Falanqaynta Semiconductor Ultra High Purity Gaas

Gaasaska nadiifka ah ee aadka u sarreeya (UHP) waa dhiiga nolosha warshadaha semiconductor. Iyadoo baahida aan horay loo arag iyo carqaladaynta silsiladaha sahayda caalamiga ah ay kor u qaadayaan qiimaha gaasta cadaadiska aadka u sarreeya, naqshadaynta semiconductor cusub iyo hababka wax soo saarka ayaa kordhinaya heerka xakamaynta wasakheynta ee loo baahan yahay. Soosaarayaasha semiconductor, awood u yeelashada in la hubiyo nadiifnimada gaasta UHP ayaa aad uga muhimsan waligeed.

Gaasaska Nadiifinta Sare (UHP) Aad ayey ugu Baahn Yihiin Soosaarka Semiconductor-ka Casriga ah

Mid ka mid ah codsiyada ugu muhiimsan ee gaaska UHP waa qallafsanaan: Gaaska UHP waxaa loo isticmaalaa in lagu bixiyo jawi ilaalin agagaarka qaybaha semiconductor, taas oo ka ilaalinaysa waxyeelada waxyeelada leh ee qoyaanka, ogsijiinta iyo wasakhowga kale ee jawiga. Si kastaba ha ahaatee, hawlgelintu waa uun mid ka mid ah hawlo badan oo kala duwan oo ay gaasaska ka qabtaan warshadaha semiconductor. Laga soo bilaabo gaasaska balaasmaha aasaasiga ah ilaa gaaska falcelinta ee loo isticmaalo etching iyo annealing, gaasaska cadaadiska aadka u sarreeya ayaa loo isticmaalaa ujeedooyin badan oo kala duwan waxayna lagama maarmaan u yihiin inta lagu jiro silsiladda sahayda semiconductor.

Qaar ka mid ah gaasaska "core" ee warshadaha semiconductor waxaa ka mid ahnitrogen(oo loo isticmaalo nadiifinta guud iyo gaaska aan shaqayn),argon(oo loo isticmaalo sidii gaaska hore ee balaasmaha ee etching iyo falcelinta dhigaalka),helium(oo loo isticmaalo sidii gaas aan shaqaynayn oo leh sifooyin kulayl-wareejin gaar ah) iyohydrogen(wuxuu ka ciyaaraa doorar badan oo ku saabsan nuugista, dhigista, epitaxy iyo nadiifinta balaasmaha).

Sida tignoolajiyada semiconductor-ku u horumartay oo is beddeshay, sidaas oo kale gaasaskii loo adeegsaday habka wax soo saarka. Maanta, dhirta wax soo saarka semiconductor waxay isticmaashaa gaasyo kala duwan oo badan, laga bilaabo gaasaska sharafta leh sidakryptoniyoneonsi loo falceliyo noocyada sida nitrogen trifluoride (NF 3) iyo tungsten hexafluoride (WF 6).

Baahida sii kordheysa ee nadiifinta

Tan iyo markii la abuuray microchip-kii ugu horreeyay ee ganacsi, dunidu waxay marqaati ka ahayd koror la yaab leh oo ku dhow-jibaarida waxqabadka aaladaha semiconductor. Shantii sano ee la soo dhaafay, mid ka mid ah siyaabaha ugu macquulsan ee lagu gaari karo horumarinta waxqabadka noocaan ah waxay ahayd iyada oo loo marayo "cabbirka cabbirka": hoos u dhigista cabbirrada muhiimka ah ee dhismayaasha chip-yada jira si loogu tuujiyo transistors badan meel bannaan. Intaa waxaa dheer, horumarinta naqshadaha cusub ee chips-ka iyo isticmaalka qalabka wax-goynta ayaa soo saaray wax-qabadka qalabka.

Maanta, cabbirrada muhiimka ah ee semiconductors-ka-goynta hadda aad bay u yar yihiin in cabbirka cabbirku aanu hadda ahayn hab macquul ah oo lagu wanaajiyo waxqabadka aaladda. Taa baddalkeeda, cilmi-baarayaasha semiconductor waxay raadinayaan xalal qaab qalab cusub iyo qaab-dhismeedka chip 3D.

Tobaneeyo sano oo dib-u-qaabaynta aan daalin waxay ka dhigan tahay aaladaha semiconductor-ka ee maanta aad ayey uga awood badan yihiin microchip-yadii hore - laakiin sidoo kale aad bay u jilicsan yihiin. Imaatinka 300mm tignoolajiyada wax-soo-saarka wafer-ka ayaa kordhisay heerka xakamaynta wasakhda ee looga baahan yahay wax-soo-saarka semiconductor. Xataa wasakhda ugu yar ee habka wax soo saarka (gaar ahaan naadirka ama gaasaska aan shaqaynayn) waxay u horseedi kartaa burburka qalabka masiibada - sidaas awgeed nadiifinta gaaska ayaa hadda ka muhiimsan waligeed.

Warshada wax-soo-saarka semiconductor-ka caadiga ah, gaaska nadiifka ah ee aadka u sarreeya ayaa durbaba ah kharashka ugu badan ka dib silikoon laftiisa. Kharashyadan ayaa kaliya la filayaa inay kordhaan marka baahida loo qabo semiconductors ay kor u kacdo ilaa heerar cusub. Dhacdooyinka Yurub ayaa khalkhal dheeri ah ku keenay suuqa gaaska dabiiciga ah ee cadaadiska aadka u sarreeya. Ukrain waa mid ka mid ah dhoofinta ugu weyn adduunka ee nadiifinta sareneoncalaamadaha; Duullaanka Ruushka wuxuu la macno yahay saadka gaaska naadirka ah in la xaddiday. Taasina waxay keentay gabaabsi iyo qiimaha gaaska kale ee sharafta leh sidakryptoniyoxenon.
