What causes a reduction in the etch rate of TMAH?
As a result, the etch rate anisotropy is modified. For TMAH, the best results are achieved with nonionic compounds like PEG, NC-200, and TRITON, which simultaneously improve the roughness of {100} and {110}. They also cause a reduction in the etch rate of {110} even at high TMAH concentrations [54–56].
Why are surfactants added to Koh and TMAH?
The addition of surfactants to KOH and TMAH can modify the etching rate anisotropy, reducing the undercutting at the convex corners and improving the surface roughness. For instance, both {100} and {110} can be simultaneously smoothened by the addition of NC-200 in low-concentrated TMAH, eliminating also the undercutting, as a bonus [56,57].
How is tetramethylammonium hydroxide used in metathesis?
Solutions of TMAH may be used to make other tetramethylammonium salts in a metathesis reaction with ammonium salts, whereby the anion is derived from the ammonium salt. The reaction is driven in the desired direction by evaporative removal of ammonia and water.
What is the half life of tetramethylammonium hydroxide?
Its half-life in 6 M NaOH at 160 °C is > 61 h. TMAH undergoes simple acid-base reactions with strong or weak acids to produce tetramethylammonium salts whose anion is derived from the acid. Illustrative is the preparation of tetramethylammonium fluoride:
