Ixabiso Elikhethekileyo leGreen Silicon Carbide Micropowder kwiShishini leSemiconductor
Ishishini le-semiconductor lisoloko lifana netekhnoloji ephezulu, apho abantu behlala bexoxa ngezihloko eziphezulu ezifana noomatshini be-photolithography kunye noyilo lweetships. Nangona kunjalo, kweli shishini, ezinye izinto ezibonakala zingabalulekanga zidlala indima ebalulekileyo.Umgubo omncinci we-silicon carbide eluhlazayenye yezinto ezinjalo. Namhlanje, masithethe ngale nto ikhethekileyo, sisebenza ngokuzolileyo kwindlela yokuvelisa i-semiconductor.
Mandiqale ngebali elinomdla. Kunyaka ophelileyo, ndiye kwimiboniso yorhwebo yeshishini le-semiconductor. Kwi-booth engenamsebenzi, iinjineli ezininzi zazixoxa ngenzondelelo ngesiqwenga sesixhobo sokusila. Ndiphulaphule ngenyameko, ndandibeva bethetha ngokuphindaphindiweyo nge-"green silicon carbide micropowder." Ndandididekile ngelo xesha; yayivakala ngathi yi-abrasive yendabuko yemizi-mveliso, ngoko ke ingadityaniswa njani ne-precision semiconductors? Kamva, ndaqonda ukuba kweli shishini, okukhona izinto zilula, kokukhona zibaluleke ngakumbi.
Yintoni kanye kanye i-green silicon carbide micropowder? Ngamafutshane, yinto eyenziwe ngumntu eqinileyo, enyibilikiswa kwisithando sombane esishushu kakhulu ngezinto eziluhlaza ezifana nesanti ye-quartz kunye ne-petroleum coke. Igama layo livela ekubeni icocekile kakhulu kwaye inombala oluhlaza owahlukileyo. Musa ukuyithatha lula le ntwana incinci; ubunzima bayo bulandela idayimani kuphela, kodwa inamandla aphezulu obushushu kunye nokungasebenzi kakuhle kweekhemikhali.
Kwimveliso ye-semiconductor, ukutyibilika kwe-wafer kumisela ngokuthe ngqo isivuno se-chip. Oku kusizisa kwizakhono eziphambili zei-silicon carbide eluhlazai-micropowder: ukupolisha ngoomatshini bekhemikhali (i-CMP). ULao Zhang, injineli yenkqubo kwi-wafer fab, usebenzisa umzekelo ocacileyo: “Kufana nokunika i-wafer 'unyango lobuso'—ukuthambisa amaqhuma kunye nokungalingani ngaphandle kokushiya imikrwelo. I-micropowder ye-silicon carbide eluhlaza ifana namasuntswana e-microcrystalline kukhathalelo lolusu oluphezulu—ithambile kodwa iyasebenza.” Enyanisweni, ekwenzeni iitships, nokuba zilishumi ezimbalwa ze-micron yokungalingani zinokubangela umjikelo omfutshane okanye ovulekileyo.
Ulawulo lobushushu lucelomngeni oluqhubekayo kwishishini le-semiconductor. Njengoko ukuhlanganiswa kweetships kusanda, ukusasazwa kobushushu kuya kusanda.Umgubo omncinci we-silicon carbide eluhlazainesakhono esikhethekileyo kule nkalo: ukuyifaka kwizinto eziqhuba ubushushu kuphucula kakhulu ukusasazwa kobushushu. Injineli yobushushu kwinkampani eyaziwayo yeetshiphusi indixelele ukuba, “Ngoku sisebenzisa i-micropowder ekhethekileyo eluhlaza ye-silicon carbide kwi-thermal paste yethu ephezulu, ephucula ukusebenza kakuhle kokusasazwa kobushushu ngaphezulu kwama-20%. Oku kusindisa ubomi kwiiteknoloji zenkqubo ye-5nm kunye ne-3nm.”
I-green silicon carbide micropowder ibaluleke ngakumbi ekuvelisweni kwezixhobo ze-semiconductor. Izinto ezininzi ezibalulekileyo kwiimashini ze-lithography kunye noomatshini bokukrola, ezinokubiza amashumi ezigidi zeeyuan, zifuna ukuchaneka okuphezulu kakhulu koomatshini bokukrola. Umzekelo, iinkqubo zokukhanya zeemashini ze-lithography zifuna ukuba tyaba kakhulu kwesibuko, nto leyo ebangela ukuba kusetyenziswe i-green silicon carbide micropowder.ukugaya ngokuchanekileyo. Igqala elinamava eminyaka engama-20 lathi, "Ukusebenzisa le nto kufuna kakhulu. Ubungakanani bamasuntswana, uxinaniso, kunye nexabiso le-pH zonke kufuneka zilawulwe ngokuchanekileyo; nokuba kuthe tye okuncinci kunokuchaphazela isiphumo sokugqibela."
Kubalulekile ukuqaphela ukuba ngokunyuka kwezinto ze-semiconductor zesizukulwana sesithathu, i-green silicon carbide micropowder ifumene isicelo esitsha. Izixhobo ze-semiconductor ezisekwe kwi-silicon carbide ngokwazo zifuna i-green silicon carbide micropowder ukuze zigaywe kwaye zipolishwe ngexesha lokucubungula. Ngumjikelo onomdla—ukusebenzisa i-silicon carbide ukucubungula i-silicon carbide. Umlawuli wezobugcisa wenkampani yezinto ezintsha ze-semiconductor wancuma wathi, “Kufana nokusebenzisa idayimani ukusika idayimani; kuphela njengoko izinto zinokuqondana ngokwenene.”
I-green silicon carbide micropowder ikwadlala indima ekhethekileyo kulawulo lomgangatho. Iifektri ze-semiconductor zifuna ukugcinwa kwezixhobo rhoqo, ingakumbi ukucocwa kwemigca yokuhambisa kunye namagumbi okusabela. Ngenxa yokuba i-green silicon carbide micropowder ayinayo ikhemikhali kwaye ayivelisi ungcoliseko olutsha, yeyona nto ikhethwayo kwiinkqubo zokucoca. Injineli yolondolozo ityhile ukuba, “Xa kuthelekiswa nezinye izinto ezirhabaxa,i-micropowder eluhlaza ye-silicon carbideayishiyi ii-ion zesinyithi eludongeni lwangaphakathi lwezixhobo, nto leyo ibalulekileyo ekugcineni imeko-bume icocekile xa kuveliswa iitships.
Kakade ke, yonke into inendawo yokuphucula. Imingeni ekhoyo ngoku ejongene ne-green silicon carbide micropowder ixhomekeke kakhulu kulawulo lweendleko kunye nokuhambelana komgangatho. Inkqubo yemveliso enzima kunye nokusetyenziswa kwamandla aphezulu kunegalelo kwixabiso layo eliphezulu. Ngaphezu koko, ukuhambelana kuzo zonke iibhetshi yingxaki ephambili kubasebenzisi. Nangona kunjalo, iinkampani ezininzi eziphambili zasekhaya sele zijongana nale micimbi, zinciphisa kancinci kancinci umsantsa kwiimveliso ezingenisiweyo ngokuphucula iinkqubo zemveliso kunye neenkqubo zolawulo lomgangatho.
Ukujonga phambili, njengoko iteknoloji ye-semiconductor itshintsha iye kwiinkqubo ezincinci kunye namanqanaba aphezulu okudibanisa, imfuno ye-green silicon carbide micropowder iya kuqhubeka ikhula. Oku kuyinyani ngakumbi kwiindawo ezintsha ezifana neetships zobukrelekrele bokwenziwa, iitships zonxibelelwano ze-5G, kunye neetships zokuqhuba ezizimeleyo, ezibeka iimfuno eziphezulu ngakumbi ekusebenzeni ngokuchanekileyo kunye nokusebenza kokusasazwa kobushushu. Oku kuvula uluhlu olubanzi lwezicelo ze-green silicon carbide micropowder.
Ndikhumbula igqala leshishini lisithi, “Ishishini le-semiconductor lifana neqhwa. Oko abantu bakubonayo kuyilo lwe-chip kunye nokuveliswa okukhulu ngaphezulu komphezulu, ngelixa izixhobo, iinkqubo, kunye nezixhobo ezingaphantsi komphezulu zisisiseko esixhasa lonke ishishini.” I-micropowder ye-silicon carbide eluhlaza yinxalenye ebalulekileyo yezi zinto zisisiseko. Isenokungabi yinto ekhangayo njengomatshini we-lithography, kodwa zezi zinto “zingabonakaliyo” ezixhasa uphuhliso lweshishini lonke le-semiconductor.
Ngexesha elizayo xa usebenzisa i-smartphone okanye uqhuba imoto ekrelekrele, mhlawumbi cinga ukuba emva kwezi mveliso zobuchwepheshe obuphezulu kukho igalelo lezinto "ezingenaxabiso" ezifana ne-green silicon carbide micropowder. Kaloku, inkqubela phambili yalo lonke ishishini ayinakwahlulwa kwezi "qhawe" zithuleyo nezizinikeleyo.
