High Quality Cas 102-54-5 Supplier - Supplier Industrial/Electronic Grade TMAH 25% Tetramethylammonium Hydroxide – Zhuoer

Tetramethylammonium hydroxide (TMAH or TMAOH) is a quaternary ammonium salt with the molecular formula [(CH₃)₄N]⁺[OH]^-, and is the simplest member of the class of organic quaternary ammonium compounds. One of its industrial uses is for the anisotropic etching of silicon. It is also used as a basic solvent in the development of acidic photoresist in the photolithography process. Since it is a phase transfer catalyst, it is highly effective in stripping photoresist. It is also used as a surfactant in the synthesis of ferrofluid, to prevent agglomeration.

1) In the aspect of analysis, tetramethylammonium Hydroxide can be used as polarographic reagent.

2) In terms of product purification, it was used as ash free alkali to sediment some metallic element.

3) in electronic industry , especially as positive resister developer , silicon wafer wet etchant and super clean solution for CMP process.

4) in the manufacture of integrated circuits, liquid crystal displays, printed circuit boards, capacitors, sensors, and many other electronic components.
