PTFE hte shinggrup da ai hka htung a matu

RANA a PTFE hte shinggrup da ai ammonium tetramethyl hydroxide hpe shinggyin tawn da ai tank hpe PTFE hte shinggrup da nna, n-gun ja ai alkalinity hte san seng ai lam grai law ai electronic-grade trimethylammonium hydroxide (TMAH) hpe hkap la lu na matu galaw da ai. TMAH hpe semiconductor wafer ni hpe jasan jaseng ai hta hte photoresists ni hpe galaw shapraw ai hta lang ai rai nna, metal ions zawn re ai n san seng ai arung arai ni hpe grai hkam sha chye ai. PTFE a chemical inertness gaw tank kaw na arung arai ni hpe n-gun n rawng hkra pat shingdang ya ai majaw, shinggyin tawn da ai TMAH gaw san seng ai lam hpe makawp maga ya lu ai. Dai hta n-ga, PTFE a n-gun n law ai majaw, hka (sh) CO2 shang wa ai hpe pat shingdang ya ai majaw, hka hpe hkap la ai (sh) carbonation galaw ai majaw TMAH a n-gun yawm wa ai hpe koi lu ai.

Ndai hka htung hpe madung hku nna electronic tsi ni hpe galaw shapraw ai hte semiconductor ni hpe galaw shapraw ai hta jai lang ai. Shi a kata na bunghku gaw, n-gun n rawng ai, n-gun n rawng ai hkrang hpe madun da ai majaw, arung arai ngam ai hpe shayawm ya lu nna, batch (sh) specifications amyu myu a TMAH solution ni hpe galai shai na matu loi ai. Dai hta n-ga, tank hpe malu masha-grade sealing arung arai ni hte galaw da ai rai nna, semiconductor hpaga lam hta ultra-san seng ai shingbyi shara ni a matu grai sawng ai ra kadawn ai lam ni hpe hkan sa lu ai. Ndai arung arai gaw core board galaw ai lam ni hpe hkrak hkrak galaw lu na matu ahkyak nga ai.
