Diisopropylaminosilane (DIPAS）

As an important silicon-based precursor material, DIPAS is widely used in vapor deposition and atomic layer deposition techniques to manufacture silicon-based semiconductor thin film materials, such as silicon oxide, silicon nitride, and silicon carbide. These silicon-based semiconductor thin film materials have been used in the manufacturing of high-end capacitors, solar cells, storage devices, lasers, light-emitting diodes, and gas sensing components.

4. Safety warning

Product status
Severe burns caused by skin contact. It has a stimulating effect on the upper respiratory tract and conjunctiva, and can cause pulmonary edema in severe cases.
Hazardous characteristics
Intense reaction with water releases flammable gases, which can cause combustion and explosion.
Saving method
The product should be placed in a sealed stainless steel container and operated in an inert gas to avoid contact with water and air.
Take protective measures (such as gloves, goggles, and face shields) when operating steel cylinders with the human body.
Fire extinguishing methods
Dry yellow sand, stones, fire blankets, and dry powder fire extinguishing agents. Water, carbon dioxide and foam are strictly prohibited.
Leakage emergency response
Isolate the contaminated area of the leakage, evacuate unrelated personnel, stay away from the leakage area, and be upwind. Emergency response personnel should wear
Wear a breathing mask and full body protective clothing to avoid inhaling vapors, smoke, gases, or dust. While ensuring safety
In this case, take measures to prevent further leakage or overflow. When there is a small amount of leakage, dry sand or inert adsorbent materials can be used
Absorb the leaked material and build embankments to control a large amount of leakage. Attached or collected materials should be stored in suitable sealed containers,
And dispose of it according to relevant local laws and regulations. Remove all ignition sources and use fire-resistant tools and explosion-proof equipment.
Health hazards
Severe burns caused by skin contact. It has a stimulating effect on the upper respiratory tract and conjunctiva, and can cause pulmonary edema in severe cases.
