Web. Web. TMAH: New Hazard Awareness Concerning an Old Chemical Tetramethylammonium hydroxide (TMAH) is widely used in micro- or nanofabrication as an etchant and developer. In MSD, TMAH is typically one of several ingredients in commercial etching/stripping mixtures, although it may also be used as a pure chemical. Web. Aircraft supply product NAS76A10-026N Misc. Part (NAS76A10-026N) (6595608) from Bushing Manufacturing available at Jaco Aerospace, offering over 1,000,000 aircraft MRO and GSE supply products. Jaco Industrials, Inc. has been recognized as one of the worlds leading distributors for aircraft MRO and GSE supplies. Hazard Description. Refer to a specific product's Safety Data Sheet for more hazard details. An example Safety Data Sheet from Sigma-Aldrich for a 25% solution of TMAH can be found here: Sigma-Aldrich SDS for TMAH 25% The health hazards of TMAH pentahydrate (solid) are very similar to those of the solution, however the solid is a GHS hazard category 3 for dermal acute toxicity, whereas the. Tetramethylammonium Tetramethylammonium ( TMA) or ( Me4N+) is the simplest quaternary ammonium cation, consisting of four methyl groups attached to a central nitrogen atom, and is isoelectronic with neopentane. It is positively charged and can only be isolated in association with a counter-ion. They were developed in 0.26 N TMAH for 60 s and rinsed in DI water. It was found that the resist could not be fully developed at any PAG1 loading. Figure 2 (b) shows response for MF-tBAC(2) resists containing 44 wt%, 50 wt%, or 60 wt% PAG1.
