Hexamethyldisilazane (HMDS) Supplier in Malaysia
- Also known as
- HMDS
- Hexamethyl Disilazane
Hexamethyldisilazane, commonly called HMDS, is a volatile silazane used for surface treatment, silanisation and selected semiconductor process steps. It reacts with suitable surface moisture or hydroxyl groups to change surface behaviour and can assist adhesion, coating wetting or lithographic process control.
The page covers technical, electronic and surface-treatment grades. Electronic buyers normally specify trace-metal, moisture and non-volatile-residue limits, while coating and industrial users may focus on purity, colour, hydrolysis behaviour and compatibility with the substrate and primer system.
Typical applications include wafer surface priming, oxide and glass treatment, microelectronics processing, adhesion promotion and speciality synthesis. HMDS is not a silicone oil, silicone emulsion or general silane coupling agent, so the process identity should be stated clearly in the enquiry.
Send the substrate or process step, required purity, moisture and residue limits, estimated quantity and delivery location. Packing, documentation and handling details are confirmed for the quoted hexamethyldisilazane grade.

Common questions about hexamethyldisilazane
What is hexamethyldisilazane used for?
HMDS is used for semiconductor surface priming, wafer and oxide treatment, silanisation, adhesion promotion and selected moisture-sensitive chemical processes.
What does HMDS mean?
HMDS is the common abbreviation for hexamethyldisilazane. It identifies this silazane reagent and should not be confused with silicone oil or a generic silane blend.
Which HMDS specification matters for electronics?
Electronic processes commonly qualify purity, moisture, trace metals, non-volatile residue, particle control and container cleanliness against the existing process window.
Can technical HMDS be used for wafer processing?
Wafer processing normally requires an electronic or process-qualified grade. State the tool, surface, exposure conditions and impurity limits before selecting a technical material.
How should I request HMDS?
Include the application, grade, purity and impurity requirements, quantity, required packing and delivery point so the quoted material can be matched to the process.
