Kodi ndi mpweya wotani womwe umagwiritsidwa ntchito kwambiri podula utoto wouma?

Ukadaulo wopaka utoto wouma ndi imodzi mwa njira zofunika kwambiri. Mpweya wopaka utoto wouma ndi chinthu chofunikira kwambiri popanga zinthu za semiconductor komanso gwero lofunikira la mpweya wopaka utoto wa plasma. Kugwira ntchito kwake kumakhudza mwachindunji ubwino ndi magwiridwe antchito a chinthu chomaliza. Nkhaniyi ikufotokoza makamaka za mpweya wopaka utoto womwe umagwiritsidwa ntchito kwambiri popaka utoto wouma.

Mpweya wochokera ku fluorine: mongatetrafluoride ya kaboni (CF4), hexafluoroethane (C2F6), trifluoromethane (CHF3) ndi perfluoropropane (C3F8). Mpweya uwu ukhoza kupanga bwino ma fluoride osasunthika akamadula silicon ndi silicon compounds, motero zimapangitsa kuti zinthu zichotsedwe.

Mpweya wochokera ku chlorine: monga chlorine (Cl2),boron trichloride (BCl3)ndi silicon tetrachloride (SiCl4). Mpweya wochokera ku chlorine ukhoza kupereka ma ion a chloride panthawi yocheka, zomwe zimathandiza kusintha kuchuluka kwa kucheka ndi kusankha.

Mpweya wochokera ku bromine: monga bromine (Br2) ndi bromine iodide (IBr). Mpweya wochokera ku bromine ukhoza kupereka magwiridwe antchito abwino odulira m'njira zina zodulira, makamaka podulira zinthu zolimba monga silicon carbide.

Mpweya wochokera ku nayitrogeni ndi mpweya wochokera ku okosijeni: monga nitrogen trifluoride (NF3) ndi mpweya (O2). Mpweya umenewu nthawi zambiri umagwiritsidwa ntchito kusintha momwe zinthu zimachitikira panthawi yocheka kuti ukhale wosankha komanso wolunjika bwino.

Mpweya umenewu umatha kupukuta bwino pamwamba pa chinthucho kudzera mu kuphatikiza kwa madontho a thupi ndi zochita za mankhwala panthawi yopukuta plasma. Kusankha mpweya wopukuta kumadalira mtundu wa chinthu chomwe chiyenera kupukuta, zofunikira pakusankha kwa chopukutacho, ndi liwiro lopukuta lomwe mukufuna.
