PTFE haanta kaydinta dahaaran ee Tetramethylammonium Hydroxide

RANA's PTFE ee safan ammonium tetramethyl hydroxide haanta kaydinta waxaa lagu dahaadhay PTFE, loogu talagalay in lagu buuxiyo alkalinity adag iyo shuruudaha nadiifnimada sare ee elektiroonigga{0}fasalka trimethylammonium hydroxide (TMAH). TMAH waxaa badanaa loo isticmaalaa nadiifinta waferrada semiconductor iyo horumarinta sawir-qaadista, waxayna aad ugu nugul tahay wasakhda sida ion birta. Dareen-la'aanta kiimikada ee PTFE waxay ka hortagtaa walxaha taangiga inay ka soo baxaan wasakhda, hubinta in TMAH-ga kaydsan ay ilaaliso nadiifnimadeeda. Intaa waxaa dheer, qulqulka hooseeya ee PTFE waxay ka hortagtaa qoyaanka ama CO₂ inay soo galaan, sidaas darteed ka fogaanshaha hoos u dhaca fiirsashada TMAH sababtoo ah nuugista qoyaanka ama karbonation.

Haanta kaydinta waxaa ugu horrayn loo isticmaalaa soo saarista kiimikooyinka elegtarooniga ah iyo soosaarka semiconductor. Derbigeeda gudaha waxa ku jira naqshad siman oo aan kala go 'lahayn, kaas oo yaraynaya halista hadhaaga maaddooyinka oo fududeeya beddelka xalalka TMAH ee qaybo kala duwan ama tilmaamo. Intaa waxaa dheer, haanta waxaa lagu dhisay cunto{2}} agab daboolaya heerka, oo buuxinaya shuruudaha adag ee deegaanka kaydinta nadiifka ah ee warshadaha semiconductor. Qalabkani wuxuu muhiim u yahay hubinta saxda ah ee hababka wax soo saarka guddiga asaasiga ah.
