Tetramethylammonium Hydroxide Supplier Malaysia
- Also known as
- TMAH
- Tetramethyl Ammonium Hydroxide
Tetramethylammonium hydroxide is a strong organic base supplied commercially as an aqueous solution and commonly abbreviated as TMAH. Semiconductor and electronics buyers use tightly controlled grades in development, etching and other microfabrication steps.
Selection starts with concentration and then the required purity envelope. Electronic grades may define trace metals, particles and ionic contamination, while general industrial material may be specified by strength, appearance and selected impurities.
TMAH applications include positive-photoresist development, semiconductor processing, display manufacturing, research and specialised chemical synthesis. It is separate from ammonium hydroxide, sodium hydroxide and other alkaline developers even when they serve related process functions.
Send the required concentration, grade, analytical limits, quantity, packing preference and Malaysian delivery location. The quotation confirms compatibility of the offered specification, documentation, packing and commercial terms. Supply is subject to applicable requirements.

Common questions about tetramethylammonium hydroxide
What is tetramethylammonium hydroxide used for?
TMAH is used as a photoresist developer, semiconductor process chemical, anisotropic etchant and strong organic base in selected synthesis operations.
Which TMAH concentration should I request?
The required concentration is process-specific. Send the photoresist, etching or synthesis requirement and the accepted concentration tolerance for matching.
What distinguishes electronic-grade TMAH from industrial grade?
Electronic grades normally require tighter trace-metal, particle and ionic-contamination controls, while industrial grades are selected mainly by strength and general purity.
Can TMAH be quoted for photoresist development?
Yes. Include the resist system, target concentration, contamination limits, quantity and packing requirement so the developer grade can be evaluated.
What details are required for a TMAH supply enquiry?
Provide concentration, purity grade, analytical limits, intended process, quantity, container preference and delivery point. Supply is subject to applicable requirements.
