SiC wafers ni semiconductor ikozwe muri karubide ya silicon. Ibi bikoresho byakozwe mu 1893 kandi nibyiza mubikorwa bitandukanye. Cyane cyane kibereye kuri diode ya Schottky, inzitizi ihuza Schottky diode, guhinduranya hamwe nicyuma-oxyde-semiconductor umurima-ngaruka transistors. Bitewe no gukomera kwayo, ni amahitamo meza kubikoresho bya elegitoroniki.
Kugeza ubu, hari ubwoko bubiri bwingenzi bwa SiC wafers. Iya mbere ni wafer isukuye, ni wafer ya silicon imwe. Ikozwe muri kirisiti nziza ya SiC kandi irashobora kuba 100mm cyangwa 150mm ya diametre. Ikoreshwa mubikoresho bikomeye bya elegitoroniki. Ubwoko bwa kabiri ni epitaxial kristal silicon karbide wafer. Ubu bwoko bwa wafer bukozwe mukongeramo urwego rumwe rwa silicon karbide kristaliste hejuru. Ubu buryo busaba kugenzura neza ubunini bwibintu kandi bizwi nka N-epitaxy.
Ubwoko bukurikira ni beta silicon karbide. Beta SiC ikorerwa ku bushyuhe buri hejuru ya dogere selisiyusi 1700. Alpha karbide nizisanzwe kandi zifite imiterere ya kristu ya mpandeshatu isa na wurtzite. Ifishi ya beta isa na diyama kandi ikoreshwa mubisabwa bimwe. Iteka ryabaye ihitamo ryambere kubinyabiziga byamashanyarazi ibicuruzwa bitarangiye. Abatanga amasoko menshi ya silicon karbide wafer kuri ubu barimo gukora kuri ibi bikoresho bishya.
Wafer ya ZMSH SiC ni ibikoresho bikoreshwa cyane bya semiconductor. Nibikoresho byujuje ubuziranenge bwa semiconductor bikwiranye na progaramu nyinshi. ZMSH silicon karbide wafers nibikoresho byingirakamaro kubikoresho bitandukanye bya elegitoroniki. ZMSH itanga intera nini ya SiC wafers yo mu rwego rwo hejuru. Baraboneka muburyo bwa N-na kimwe cya kabiri.
2 --- Carbide ya Silicon: Kugana ibihe bishya bya wafer
Imiterere yumubiri nibiranga silicon karbide
Carbide ya silicon ifite imiterere yihariye ya kirisiti, ikoresheje impande esheshatu zegeranye zegeranye na diyama. Iyi miterere ituma karibide ya silicon igira ubushyuhe bwiza bwumuriro hamwe nubushyuhe bwo hejuru. Ugereranije nibikoresho bya silikoni gakondo, karbide ya silicon ifite ubugari bunini bwa bande, itanga intera ndende ya elegitoronike, bikavamo umuvuduko mwinshi wa electron hamwe nuyoboro wo hasi. Mubyongeyeho, karbide ya silicon nayo ifite umuvuduko mwinshi wa electron yuzuza umuvuduko hamwe no kurwanya ibintu bike ubwabyo, bitanga imikorere myiza kumashanyarazi menshi.
Gusaba imanza hamwe nicyizere cya silicon karbide wafers
Imbaraga za elegitoroniki
Silicon carbide wafer ifite ibyifuzo byinshi mubikorwa bya electronics. Bitewe numuvuduko mwinshi wa elegitoronike hamwe nubushuhe buhebuje bwumuriro, wafer ya SIC irashobora gukoreshwa mugukora ibikoresho byoguhindura ingufu nyinshi cyane, nka modul yamashanyarazi kubinyabiziga byamashanyarazi hamwe nizuba. Ubushyuhe bwo hejuru bwa silicon karbide wafers ituma ibyo bikoresho bikora mubushyuhe bwo hejuru, bitanga imikorere myiza kandi yizewe.
Porogaramu ya Optoelectronic
Mu rwego rwibikoresho bya optoelectronic, wafer ya silicon karbide yerekana ibyiza byihariye. Ibikoresho bya karubide ya silicon bifite intera nini ya bande, ituma igera ku mbaraga za fotonon nyinshi no gutakaza urumuri ruke mubikoresho bya optoelectronic. Wafer ya silicon karbide irashobora gukoreshwa mugutegura ibikoresho byitumanaho byihuse, fotodetekeri na laseri. Ubwiza buhebuje bwumuriro hamwe nubucucike buke bwa kirisiti ituma biba byiza mugutegura ibikoresho byiza bya optoelectronic.
Outlook
Hamwe nogukenera gukenera ibikoresho bya elegitoroniki bikora cyane, wafer ya silicon karbide ifite ejo hazaza heza nkibikoresho bifite imitungo myiza kandi ishobora gukoreshwa. Hamwe nogukomeza kunoza tekinoroji yo gutegura no kugabanya ibiciro, ikoreshwa ryubucuruzi bwa silicon karbide wafers izatezwa imbere. Biteganijwe ko mu myaka mike iri imbere, wafer ya silicon karbide izinjira buhoro buhoro ku isoko kandi ihinduka inzira nyamukuru yo gukoresha ingufu nyinshi, inshuro nyinshi hamwe nubushyuhe bwo hejuru.
3 --- Isesengura ryimbitse ryisoko rya WaC isoko niterambere ryikoranabuhanga
Isesengura ryimbitse rya silicon karbide (SiC) wafer isoko
Iterambere ry’isoko rya wafer ya silicon (SiC) riterwa nimpamvu nyinshi zingenzi, kandi gusesengura byimbitse ingaruka zibi bintu ku isoko ni ngombwa. Dore bimwe mubyingenzi byingenzi byamasoko:
Kuzigama ingufu no kurengera ibidukikije: Imikorere yo hejuru hamwe no gukoresha ingufu nke biranga ibikoresho bya karubide ya silicon bituma ikundwa mubijyanye no kuzigama ingufu no kurengera ibidukikije. Gukenera ibinyabiziga byamashanyarazi, imirasire yizuba nibindi bikoresho bihindura ingufu bitera kuzamuka kwisoko rya waferi ya silicon karbide kuko ifasha kugabanya imyanda yingufu.
Porogaramu ya Electronics ikoresha: Carbide ya Silicon irusha imbaraga ibikoresho bya elegitoroniki kandi irashobora gukoreshwa muri electronics yamashanyarazi munsi yumuvuduko mwinshi hamwe nubushyuhe bwo hejuru. Hamwe no gukwirakwiza ingufu zishobora kongera ingufu no guteza imbere inzibacyuho y’amashanyarazi, icyifuzo cya waferi ya silicon karbide ku isoko ry’amashanyarazi gikomeje kwiyongera.
SiC wafers iterambere ryiterambere ryikoranabuhanga rigezweho isesengura rirambuye
Umusaruro mwinshi no kugabanya ibiciro: Inganda zizaza za SiC zizibanda cyane kumusaruro rusange no kugabanya ibiciro. Ibi bikubiyemo uburyo bunoze bwo gukura nko kubika imyuka ya chimique (CVD) hamwe no kubika imyuka yumubiri (PVD) kugirango umusaruro wiyongere kandi ugabanye ibiciro byumusaruro. Byongeye kandi, iyemezwa ryibikorwa byubwenge kandi byikora biteganijwe kurushaho kunoza imikorere.
Ingano nshya ya wafer nuburyo: Ingano nimiterere ya waC ya SiC irashobora guhinduka mugihe kizaza kugirango ihuze ibikenewe na porogaramu zitandukanye. Ibi birashobora kubamo waferi nini ya diametre, imiterere itandukanye, cyangwa waferi nyinshi kugirango itange igishushanyo mbonera nuburyo bwo gukora.
Gukoresha ingufu no Gukora Icyatsi: Gukora waferi ya SiC mugihe kizaza bizibanda cyane kubikorwa byingufu no gukora icyatsi. Inganda zikoreshwa ningufu zishobora kuvugururwa, ibikoresho byatsi, gutunganya imyanda hamwe na karuboni nkeya bizahinduka inzira mubikorwa.
