Doomaha graphite, oo sidoo kale loo yaqaan doomaha garaafka, waxay door muhiim ah ka ciyaaraan geeddi-socodka qallafsan ee soo saarista dhoobada semiconductor. Maraakiibtan khaaska ah waxay u adeegaan sidayaal la isku halayn karo oo loogu talagalay waferrada semiconductor inta lagu jiro daawaynta heerkulka sare, hubinta habka saxda ah iyo kantaroolka. Sifooyinkooda gaarka ah iyo codsiyadooda kala duwan,Doomaha garaafkawaxay noqdeen aaladaha lagama maarmaanka u ah warshadaha semiconductor. Aynu sahamino sifooyinka muhiimka ah ee sameeyaDoomaha garaafkaqaybaha muhiimka ah ee wax soo saarka dhoobada semiconductor.
1. Dulqaadka Heerkulka Sare:
Doomaha garaafkawaxaa laga sameeyay agab garaafeed tayo sare leh oo caan ku ah caabbinta kulaylka gaarka ah. Sifadani waxay u oggolaanaysaa doomaha Graphite inay u adkeystaan heerkulka xad dhaafka ah ee ay la kulmaan inta lagu jiro hababka samaynta semiconductor, sida kaydinta uumiga kiimikada (CVD) iyo daahan silikoon carbide ah. Awoodda lagu ilaaliyo sharafta qaabdhismeedka iyo xasilloonida cabbirka ee xaaladaha kulaylka daran ayaa muhiim u ah hubinta soosaarka semiconductor joogto ah oo la isku halayn karo.
2. Firfircoonaanta Kiimikada:
Graphite, walxaha aasaasiga ah ee loo isticmaaloDoomaha garaafka, waxay muujisaa firfircooni la'aan kiimikaad oo cajiib ah, taasoo ka dhigaysa mid u adkaysata daxalka iyo falcelinta kiimikaad. Dabeecaddani waxay si gaar ah faa'iido ugu leedahay samaynta dhoobada semiconductor, halkaas oo kiimikooyinka adag iyo gaaska falcelinta inta badan lagu isticmaalo. Doomaha graphite-ku waxay bixiyaan jawi badbaado oo loogu talagalay waferrada semiconductor, ka hortagga wasakhda iyo hubinta nadiifnimada alaabta ugu dambeysa.
3. Xakamaynta cabbirka saxda ah:
Doomaha garaafkawaxaa lagu farsameeyay si sax ah si ay u dajiyaan waferrada semiconductor ee cabbirka iyo qaababka kala duwan. Naqshadooda la beddeli karo ayaa u oggolaanaysa in la xakameeyo cabbirka saxda ah, hubinta in ay ku habboon tahay maraqyada iyo yaraynta khatarta dhaawaca inta lagu jiro maaraynta iyo habaynta. Heerkan saxda ah ayaa lagama maarmaan u ah gaarista dhumucda dahaarka isku midka ah iyo saxnaanta dhigaalka ee hababka wax soo saarka semiconductor.
4. Kala duwanaanshiyaha Codsiyada:
Doomaha garaafkau hel isticmaalka baahsan ee noocyo kala duwan oo ah hababka samaynta semiconductor, oo ay ku jiraan epitaxy, faafinta, annealing, iyo dhigista filim khafiif ah. Haddi ay taageerto maraqa silikoon inta lagu jiro habaynta kulaylka ama fududaynta korriinka lakabyada epitaxial, doomaha Graphite waxay bixiyaan la isku halleyn karo dhammaan codsiyada kala duwan. Awoodda ay u leeyihiin inay u adkeystaan soo-gaadhista dheer ee heerkulka sare iyo bay'ada daxalka ayaa ka dhigaysa agabka lagama maarmaanka u ah soo saarista dhoobada semiconductor.
5. Waafaqsanaanta Dahaarka Silicon Carbide:
Doomaha garaafka ayaa si fiican ugu habboon codsiyada ku lug leh dahaarka silikoon carbide (SiC), qayb muhiim ah oo ka mid ah aaladaha semiconductor sare. Waafaqsanaanta garaafka leh carbide silikoon waxa ay sahlaysaa in si hufan oo isku mid ah loo dhigo lakabyada SiC ee substrates-ka, kor u qaadida waxqabadka qalabka iyo isku halaynta. Doomaha garaafka ayaa door muhiim ah ka ciyaara fududaynta habka dhigista, hubinta daboolida isku midka ah iyo xakamaynta saxda ah ee dhumucda dahaarka.
Gebagebadii, Doomaha Graphite waxay u adeegaan sida qaybaha lagama maarmaanka u ah wax soo saarka dhoobada semiconductor, iyagoo bixiya isku darka u gaarka ah ee dulqaadka heerkulka sare, firfircoonida kiimikada, kontoroolka saxda ah ee cabbirka, iyo waafaqid dahaarka silikoon carbide. Kala duwanaanshahooda iyo isku halaynta ayaa ka dhigaya aaladaha lagama maarmaanka u ah hababka wax-soo-saarka semiconductor, taas oo awood u siinaysa soosaarka aaladaha semiconductor tayo sare leh oo tayo sare leh. Maaddaama tignoolajiyada semiconductor ay sii socoto inay hormarto, doomaha Graphite waxay ahaan doonaan hantida lama huraanka ah, wadida hal-abuurka iyo horumarka warshadaha semiconductor.
