akadai sePhysical Vapor Transport (PVT), graphite felt inoita basa rakakosha mukudzikamisa munda wekupisa wechoto. Graphite Felt inoshanda sechikamu chinodzivirira uye chinovhara chakakomberedza ma crucibles nenzvimbo dzekudziya, ichideredza kurasikirwa kwekupisa kwe radial ne axial uku ichinyorovesa tembiricha mukati mekamuri yekukura. Iyi nzvimbo yekupisa inodzorwa yakakosha pakuchengetedza kuenzana kwakasimba kwe sublimation-recrystallization, ichikanganisa zvakananga mwero wekukura kwekristaro, defect density, uye kugadzikana kwekukura kwenguva refu. Maumbirwo akapfava uye ari nyore kuumbwa eGraphite Soft Felt anogonesa kugadzirisa zvakananga kune geometries dzakaoma dzechoto, zvichiita kuti mamiriro ekupisa adzokororwe mukati menguva refu yekukura.

Pakupararira kwekupisa kwakanyanya, kunyungudutsa, uye kusvina kwakajairika mukugadzira semiconductor, semiconductor soft graphite felt inoshanda senzvimbo yakavimbika yekudzivirira kupisa, ichichengetedza hunhu hwayo pasi pekupisa kunodzokororwa. Ichishanda mumhepo ine vacuum kana inert pakupisa kunowanzo pfuura 2000 °C, Soft Insulation inoderedza kurasikirwa nekupisa kwefurnace shell, inowedzera kushanda zvakanaka kwesimba, uye inokurudzira kugoverwa kwakafanana kwekupisa mukati menzvimbo yekushanda. Kufambisa kwayo kupisa kwakaderera uye kuramba kwayo kupisa kwakanyanya kunoderedza kushushikana pamidziyo nezvinhu zvakagadzirwa, zvichiita kuti mhedzisiro ienderane uye kuwedzera hupenyu hwemidziyo.

Mumaitiro eSiC neGaN epitaxy, ma epitaxial reactors anowanzo shanda pakupisa kwakanyanya kunoda mamiriro akasimba. Graphite Soft Felt inowedzera kugadzikana kwekupisa uye kuparadzaniswa kwezvakatipoteredza mukati mezvikamu zve reactor. Sechinhu chinodzivirira mukati uye chinhu chinochengetedza kupisa, chinokurudzira kugoverwa kwekupisa kwakafanana uye chinoderedza kupindira kwekunze kwekupisa, nenzira isina kunanga inovandudza kufanana kwe epitaxial layer uye kudzokorora kwemaitiro. Kuchena kwakanyanya kweSemixlab's graphite felt kwakakosha zvikuru munzvimbo idzi, sezvo ichibatsira kuchengetedza mamiriro ekushanda akachena uye inoderedza njodzi yekusvibiswa kusingatarisirwi kunogona kukanganisa kunaka kwefirimu re epitaxial.

Semixlab's Semiconductor Soft Graphite Felt yakagadzirwa nezvinhu zvepamusoro-soro zve carbon precursor uye maitiro ekugadzira akanyatsojeka, ichibatanidza kuramba kupisa kwakanyanya, kufambisa kupisa kwakaderera, uye kuchinjika kwakanyanya kwemakanika. Izvi zvinogonesa kushanda kwakasimba kwenguva refu munzvimbo dzinoda kugadzirwa kwe semiconductor ukuwo zvichipa nyore kuisa, kugadzira, uye kubatanidzwa mumhando dzakasiyana dzemagadzirirwo evira ne reactor. Ichishandisa hunyanzvi hwaSemixlab muzvinhu zvepamusoro zve semiconductor uye mhinduro dzekupisa, chigadzirwa ichi chinoshanda sechinhu chakakosha chemaitiro e semiconductor ekupisa kwakanyanya. Panguva imwe chete, Semixlab yakazvipira kupa mazano ehunyanzvi hwehunyanzvi uye mhinduro dzezvigadzirwa dzakagadziriswa kune vatengi vepasi rese. Tinotarisira nemoyo wese kuva mubatsiri wako wenguva refu wezvinhu zvekudzivirira kupisa uye kudzikamisa munda wekupisa muindasitiri ye semiconductor yeChina.
