KOH galaw ai wa a matu PTFE Lined Hkringmang Dap

RANA a PTFE lining KOH Developer shingbyi shara hpe PTFE hte shinggrup da ai rai nna, KOH developer a n-gun ja ai alkalinity hte photolithography galaw ai lam ni hta san seng ai lam grai law hkra ra kadawn ai lam ni hpe hkap la lu na matu galaw da ai re. KOH developer hpe semiconductor photoresist ni hpe galaw na matu lang ai rai nna, n san seng ai nhprang arai ni zawn re ai nhprang arai ni hpe grai hkam sha chye ai. PTFE a inert properties gaw tank kaw na pru ai arung arai ni hpe n-gun n rawng hkra pat shingdang ya nna, n-gun rawng ai shara hpe awu asin byin shangun ai. Dai hta n-ga, shi a n-gun n law ai majaw CO2 shang nna KOH hte n-gun n rawng ai sha K2CO3 byin wa ai hpe pat shingdang ya ai, dai gaw n rai yang developer a pH manu hpe shayawm kau ya nna, developer a akyu hpe madi shadaw ya lu ai.

Ndai hka htung hpe madung hku nna semiconductor core board hte hka htung panel ni hpe galaw shapraw ai hta jai lang ai. Shi a hkrang gaw, n-gun n rawng ai kata bunghku hte loi ai-to-san seng ai hkrang hpe madun da ai majaw, gyin shalat nga ai hparan ladat ni a ngam ai hpe shayawm ya nna, hparan ladat amyu myu hpe galai shai na matu loi ai. Ndai tank hpe nhtoi hte nbung a n-gun hpe shayawm kau lu na matu, nhtoi-koi ai hkrang hte galaw da ai rai nna, photolithography galaw ai lam hpe ngang grin ai hte hkrak hkra galaw lu na matu re. Ndai lam gaw semiconductor galaw shapraw ai line ni hta ahkyak ai karum shingtau ai arung arai langai byin shangun ai.
