Semixlab Glassy kaarboon-dahaarka garaafyada

Substrate kaarboonka dahaarka leh ee garaafiga ah waa walxo isku dhafan oo leh graphite sida maaddada aasaasiga ah, la dahaadhay ama lagu dahaadhay kaarboon dhalo leh, kaas oo isku dara dhaqdhaqaaqa wanaagsan iyo iska caabinta heerkulka sare ee graphite oo leh kiimikaad sare ee tamarta, cufnaanta iyo astaamaha dusha siman ee kaarboon dhalo leh.

Si loo daboolo baahiyaha isbeddelaya ee warshadaha, waxaan soo saarnay faylal kala duwan oo badeecado ah oo si buuxda u qalabaysan si loo buuxiyo shuruudaha teknoolojiyadda daahan jiilka soo socda, iyadoo la hubinayo inaan bixin karno xalal la jaan qaada horumarkii ugu dambeeyay ee garoonka semiconductor.

Codsiga:

Marka loo eego goobaha codsiga, kala duwanaanta codsiga ee garaafiga kaarboonka leh ee dahaarka leh waa mid aad u ballaaran. Dhinaca qalabka semiconductor, sababtoo ah iska caabin heerkul sare oo heer sare ah, caabbinta oksaydhka iyo korantada, waxay noqotay wax ku habboon soo saarista guddiyada wareegga isku dhafan ee waxqabadka sare leh iyo aaladaha elektiroonigga ah. Dhinaca alaabta shubista joogtada ah, garaafiga kaarboonka leh ee dahaarka leh ayaa si weyn loogu isticmaalaa dahaarka kristalizer ee mashiinnada shubka joogtada ah sababtoo ah dufanka wanaagsan iyo iska caabinta heerkulka sare, si wax ku ool ah u wanaajinaya waxtarka shubista joogtada ah iyo tayada wax-soo-saarka. Intaa waxaa dheer, dhinacyada hawada, warshadaha nukliyeerka, birta, warshadaha kiimikada, iwm, garaafiga kaarboonka leh ee daboolan ayaa sidoo kale ka ciyaara door aan la bedeli karin.

Adeegyada la bixin karo:

Falanqaynta xaaladda codsiga macaamiisha, agabka u dhigma, xallinta dhibaatada farsamada.

Astaanta shirkadda:

Semixlab waxay leedahay 2 shaybaar, koox khubaro ah oo leh 20 sano oo waayo-aragnimo agab ah, oo leh R&D iyo awoodaha wax soo saarka, tijaabinta iyo xaqiijinta.

Faahfaahin Gaar ah:

a. Codsiga ugu muhiimsan: Substrates garaafyada dahaarka leh ee kaarboonku waxay leeyihiin codsiyo ballaaran oo dhinacyo kala duwan ah sida semiconductors, tamarta, tignoolajiyada dahaarka gaarka ah iyo tignoolajiyada soo baxaya sababtoo ah sifooyinka gaarka ah ee jirka iyo kiimikada. Horumarka joogtada ah ee tignoolajiyada, baaxadda codsigeeda iyo muhiimada ayaa la filayaa inay sii balaarto.

b. Habka diyaarinta:

Habka dahaarka:

Substrate-ka garaafiga waxa lagu dhex milmay kaarboonaysable polymer precursor iyo dahaar lebis ah ayaa lagu sameeyay daahan lafdhabarta, daahan buufinta ama kaydinta uumiga kiimikada (CVD).

Kaarboonization heerkul sarreeya:

Daawaynta heerkul sare (1000-3000 ° C) ee jawiga aan firfircoonayn (sida argon) waxay u beddeshaa polymerka kaarboon dhalo leh, kaas oo si adag ugu xidhan substrate-ka garaafka.

c. Halbeegyada qeexitaanka asaasiga ah:

dhumucda dahaarka (la doortay iyadoo loo eegayo deegaanka daxalka, oo dhumucdiisuna si mug leh 50-100μm); cufnaanta garaafka substrate (cufnaanta sare waxay u adkaysataa dhexgalka); jawiga isticmaalka (oxidizing/aan shaqayn); Heerka kulaylka ≤10 ℃/daqiiqo (yaraynta cadaadiska interface); Isticmaalka heerkulka hawada ≤600 ℃ (gaaska aan shaqaynayn ayaa loo baahan yahay haddii ay ka badan tahay)

Isbarbardhigga waxqabadka muhiimka ah

Goobaha codsiga ee ugu muhiimsan

Taageerada xaqiijinta silsiladda deegaanka

Gudbiyay xaqiijinta isku halaynta ee soosaarayaasha sida Sinosteel
Shirkadda iyo FangDa.

Habka wax soo saarka caadiga ah

Dooro substrate (qalabka graphite leh porosity of 10% -15%) → Nadiifinta dusha sare (1000-2000 rpm / min, 30-60min) iyo preheating (150-200 ℃, 1-2h) 500-1000mpa·s 2500 ℃)

Iyada oo loo marayo hal-abuurnimo tignoolajiyadeed oo joogto ah iyo horumarin wax soo saar ah, Substrate-ka dhalooyinka leh ee kaarboonka dahaarka leh ee Semixlab waxa uu horumar ka gaadhay agabka garaafyada gudaha, isaga oo buuxinaya baahida sii kordheysa ee garaafiga kaarboonka dahaarka leh ee garaafyada gees-goynta sida baabuurta tamarta cusub, nidaamyada kaydinta tamarta, iyo agabka semiconductor. Haddii aad u baahan tahay inaad hesho waraaqo cadcad oo tifaftiran oo faahfaahsan ama aad diyaarsato tijaabada muunad, fadlan la xidhiidh kooxdayada taageerada farsamada.
