Applications

Used as nitride precursor - MOCVD. Precursor to Titanium nitride (TiN) thin films, chemical vapor deposition (CVD). A novel templated non-hydrolytic sol-gel synthesis of titanosilicate xerogels is reported. Acetamide elimination from silicon acetate and titanium diethylamide allows obtaining titanosilicates with a high content of Si-O-Ti bonds but low surface areas. Metal-organic chemical vapor deposition (MOCVD) of TiN thin films at low temperatures and low pressures using tetrakis(diethylamino) Ti (TDEAT) and NH3 is described. TDEAT dissociatively chemisorbs on SiO2 at room temperature or above, resulting in Ti?N bond scission, and Ti?O bond formation.

Notes

Air & Moisture Sensitive. Store in cool place. Keep container tightly closed in a dry and well-ventilated place. Handle under dry protective gas. Store away from strong oxidizing agents, air, water, light, alcohol.
