Tmah photoresist reaction
Webconditions enable the combination of an acceptable etch rate with a minimum photoresist erosion. The average size of the under-etching at these conditions is about 1.7µm. The etch rate of titanium in sulphuric acid is significantly higher than in orthophosphoric acid. For example a Ti etch rate of 63.2 nm/min in 46% H 2 SO 4 at 80°C was Webfrom the resist solvent PGMEA) increases the de-velopment rate of exposed and unexposed resist. This explains the higher dark erosion of resist with a re-maining solvent concen-tration too high (e. g. in case of an insufficient softbake).

TMAH is most commonly encountered as an aqueous solution, in concentrations from ~2–25%, and less frequently as solutions in methanol. These solutions are identified by CAS number 75-59-2. Several hydrates such as N(CH3)4OH·xH2O. have been crystallized. These salts contain well separated Me4N cations and hydroxide anions (Me is an abbreviation of methyl group). The hydroxide groups are linked by hydrogen bonds to the water of crystallization. Anhydrous TMAH …
