Dhibaatooyinka hadda jira ee diyaarinta 200mm 4H-SiC crystals mainl

1) Diyaarinta kiristaalo abuurka 200mm 4H-SiC tayo sare leh;

2) Xajmiga cabbirka weyn ee heerkulbeegga qaab-la'aanta iyo xakamaynta habka nukliyeerka;

3) Hufnaanta gaadiidka iyo kobcinta qaybaha gaaska ee ballaaran ee hababka koritaanka crystal;

4) Dildilaaca kristal iyo kororka cilladda oo ay keento culeyska kulaylka ee cabbirka weyn.

Si looga gudbo caqabadahan oo loo helo xalal tayo sare leh oo 200mm SiC ah ayaa la soo jeediyay:

Marka la eego 200mm abuur crystal diyaarinta, beer ku habboon heerkulka beerka, iyo ballaadhinta shirka ayaa la darsay oo loogu talagalay in lagu xisaabtamo tayada crystal iyo ballaadhinta size;Laga bilaabo 150mm SiC se:d crystal, samee soo-celinta abuurka crystal si aad si tartiib tartiib ah u ballaariso SiC crystasize ilaa ay ka gaarto 200mm;Iyada oo loo marayo korriin badan oo crystals ah iyo processiig, si tartiib tartiib ah u hagaaji tayada crystal ee aagga fidinta crystal, oo wanaaji tayada 200mm kiristaalo abuur.

Marka la eego 200mm crystal conductive iyo diyaarinta substrate, cilmi baaris ayaa hagaajisay heerkulka feld iyo qulqulka garoonka design ee crystalgrowth size weyn, qabtaan 200mm koriinka crystal SiC conductive, iyo xakamaynta isku mid ah doping.Ka dib habayn adag iyo qaabaynta crystal, 8-inji koronto ah oo 4H-SiC ah oo leh dhexroor caadi ah ayaa la helay.Ka dib markii la gooyo, shiidi, dhalaalid, farsamayn si aad u hesho wafers SiC 200mm leh dhumucdiisuna waa 525um ama wax ka badan
